- Watch how your glasses are made after your sight test.
This is what happens behind the scenes once you have your prescription ready and you have picked your frames and lenses.
Things may vary depending upon your prescription, requirements and location, but the general practice is the same.
There are two types of lenses that your prescription will be, Stock lenses, or Surfaced lenses.
Stock lenses are mass produced and are available in thousands of different prescriptions and lens types. They are pre made and ready to use which makes the turn around time quicker and these types of lenses can also be held in stock by your eyewear or manufacturer. There are limitations to these stock lenses in terms of what prescriptions and labs types that are available.
This is where Surfaced lenses come in to play, these lenses are custom made, specifically to your prescription, measurements, frame type and other important factors. Varifocals, Bifocals, complex or higher prescriptions are all examples of surfaced lens. As they are custom made, they do take longer, depending where you are in the world.
The blocking and tracing process is standard procedure for all types of eyewear manufacturing, albeit changing ever so slightly depending upon what type of lenses and/or frame you are ordering.
The tracer scans the inside rim of the frame to take various measurements, it also tells the other glazing/edging machine what shape to cut the lenses.
The second element is to "block" the lens. This is the process of applying a special plastic block with an adhesive pad to help it stick to the lense. It's this block that holds the lens in place in the chucks (where the lens is held) during the cutting/edging/glazing process. The location of the pad on the lens is crucial as it is apparent to the various elements of your prescription and personal measurements.
When the lens is ready for cutting, the information is sent over from the other machine so it knows what shape to cut the lenses to.
The edging/glazing machine will use various process and tools within the machine, depending upon what the lens type and frame are. Times will vary during this process but the process for most lenses is under 5 minutes per lens. Complex lenses such as rimless (with holes that need to be drilled) or special lens materials such as polycarbonate normally take longer.
When the lenses are cut, they are then ready to be assembled with the frame. Plastic frames (not all) may require a frame heater to make the plastic softer and easier to work with when inserting the lense. A metal frame that requires screws, simply requires and optical screwdriver for assembly.
I always use a thread lock on the screw thread as it prevents them from falling out or coming loose over time. I do not use this type of thread lock when using polycarbonate lenses as the chemicals from the thread lock can damage the lens.
Once the glasses are assembled, it's then time to put them through quality control. Here lots of different aspect are checked, such as the prescription, measurements, order details and much more. Here is where I also inspect the lenses and coatings for quality. The glasses are only able to leave the lab once they are checked off and they have passed all checks.

Thank you for showing and sharing, how glassing are made. What you do is a big help to everyone!!
@@juliavilla8088 that's so kind of you, thank you for your support, really appreciate it 😁
Hey Colin!
brother could a -0.25 cylinderical be ignored. is it safe to do so? Also, i read somewhere that your cylinderical number doesnt change. is thst true?
Holy crap mate, sorry to say but I couldn't understand you and English is my first language. Maybe next time talk a tad slower haha.
@@tuffguy8656 hi, thanks for your question. Your -0.25 cylinder power is just the prescription to correct a very small astigmatism, it's so low that the next number down is 0, to give you an idea. Your prescription like this isn't a representation of your eye health. Everyone is individual and you should take the advice from your Opticians as they will know what is best for your personal needs. As an idea, I have a higher cylinder power than you and I don't often wear my glasses, but that's just me, everyone is different, your eyes may be more or less sensitive to a prescription. Hope this helps.
I've been wearing glasses for 2 years now and when I first got them I was shocked at how clear everything looked nowadays I wear them all the time and they're really helpful
Me to about two years .. i had enough when i was driving during the night i did not see the street lights .. it looked like a bad video game with the light just hanging in the air ..
Hi Addy, thanks for your comment, that's great to hear. What areas do you notice the biggest difference?
Do you have any coaitngs on your lenses to help with the lights at night time?
I got a pair of my friends glasses on and i saw super clear i was so shocked that my regular eye sight was very blury
@@blazzy3241 do you wear glasses normally yourself?
I’m a qualified spectacle maker of 15 years, trust me this guy knows his stuff, his equipment alone costs £40k+. Loved the video. Keep it up bro. ✌🏻
Hi 🙂 Really appreciate your kind words, thank you 👍 Glad you liked it. Thanks for your support ✌ Have you used the Essilor edging Mr Blue system before? Colin 😎
I found your video very informative.
Thank you

Whoa, I used to be so curious as to how the lenses were made - you’ve answered a 20 year query!
I had my first glasses in 1956 (wearing all the time), still go to the same practice as I did then but now 3 optometrists later. Back then it was glass lenses only which were heavy as were the frames, this was well before the invention of transition lenses which I find absolutely wonderful.
Hi Rob, thanks for your comment and for watching 🙂 That's great to hear. Yes, glass is not a common material now, it still has its uses in some circumstances. It's amazing to see how much the technology is changing, even just in the quality of the transition. How long have you had Transitions for?
@@precisionopticseyewear
I would have been one of the very early ones to have transitions in Australia. If memory serves me correct and I think it does I had to wait for them to be done in Singapore and then returned to my optometrist. The year I do not remember. I give thanks my optometrist is progressive in his practice ideas.
@@rodb9262 That is really interesting. Nowadays we only have an hour or two to wait and our glasses are ready to pickup
im a dental lab tech applying to be an optical lab tech tomorrow. had no knowledge of your kind of work until today. thanks for the info!
Always wanted to know how my glasses were made, this video was very entertaining and informative. Thank you so much!
Thanks for watching, appreciate your support, glad you found it useful 😁 Colin
I am watching your video as im looking to possibly do an apprenticeship in the lab making glasses. I have been a nurse for 15 years and i have definitely outgrown that career. I go in 9th February to have a chat with them...im always happy to learn new thing's 😀
Hi Colin , great presentation of the process involved in making lenses . Very informative.
Thank you very much 🙂
Everything's so mechanized.
Makes the job easy. Beautiful
It definitely helps but it is all far from easy 😌 Still requires years of skill and knowledge to be able to get everything done perfectly from start to finish. The video does make it seem rather easy to be fair 😁
Thank you, there wasn’t much video out there for this 🙏
Thanks for watching, much appreciated 🙏
Thank you for the video. Very informative ❤
I found this by searching, "filling out eyeglass prescription," as I wanted to get a better feel on how my prescription lens are filled. I've had one returned lens to my regular health care provider because of an incorrect filling that caused strange viewing sensations, and a couple abnormalities with a mail order company, where the tint began to chip prematurely. Your video provides some interesting insight into the process. Thank you.
I’m so excited for new glasses I’ve been having trouble in school with these glasses I have rn and I’m so excited-😭 aaaaa
Well it's great to see that your excited! What style of frames have you gone for?
Very informative. Thanks.
Thanks Carl, much appreciated 🙂👍
Been wearing glasses since grade 3 and they have come a long way they can make these lenses now so small and stylish with cool frames. I don’t like contacts cause glasses are way less maintenance and if you wanna take off your glasses you just take them off. Not the story with contacts you take them off then they gotta sit in a solution too not dry out. I have glasses that dim to the sunlight like sunglasses really helpful on sunny days
Hi Ryan, thank you for your comment and foe watching 🙂 Yes you're definitely right. Optics is a forever changing and adapting environment. There are constantly new products and techniques being developed to make lenses look nicer and nicer. I've tried contacts before and they aren't for me either, I know lots of people that love them though! Good to hear you are using your photochromic lenses that change in the sun 🌞 Have you used them before and what colour do you have?
Exactly what I wanted to know 🙂
Greetings from croatian optician ❤️

Wow that's cool! Greetings! Thank you for your support! Colin 😎😁
Super helpful!!!!
Thank you, much appreciated, Colin 😎
Thanks!!!
Hi..the way u carry ur video(s) content is too good..!! new subscriber from Chennai (India)❤️❤️
That's very kind of you to say! Thanks for your support!
That cool keep it up
Took my little girl for her first eye test recently and turns out she has bad vision eyes like mommy ❤️ now she wears glasses and loves them 🤓😊🥰 she told me she could finally see the illustrations on the bedtime story books I've been reading her. She's adorable with her cute little specs ☺️
Thank you for your comment, this is lovely to hear, that's fantastic. What a lovely thing you have done, it will make the world of difference for her 🙂🤓👍
That is wonderful.
My glasses are done on a friday . Thx for the explination :)
That's great, what did you go for? Glad the video helped out too!
@@precisionopticseyewear i have gone bcz i couldnt see at the whiteboard
My father has been an optician for the past 45 years and I have also been an optician for seven years and and there are also older ways to cut the lens into shape after making sure you got the lens prescribed right and we have an automatic machine that does all that but we also use older machines to cut the lens into shape and fit them in to the chosen frames
Waw thanks for sharing this🙏
thank god, i hoped they could actually put lens back in bcs mine got popped out. £120 glasses aswell. Now that ik that you just heat the frame up and pop it back in with your hands is so stress free
I never knew. the only video I needed
Thanks for watching, glad it was useful 👍
Wearing glasses since I was 4 years. Things have really evolved in the 30 years after that
Thanks for watching, yes, things are constantly moving, cha and adapting, it's great to be able to create something for someone that makes such a difference 😀
I love this is channel
Hi, thanks for watching and for your support. Much appreciated 🤓 Colin
I’m going to the eye doctor tomorrow.. and I’m not sure how long it’s going to take to get my glasses.. because I’m really excited, I have to get them before school so I want my glasses as fast as possible
Hi, it will really depend on your prescription and your Opticians set up. Like us for example, I have hundreds of lenses in stock and all the machines to make the completed glasses in about 20 minutes, other places may need to send off for the work to be completed, so already your looking at a couple of days just for couriers times. Hope they aren't too long for you. Are these your first glasses? Thanks for watching and commenting too!
So cool. Wow.
Thank you Nicole! Much appreciated!
Thanks just became an eyeglasses wearer. Just was wondering.
Thank for watching, glad it was useful 👍 Colin
This was a helpful video. Can you plz make a video on those machinaries?
Hi Paul, many thanks! Sure, I'll put it on the list to get to 👍
Thank you
Thank you for watching 👍🙂
I’ve been wearing glasses for around years. All of the sudden, my vision got slightly worse, and needed a new prescription. I always wondered how this stuff worked.
Watching this while waiting on my new glasses.😩
Thank you for watching 🤓 Have you worn glasses before?
i love your video i have to show this to my students tomorrow coz i have one student who will be wearing her glasses Tomorrow and her mom asked us to explain it to them so this will be part of the explanation. shes afraid that her daughter will be bullied because of her glasses
Hi! Thanks for watching and commenting! Ah that's fantastic, glad it will help out! Thank you for your support too. Hopefully this will make a difference. Let me know and keep me posted 🙂
The most important and interesting aspect has already been completed by the start of this video... But thc
Wow the process looks simple with the machines involved, how come it takes 2 weeks to receive them ??
how to order an edged/cut lens for rimless. is there a standard shape list to which one adds A + B + DBL dimensions. thanks
Hi, I want to ask that is it enough if I buy my glasses online with the prescription? Is there a difference in the lenses placement or something like that?
I just don.t know how to describe the legend who created these machines
Ouu ty cool I was looking at my frames and wondering how they got my lens in and now I know .
Hi 👋 glad it helped out! I get asked that a lot! Have a nice Christmas 🎄!
@@precisionopticseyewear same to you😊
I hit the like icon fam
Thank you! Appreciate the support 👍 🤜🤛
So these lenses come with a factory scratch coat and AR coating, correct?
I’m getting my first set of glasses soon ( I am a preteen ) I hope they work well because I have been trouble seeing in school this video was very informing and I subscribed :-)
Hi Cheeseburger (I will assume that this is not your birth name). Thanks for watching and subscribing, really appreciate the support. Hope your new glasses make things better for you! Let us know how you get on once you have them! Remember, it might take you a while to get used to them.
Colin 🙂
@@precisionopticseyewear yeah, I hope I adjust easily 😬 😅
@@cheeseburger5716 let us know how you get on!
@@precisionopticseyewear ok i got my glasses and it feels so weird!!! I can see so many things I couldn’t before!!!
I have a trial shift working in specsavers, the job I will get if this goes well will be working in the lab making the glasses. Are there any tips you can think of, or anything I should know going in? I will of course be doing my own research but I wondered if you might have some insights that might help. Oh and great video, thanks for making it
Hi Ash, thanks for watching and your comment too. First of all congratulations and best of luck. When is your trial shift?
Funny enough, this is where I started of my optical career! Working in the lab is really cool, there be processes and procedures to lots of things, some of which are done for efficiency etc. Lots of labs have different set ups, with a different sized team.
Just enjoy the process. Even if you start literally cleaning some job trays...its all what you make of it. Don't be scared to take notes. Specsavers like to see when a team member can equally be independent and relied upon. Don't try and be a hero straight away, but learn as much as you can, go on and ask to go on any courses they put forwards.
In terms of your trial shift, all I can say is what I would look for in a new employee, as I was part of the management at Specsavers where I had to work with new employees plus interviews and trials etc. I'd personally look for someone who I believe I can get along with and they seem to have a level of reliability, responsibility. A good employer of this role will hire based upon personality.... not skill. You are new, you're not going to know anything. Skills can be taught....personality can't.
I love wearing my glasses for gaming it really helps me with sniping in Roblox 😊
A lot of frames have a slight wrap. Why do some places flatten the frame? It completely changes the look.
Can you do a video on stain/frosted vs polished edges on different type of glasses. My glasses have a white ring around them face on, on a -4 prescription on a 1.67 lens. I’m thinking polished edges will make that less visible but read about a rainbow effect? I would love to see one lens in a clear plastic frame with polishing and one with the normal frozen/stain look to see if the white ring gets removed.
Hi, great question and request. I'll put this on the list to do, so keep an eye out for it. Yes, I know what you mean, the rainbow effect or internal reflections can sometimes be an issue with thicker edges such as a high minus prescription. I'll put something together to see if it helps 🙂 Are your glasses polished or not?
@@precisionopticseyewear my glasses are not polished and have anti reflective coating. I do not have the rainbow effect currently. I am considering to get the edges polished to reduce the white ring but would like to know how common and how annoying the rainbow effect could be.
Ok, this makes sense, I have an idea, what kind of frame do you have?
@@precisionopticseyewear grey transparent plastic full rim frames cat eye shape for single vision
The shops charge extra big bucks for all sorts of protective layers like UV, antidust etc. but i'm not seeing you applying any of it ?
Nice 👍
Thank you 😁🤓👍
I also work as an optician ..but i only use manual edging .
Great to have you watch and comment thank you. Amazing, where abouts are you based?
I wanted to see how the actual glass is combined together
Dear Colin.
I am old now and have eyes tested every 18 months or so and recent test revealed a slight changes requiring new bifocals which I normally have in high index material and coated etc. I could see from the new prescription that there was and increase from -6 to -6.5 D and that subtle changes had been made to the axis and prism.
Got the new glasses back the other day and right from the off it was obvious that the right eye lens was wrong as all images where ghosting and out of focus. Where in all this automation could things have gone wrong? My Optician has of course sent these new frames and lenses back to the lab for re-doing both lenses or at least the faulty one.
Thank you for your message. Yes an interesting one there....thete are a few areas that could cause this.
As you say there is alot of automation but only based on what the Optician (a human) can prescribe. Where a human is testing a human its a mixture of opinions/experiences based on what you see in that test time, how it's interperated and then made.
The test could be absolutely fine, it may be too much of a jump for your eyes to settle with, you may need a stepping stone in between.
The lenses may be have more or less Prism than required.....
The list goes on 😅
It could be more than one... from experiences ghosting is normally something to do with the Prism so it will be interesting to see what they say.
When will they let you know?
@@precisionopticseyewear
Perhaps I will never know exactly. They will just present me with my new glasses again with the re-done len's/lenses and then I will be able to tell whether they are successful. Unlike many high street chain Opticians, mine writes outs prescriptions in long hand rather with somewhat difficult to read entries. Places such as Specsavers are all printed out properly and clearly!
I want to buy my own frame and take them to add the prescription, but I don’t know if they will use the nonprescription lenses it comes with. I don’t want to buy UV light protection lenses on them and not be able to use them.
I saw a video on camera lenses being made from the optical glass in a very hands on way with many steps. Are glasses lenses made the same way?
Hi, thanks for your question and for watching. Some may go through the same or similar process. Different materials may be used too. I'm not 100% sure of camera lens materials but any optical lenses for eyewear are made from resin.
I'd probably say that camera lenses are glass....but I could be wrong?
How do you make prescription glasses more comfortable and adjust the sides??
There are lots of ways and unfortunately no one answer, as lots of frames are different and can be adjusted differently. Your optician will be able to make any adjustments for you and look at them for a perfect fit. Are they hurting or slipping down or both?
I doubt our local clinic have this kind of tech.
Many places do not. Everywhere is different, some have the equipment but only do basic orders and send out more complex ones
hiiii precious optics eyewear
well working
Isn't it up to the person if they want thinner lenses
Hi, I got my yearly routine checkup done and got my glasses 2 weeks ago. My power got increased from - 5 to - 6 and axis also changed .. I'm feeling like my right eye is paining... If I go to optician and Check. If there is any slight power correction is there can we alter that or made changes in my newly got spectacles?
Hi, thanks for your comment. So the different and new prescription will normally take time to get used to. How long is very individual and there is no rule. Some people may notice more of a difference other than others. I would recommend that you see your opticians and go through this with them. They may well say that the increase may be something that you will get used to or they may make a prescription in between this as a stepping stone. Hope this helps.
Colin
Do the opticians send you the frames or do you have the frames already?
I have been wearing glasses for 12 years now
Thanks for watching, hope it was interesting 😊
question, if there are any scratches on the glas what type of tools in the process making is possible to do so?
Hi, thanks for your question 😎 Do you mean what processes and tools are used to remove scratches? If so, then there is normally nothing that can be done unfortunately. If it was a very light scratch or a coating that is lifting, then there are chemicals to strip off this top layer coaitng, however it would still show the scratches on the lens itself if it was deep enough. Generally speaking the only thing to do is to replace them, as buffing, sanding and polishing the lens surfaces can effectively alter the prescription. Hope this helps 👍
Colin
In the blocking process, where do u get the pads from? Do u make then yourself or buy them? And what are they called exactly
Hi, the grey hard pads are specific to the machinery, the black adhesive pads are called glazing or blocking pads, I purchase them in. What country are you located?
Can i get the frame from anywhere? I have a hard time finding frames that fit my face so can I order one online and have the lens inserted separately? Or do i need to have a specific type of frame?
Hi Kim, ghabks for watching and also for your question.
I can't comment on other eyewear providers, but for myself, I am always more than happy to use frames that my client may have found from elsewhere.
Check with who is making you lenses for you and see if they are happy to use a frame that you supply. Look at the measurements of your current frae and use these to help pick one that's either smaller, same size or bigger, depending upon what you want and need.
There will be 3 measurements that you will see that look something like this
45□17 135 (numbers will be different)
The biggest number before the □ is the width of the lens, the smaller number after is the distance between the lenses (bridge size) and the 3 diget number is the length of the side/arm.
Hopefully this helps!
Thread lock. Also prevents user from removing lenses to clean the frame. And why are screw heads in metal frames always damaged so the screws can't be undone!?
Do you recommend Zenni Optical frames for surface lense ?
Hi Akisha, unfortunately I wouldn't be able to comment as for one I have nor used this company before and secondly it would vary depending on lots of other factors. What kind of lenses are you looking to get from them? Many thanks Colin
I dont understand why most eyeglasses takes more than week just to be ready
It really depends on what lenses and prescription you need. Also what set up your supplier has. If they do not make themselves then 3 or 4 days is potentially just transit time between lab and supplier 👓
Come to India you will get your glasses done in 1 hour, proud to be an optician
I have parmer erythema and I'm bricking myself to go to the doctors tomorrow
Hi, thank you for your comment. How did you get on?
Hey I wanted to know in how many years we have to to do eye check up and change the glasses. I think it's been a 4 and half years I haven't changed my glasses.
The times are dependent upon your age, family history and your medical history. Usually anything between 6 months which is pretty short or up to 2 years, anything in between too. It's good to be checked regularly for your health
My local optics ordered my lens with no UV protection when I purchased with that feature. They told me they have to reorder the ones with UV. Are they going to just throw away the new lens with no UV? If so, why can't I just kept that and let them cut the new lens with UV to a new pair of frames?
So if I put my prescription in my own Oakley’s that have the words prizim on it would that stay on them?
Hi, thanks for watching and commenting, if you went direct to Oakley then they add this etching onto the lens. From anywhere else I.e me for example, then no, as the Prizm brand and technology is owned by Oakley. Hope this helps 🙂
Kind regards
Colin
I'm an Optician, good explained...
Thank you, appreciate your support 🙏
Question…my wife just got a new prescription eyeglass for close up reading and work. She has good faraway vision, we are seniors. The lense and frames were fairly big for a reader frame but that’s what they recommended. She could not use them, she said when she looked down through the lenses it was blurry, like looking down at the keyboard for typing. Straight ahead to the monitor was ok. Couldn’t wear them , took them back and explained her problem. The doctor said they just ground the line of sight in the middle? I told her, they are readers, there shouldn’t be a line of sight, the lense should all be the same power. Does this sound correct? So they are now making her a new pair with a smaller frame, comparable to her old frame.
Hi Fred, thanks for your question. So really there could be a few things going on here really. Hard to say without a bit more information. With regards to the issues with the visit for computer work, did your wife mention that she wanted to be able to use the computer as well?
The reason I ask is that many times, a reading prescription is made for near use work, I.e reading a book, when you start getting a bit further away, at arms length for example when using a computer, an intermediate prescription can be required instead of reading.
Has your wife tried the newly remade glasses yet?
Kind regards
Colin
@@precisionopticseyewear
She hasn't gotten her new frame and lens yet. I still think he was blowing smoke about about the line of sight being not where she needed it. She's able to use readers for computer work now, so I don't know why they would make them any different. I wasn't to impressed with the finish of the lenses, had quite a few pit marks like they weren't polished well. Maybe that was acceptable for their QC?
Hi Colin, have been trying to order prescription sunglasses unline but keeps telling me no lenses available. I noticed when I entered 4.75 cyl it only goes to 300 do I need to buy something that covers my distance glasses. Thank you
Hi Sean
Yes, many online retailers have limitations on the prescription range that they are happy to supply. Even though this is irritating, it's done yo actually help rather than hinder. Some prescriptions, such as yours, may require additional measurements, more accuracy and a specific frame selection. Where do you normally get your glasses from?
How are the lenses for rimless frames being cut? Do u puncture the lens to fit those screws for the Arms and nose bridge of a rimless frame?
The lens is cut to the final shape and the wholesale are drilled out, each lens normally has 4 holes and we use a very small drill bit. It has to be very precise or the frame parts will not fit and the frame will look wonky 😁
@@precisionopticseyewear also what's the best way to clean metal framed specs?
Where do you learn how to do this job?
I personally learned alot from my first job at Specsavers where I started off pretty much at the bottom and then worked up throughout the company over quite a few years, learning the various parts of optics and doing courses etc 🙂 in 2016 I was in a position to start my own optical business 😎
Hi I have a question. My glasses used to be a strong prescription but I got new glasses and the doctor lowered them because the strong ones can damage my eyes. But the thing is I see perfectly clear with the strong prescription, I see so blurry with the ones he lowered. It makes me mad because I can’t see the world clear and I have to squint my eyes now.
Thanks for your question, I understand your frustration. The thing is we have to have trust In opticians, but also listen to your body. You should speak to them and let them know what's happening.
If my prescription has changed do they need to do this process all over again or just add the different?
Hi Sadeem, if you require new lenses then this will be the process whether they update your current frame for new lenses or if they provide new frames all together. Hope this helps
Colin
2 weeks😃,where i go it takes like 3 hours to make the lens
2 weeks is probably the longest ot would ever take really. Stock lenses as mentioned (that we hold on-site) can be used to make a pair of glasses in 20 minutes. It's all to do with the prescription and lens type 🤓 what type of lenses do you have?
Keratoconus high prescriptions glasses dont seem comfortable. Walls and ground appear bent. Why?
Sounds like you are experiencing the increase in your Cylinder power. This can give the feeling of warped lines etc. If it does not get better at all you should speak with your Optician. There is no rule book on how long it should take to get better. How long have you had the problem for?
Have been wearing glasses for a year and two months now but my glasses doesn't last
So um..
I put on my mom's glasses for a laugh and realised things were a bit clearer, not a crazy difference but things felt extra crisp and 4k if you know what I mean. And when I took them off ngl felt like a bit of a downgrade. My vision has always been pretty great and it still is alright but when I went to a restaurant reading the small prints off the sign from the menu above the cash register was a little bit tricky and quite annoying and also sometimes my eyes water for no reason. So now idrk what to do and I'm not sure if an eye appointment would be worth it or not and idk if I need glasses
Hi, thanks for your question and for also watching. The best thing to do would be to get your eyes tested, they can check the health of your eyes as well as seeing if you require prescription glasses or not. If your ever in doubt or concerned, then always get yourself seen. Hope this helps, let me know how you get on. Colin
@@precisionopticseyewear thank you! I like drawing and making art on my ipad alot so maybe that has something to do with it hm idk.
@@JacksWorldAnimations yes see what they say. Remember to rest your eyes occasionally when using your Ipad or any computer. The 20, 20, 20 rule suggests- taking a break of at least 20 seconds, every 20 minutes and to look at least 20 feet away.
Colin 🤓
so can i buy frames online and take them to my eye doctor to get them to my specs ?
Hi, thanks for watching and for your comment. Yes you can! Well, I can't speak for every business, but I do this all the time for my clients. Some places won't want to do it, but there are plenty that probably will. Always have a shop about and get a few prices for your lenses
Hope this helps 🙂 Colin
So basically I can use any frames I choose for my prescription lenses? I've never had to wear glasses before do I'm new to this
Hi Jim, pretty much yes. There are some combinations of frames, lenses and your face shape and colour that will work better than others, but along as your prescription and requirements aren't too exotic then you should give various style a try 😎
you know how long itll take till i receive my glasses?
Hi, I wouldn't know unfortunately, if you have ordered some from your opticians you will have to ask them 🙂
You're an eye doctor, do you have advice? I'm nervous, I'm only 15 and I'm blind as a bat 😔 -12 prescription. I can't see anything without my thick ol glasses. It's so hard
Hi Olivia, thank you for your comment. I would always make sure that you have a spare pair of glasses, I would try not to worry as it's out of your control. Make sure you attend your scheduled sight tests so that the health of your eyes can be monitored 🙂
Hello plz anyone reply.in 2017 my eye doctor gave me -9 and -11 high myophia glass.i was using it comfortably.but this year my new doctor gave me -10 in both eyes.but still I feel more comfortable with -9 and -11 glass??now which one I should use?is it harmful to use same prescription for many years??can I use both prescription in the same time ?? Plz reply😞😞??
Hi, thanks for your question. The thing is that Opticians are highly trained professionals, so we should have confidence in what they are prescribing us, however, we also know our own body, especially eyes. The differences you are noticing may just be a period of adapting to th new prescription, especially if you have been used to the old one for some time. Equally so, yous should also speak to your Optician, sometimes even though the prescription that is given is technically and clinically correc, sometimes a "stepping stone" might have to be added to get you there. So for example, the new prescription may be too much of a big jump, you may need something in between and en have this new one in a year or two for example. The best thing to do is to speak to your optician, they can also check over the glasses too and make sure everything is ok. Hope this helps!
What does 50/150 vision mean is it good or bad
I can't comment or give you medical advice based on this information, but this result basically means that you can read the test letter at 50 feet where someone with very good/normal vision can read it at 150 feet. So 20/20 is deemed the norm. These numbers don't correspond to the health of your eyes. The numbers you have mentioned are all about you quality of vision which is called your visual acuity. There is much more in depth information about this and this is a very brief explanation. Hope this helps thought!
Did they explain anything to you about your results?
Can you take lenses out from a frame
Yes we can. With a plastic frame we use heat to make it easier sometimes, a metal frame requires screws to be undone to remove the lenses, hope this helps. Colin
I once had glasses...lost them and I'm getting new ones on 24th 2022 (tommorow
Good job on getting some new ones ordered! What frames are you getting?
IF YOU ORDER ONLINE FROM SITES, AND ITS "RUSH SHIPPING" these can take premade or they have a servicr line, its possible the frames are ready too and its just the lens! dont worry! :) just make sure its trusted!
for my main, i have - and +, so mine take so long due yo that 🥲😭
How do you measure that PD on lenses is correct?
Thanks for watching and for commenting. I take my clients PD my using an el device called a pupilometer or by using a traditional ruler. I can also check by marking the lenses and by cross referencing these with their existing glasses if a new client. Colin
@TheDenix8: There's a free App for both I-phone & Android called "GlassesOn".....that's what I use. Its very easy to use and only takes a couple of minutes to measure your own PD if you're buying your glasses online.
How is cylindrical value and axis incorporated? Example: -0.75 with -0.25/61
You can only have an axis if you have a cylinder power. The axis basically refers to the orientation of the lens. If you have no cylinder power and only a spherical power, then the orientation does not matter hence why you will have no axis there. Cylinder powers are there to correct astigmatism, which is the slight elongation of the lens. Hope this helps 🙂
@@precisionopticseyewear - Thanks for the response. I was querying on how actually is that manufactured ?
@@Enemji it will be dependent upon what lens the prescription is being made into and the material. It may be ground down digitally or injection like polycarbonate etc. There are many processes, we don't really get involved in that side, that's called a surfacing lab, we are geared more as a glazing lab.
@@Enemji If you look at the video frames 0:33-0:38 (about 5 seconds) you'll see that they have pre-made lenses in all manner of sphere and cylinder combinations (S and C markings). So they don't have to 'make' the lens, even when Cylinder is involved. There are other YT videos that show how lenses are ground to make a unique prescription.
Got a question. So i been wearing my pair of glasses for 2 years and then i decided to change my lenses on them since they were all scratched up. Got my pair with the new lenses on them but the lenses didn’t fit properly and i was told the reason why is because my glasses shrunk over the 2 years i wore them. Can this be true ? I feltlike it was a dumb excuse for not doing a final inspection. My glasses had no bottom frame for the lenses.
Maybe they just want you to buy a frame as well. Or they made mistake in cutting and measuring
Even if your frames had "shrunk" there is still no real excuse for poor fitting lenses unless the frame is damaged etc. Sounds like they have scanned the existing shape of the original lens and the new one has been cut too small. A shrinking frame would make loose lenses, if anything it would make them tighter. Ask them to remove the lenses and tighten the supra cord at the bottom, it should pull the lens in tighter
What is the difference between making lenses for reading and making lenses for distance?
Hi, thanks for watching and commenting 🙂 Not much really. The differences between the two will be things such as the measurements that I use and the power of the lenses. Sometimes the frames used will be slightly different in terms of size. I.e reading glasses can sometimes be smaller for example.
Hope this helps
Colin
@@precisionopticseyewear This does help. Thanks for explaining it!
My glasses are for distance, and I wanted to know!
My pleasure 🙂 is this your first time getting glasses?
@@precisionopticseyewear No, it is actually my 3rd time, but I love getting them. I always get two different pairs!
@@catgirl7765 ah that's nice 🙂 well enjoy them! It's good fun when you enjoy picking new styles etc 👍
Have you ever had lenses crack on you during the process?
Hi Paul, thank you for watching and commenting. Over the years they're have been times when lenses crack, split or fail for various reasons, sometimes human error, machine error or a faulty lens. The lenses are made from a resin/plastic material so they don't crack on the same way as glass but they can and do still crack, chip and split if something happens. Fortunately enough, this is a vary rare thing in my lab 🙂 Hope this helps 👍
Many thanks
Colin
