When I was a kid I had an optometrist that would literally tint every pair of lenses he got in even if you ordered clear, just very lightly. He said it helped with eyestrain and things. Interestingly I don’t think he charged for that so he must’ve just really loved cooking lenses.
We have a saying --- "Less light = less sight." If you can see a tint then it is blocking (some) light. I'm sure their intentions were good but maybe not the best idea?
John Seegers you are a natural teacher - great information as always.
Thanks!
Another Great tutorial. I have not tinted lenses yet but when I do I will always remember:
UV First
Tint Second
Thank you!
As always, great video. Good info to supplement classes. As a retired video producer, complements for the new format and getting so much mileage with one camera.
Thanks! We actually use 2 Canon T6i's and I had the GoPro running (you can see it on the edge of the tank) but it created some kind of formatting issues so Keith left that footage on the cutting room floor. John
Thank you for creating this
That's a great explanation! Thank you 🙏
Thanks for watching!
Impressive content. We here in India have a similar method but different equipment and machines for this.
Hi Laramy very good explained...Mr. Laramy, that was my doubt, which was first, the tint or the UV, now I know... UV first and Tint second...thank you...
Sir great work thanks
Great video
Thanks
Thanks for this video! I'm trying to add an in-house tinting lab. Do you mind explaining what can be done/how it would work to add a BLUE-LIGHT FILTER tint and is it possible to add one that is CLEAR? Currently we out-source this but I'd love to add this ASAP in house. Thanks in advance!

I don't know of a blue selective that doesn't have a residual blue sheen. But that doesn't mean that it doesn't exist. We have a clear AR! If you are near Anderson SC I'd let that tint tank system I have go. John
Interested in information, can tempered glass be tinted? Larger glass be tinted, if adequate tinted is used? Can you possibly reach out? Thanks!
Is it possible to change the current existing eyeglasses lenses' tint colour?
Thanks
In your opinion, what would be the best VLT range for low light conditions? and bright sunny conditions?
I wear an oakley golf lens for daily wear, even indoors......and it's a 30%. Low light you'll get some strain because it IS a little dark. I would say 45-50%.....but obviously this is just my opinion. I drive at night with my golf lenses, but they are also a rose base. That helps a lot with the color contrast.
Hi. Can you tint lenses that originally has an anti blue light coating?
No.
Hello there,
I was wondering if it is possible to tint a clear sunglass lense (guessing plastic) with that sports yellow full edge AND the UV protection?
[Looking to tint, or get tinted, a pair of "lenses" (plastic) on my favorite pair of Oakley sunglasses; nowhere else sells them in the yellow I so desire!]
Thank You!
Probably not. That lens is probably polycarbonate and most likely wouldn't tint very well if at all. That lens would also have to be in perfect condition. Depending on the frame and lens retention you could certainly have a new pair of lenses made for that frame. SV (non-prescription) tintable poly lenses shouldn't cost you that much at all. Just find a good independent optical that should be a no-brainer for them. If you have some crazy over-the-top Oakley it will get more complicated. John
@@LaramyKOptical Is there a name for such a business that could do that for me, then? That is, what can I type into Google to find one nearest me?
Additionally, thank you greatly for responding so quickly!

Great and helpful video! Thank You! Ha! Looks like a monster used his hands at 39:57 :)
This is a very informative & learning experience. I came across this video because I am a airsoft player and I've been researching how to color my flashlight lens. After watching this video I have questions.
1. Is there a purple & green tint ?
2. If so, can you tint Lenax/ polycarbonate ?
3. Also if so, will it project that specific color once flashlight is turned on ?
Thanks in advance keep up the great work!
Certainly you could mix a blue-green but I'm not so sure of purple. No you can't tint polycarbonate. You can tint optical lenses with poly if they have a special coating. I really have no idea what would project through a light/lens. The reverse is what we are after. You might want to play around with "gels" which are designed to do what you want. (think theater stage lighting)
Better thing to do is to purchase colored plexiglas & cut disk to fit. Another option is to purchase Rosco stage-light filter sample book & back the lens with a circle cut from that.

Yes there is a purple tint..
Go to Cerium visual technology
Where there are a range of colours available.
In the video, I can see that you have UV treatment for normal lens. So can we apply UV treatment for tinted lens as well?
That is in the video --- you UV treat the clear lens then you apply the tint of choice.
Hi John, I dipped the 1.67 index lenses into pink colour; however they came out as purple. Do you have any way to fix it?
Tinting depends on so many factors I can't say for sure. Is the 1.67 a "tintable" product? You can try neutralizer and then play with temperature and see if it makes a difference. What does a CR-39 look like in the same tint pot, at the same temp, for the same time?
@@LaramyKOptical the 1.67 lenses are tintable. I will try to neutralize them as you said. Thanks for your help.
I’m an optician. Our lab used to allow patients to order tints with premium AR. Now they have changed the policy to solid tints can only be combined with lower tier AR. Also if you have a gradient tint, you used to be able to add any type of AR. Now you cannot add any AR to a gradient.
Also same with photochromic. Used to be allowed to add tint with your photochromics. Now they don’t allow it.
What is the REAL REASON they would do this? To make things easier? Less specialized training? Cost?
Drop me an email through the OpticianWorks website. John
@@LaramyKOptical please share your mail id.
Bit of an odd question to ask- but we've had trouble doing bifocals for a while to the point of just ordering anything over a grade 1 (43%) surfaced so we don't have to deal - the issue we've had is that the main area of the lens either side of the seg gets a kind of dark/light line from trying to do it ourselves... It doesn't matter how hot, how long, what colour or RX... they always turn out the same :( It also doesn't matter if we put em in seg facing down- my worry was that the ridge of the seg was "catching" the tint and making a layer but even upsidedown it still does it ... Any advice you think?
Please drop me an email through the OpticianWorks website and I'll make sure the tint guy at the lab gets this question. Tint does tend to collect a little darker along the top of the seg but it sounds like your problem goes beyond that and you tried upside-down already. John
@@LaramyKOptical I'll have to when I get the time! Thank you for the reply c:
Can custom made welding lenses be produced?
I believe all the possible welding lenses are already being/have already been produced. Now a pair of safety glasses for under your welding helmet that is something else.
what kind of tint do irlens syndrome users go with?
See: www.callbpi.com
Do these dyes work on glass too (as opposed to plastic)?
Whoa - great question. No, a lens of glass has the "color" mixed within the glass during creation. As far as I know it cannot be changed, darkened or lightened.
@@LaramyKOptical Thanks for the reply. I'm a filmmaker and was curious about making my own DIY neutral density filters. The good 4x 5.65 filters cost about $400 - $500 each. Since the color is baked in and optical color performance has to be spot on, I can see why these cost so much but I'm always looking for ways to make things work on a budget. Or possibly looking into manufacturing these if I can source the equipment and technologies needed.
Watched it all
I image that photochromatics like transition and the Zeiss are only done by them, not independents
Also, are their gray to mirror photochromatics?
No independent wholesale labs can buy the branded blanks to make surfaced and then finished lenses. Unless you mean the actual manufacturing of the product from monomer. No variable mirror that I know of. Rudy Project does or at least did have a flash silver clear to dark.
Can dyes be stored for later use?
Yes. Find a good old fashioned Mason or canning jar. Or I suppose any glass container with a good seal. It'll be a tad messy and tricky but it can be done. I think BPI may have a few helpful tools?
Hi sir

how to remove the tint or to lightnen up the lenses ?
Explained in detail in the video.
How come my 80% grey tints come out a little purple?
DOH! There is an answer to that question. What it is I don't know. Toss it up on OptiBoard and I'm sure you'll get a good answer. If you don't let me know and we'll go another route. (I think it is too low a temperature.) John
can you do one on mirror lenses I always wonder how they add the mirror... I specifically curious how they make transition lenses clear to dark 😅
Mirror coatings aren't much different than AR coatings. Same equipment. See the other videos on that. Lenses darken through several different ways, chemicals Inherent in the material or cast or a coating layer.
@@LaramyKOptical do you sell lenses yourself where we can ship the frames to you? if so how much would it be for some poly brown lenses with gold flash mirror...
@@varriovlogs We are a wholesale lab that does uncut lenses. So, no on two counts. Sorry. Poly brown with a mirror shouldn't be hard to track down. I think they may even come stock in SV.
@@LaramyKOptical one last question sorry for the inconvenience so i bought online from a website and i order transition xtractive with the gold mirror but they do not come with transition authenticity card can they just be using photochromic technology from other labs and saying their transition and if so js theirs even a much different other than the brand...
@@varriovlogs If they are using Transitions Lenses with the registered trade mark R (capital T capital L) then probably no. Essilor has an army of lawyers tracking that kind of thing. If they used transition then yes possibly. I never gave out the authenticity cards for stuff, always thought it was a little silly. (Just IMO)
I bet its fun dying easter eggs at your house 😂
Warming up the tint tank now!
why did it take longer for Polly to tint
Good question I will answer this,
Cr have more porus property as compared to poly.. So it longer.
Can you do a cosmetic tint on Transition lenses?
I would put that firmly in the "no" category. I guess that is basically what the color "transitions" are for. There is a video about those.
@@LaramyKOptical I have transition lenses but indoors they remain clear, I'm looking at the Transitions XTRActive as I heard they retain somewhat of a tint?
@@Barnabas45 The goal for "transition" lenses is that they do get full clear indoors. That is kind of the Holy Grail if you will. 100% clear inside and a deep dark sun outside. If you want a lens that retains some residual tint inside I'd actually look at older technology and don't take it the wrong way but the cheap off brand stuff. Those will be more likely to keep some tint inside. And although I said no - there is a chance you may find an optician willing to find some changeable tint lenses in the right material and with the change activator within the lens that might drop them in the tint tank for a few minutes and see what happens. Now that you have me thinking I'd do it but I don't have the tools anymore. It would depend on what you are wearing SV or progressives on costs. You could play with SV for a few dollars but progressives it would be cost prohibitive. John

Hi, excuse me,
Is that 180 degree on C or F?
F
@@LaramyKOptical Thank you!
If it was centigrade, the 180° would boil the liquid
Bought a pair of glasses. The maker said, after delivering to me, that it's made a type of lens mateial that cannot be tinted. What material is that? Can you make a video or explain what type of plastic lens or glass lens can be tinted? The maker also said tint reduces the vision!, I feel a slight tint helps with floaters . What are your thoughts 🤔
Several lens materials are impossible or next to impossible to tint but it depends on many things. If you got an AR coating on the lenses then any tinting would have to have been done prior to that being applied (bad idea anyway). Sorry - but - the light tint stuff is all perception. If you can see the tint color it means that light is being reflected back hence not entering the eye. Less Light = Less Sight. BUT - BIG BUT - If you love a light tint and feel it helps then get what you want/like.
@@LaramyKOptical Thank you. And one more question; can consumers directly reach out to your lab to have their prescription lenses be made by you? Or you only work with optitions ?
@@roxan4817 If you drop me an email through the OpticianWorks website I'll see if we have any customers near you. Be sure to give me an address. John

Nice hand at 39:55
My assistant used to show up in videos all the time... nowadays it is few and far between. It found hand model work and got all uppity and wanted more money.
Anyway to Remove tint on glasses ?
Answer is in the video.
@@LaramyKOptical cant find it.
@@fw1367 Depending on many factors a normal tint can be removed or lightened by "neutralizer." It is one of the pots in a tint tank so we can correct/lighten tints. Fresh job, CR-39 = no problem! I've heard people using basic dish soap and getting similar results - never tried it myself.
@@LaramyKOptical thanks. 🇸🇪
@@fw1367 You are welcome.
I laughed so hard at 39:57
My assistant made many appearances in earlier videos I think that was its last appearance. You are probably among the few who even noticed. ;-) John
Are Suppose to wear a mask when tinting?
Should be nothing more than steam or water vapor.
Totally, unrelated. I was going to do an Optician Apprenticeship.... it was part time, I was hoping at least 30 hrs a week at $15 for 4 weeks (month)....
Then, I was told that it was 7 hrs times 3 days times 4 weeks at $15/hr.... there went my dreams. Down the drain. With that formula I would not even break even paying my rent, transportation, and bills.
And since I would be called whatever days.... I wouldn’t be able to get another part time.
Sorry but I'm not really sure what you are trying to convey here? Optician is the job that you make it. You can find part-time work or full-time work just like any other job. The hours requirements for going through the real USDOL apprentice program are set by them.
I am shocked that tinting tanks do not have thermostatic regulation of the temperature, rather than "1 to 5" heat settings. Even my Chinese hot-air frame warmer has temperature regulation & readout! There is no excuse for having a machine that boils over in a practice (I just learned why this happens!) Regarding wiping the lenses after tinting, they are softened by the heat. Were you using paper towels on the lenses? If so, that's too abrasive for plastic lenses. Another thing: plunging a hot lens into cold water subjects it to thermal shock which could lead to surface crazing (now or most commonly, later), especially if it's already edged or drilled. Your 1st rinse water should be at least warm, & let it set there for a minute. Then go to the cold water. Don't wipe until the lens is cool, & then only with lens cloth. Caution users to not allow the dye or hot water to dry on the lens (at 200 degrees, it takes only a few seconds for that to happen).
Regarding checking tints, do you have a visible transmission meter? That should be used EVERY TIME to get consistent results, not holding up to white paper or taking outside. (That might have been OK in the days when you were scoring & breaking glass lenses as the 1st step in edging). Also beware the UV treatment leaching out in the following tint step, causing lens to not meet UV specs. UV test again after tinting! To determine what patient wants, have tint standards that they can test (outside or whatever). Then you will know what % to tint to.
Reply to Brian Park, well Brian let me bring you back from your "shocked" reaction to Mr. Seegers presentation on -n-lab tint jobs. First of all,, he told you that he is not an expert one the matter, he's simply providing a demonstration on how we do tinting in our labs (some of us do) and also as a refresher for those that have never or it's been a while since doing so. Second, I've been doing this for 30+ years and let me tell you, there's thousands of similar tanks like that one in the video, in use everyday, with the company I work for. So, when you have been trained and done your 10,000 hours (and I do believe this rule applies to just about everything here) doing it, you don't need a temperature regulation device. Furthermore, I do my tinting jobs in a very similar way as Mr. Seegers explained above, and by "cold" water maybe he meant, regular room-temperature water, not iced-water. I have never ever had a broken lens doing it like he does. I do agree with you that he should have a light transmission and UV meter (reading) device handy, I do. Bottom line, and you should know this; there's no money to be made on tinting jobs, so if you think about ROI, it doesn't make sense -money-wise- to invest in equipment that is not essential.
+@@miggrodriguez9996 In the '70's, there was an excuse for non-regulated equipment, just as then, non regulated soldering irons were in widespread use for electronics assembly (and "skilled" assemblers never damaged components by overheating them, nor made "cold solder joints" either because of their "30 years + experience".) If this philosophy were applied to other aspects of your trade, you would be hand-edging lenses (those "expensive new-fangled numerically-controlled edgers" just not worth it!), starting with scoring and breaking with edging pliers.
Certain aspects of the trade require human skill (the result of the 30+ years experience) and others are better done automatically, such as heating oil to near or above the boiling point of water. This is yet another variable that an experienced practitioner need not worry about & focus their experience on other things that "count". For heater without regulation, there are many inexpensive add-ons (plug heater into controller, dip sensor into oil bath) available. For any one IN REGULAR BUSINESS, not doing this makes no sense. For a hobbyist who dyes 3 lenses in a year, at home, OK, I concede.
I (nor anyone else working in the trade) would not think of soldering circuit board with soldering iron without regulation. I consider irons without regulation "good for wood-burning pencils".
Regarding thermal shock, I was involved in materials science (regarding real fabrication, not academic wishful thinking). Optical plastics have several properties that make them susceptible. 1. POOR thermal conductivity. 2. LOW specific heat. 3. high TCE (thermal expansion coefficient). 4. HIGH rigidity (relative to other plastics, more like glass). 5. POOR tensile strength, & unlike metals, do not withstand tension applied over time). Unlike the tinting process itself, no specialized regulating equipment is required, and little labor is required either. Just some of that "30+ years experience" is needed to avoid thermal shock. A polariscope will verify. Heating a lens & then chilling it is similar to the process of "thermally tempering" glass lenses. Its purpose is to BUILD IN STRESS, which makes GLASS lenses more break-resistant (& you verify with polariscope & drop-ball test). You DO NOT want to build in stress into plastic! The polaricsope should show clear!
Lenses are tested for durability by dipping into boiling water & then cold water repeatedly (1 dip supposedly is equivalent to 1 month wear, according to one paper I read). Don't use up customer's lens life in the course of fabrication!
Yes it is done. You are responsible for third party 1_5 dials (Don't get 11). Get an infrared laser guided thermometer.@@bpark10001
