- How to get good, accurate, consistent boxing system measurements. The boxing system is used to measure eyeglass frames and lenses for sizing and finishing layout work. The primary boxing system measurements are the frame A, B, & DBL. The common frame sizing numbers like, 56-18 are determined using the boxing system. Accurate frame measurements are important for finishing work. Learn More: opticianworks.com/
Accurate frame measurements are important for finishing work. Opticians use the boxing system to size a frame for individual wearers. Opticians use the boxing system to measure frames to calculate lens decentration for optical finishing work or optical finishing layout. Other boxing system measurements include segment height or seg height, segment drop or seg drop and the geometric center of eyewire openings. Opticians use the boxing system as part of their daily work.

What program did you start? And don''t miss the website! www.opticianworks.com
@@LaramyKOptical im in the optical science-eyeglasses program in NAIT and no i haven't checked out the site but will right now!
Love your videos. I am an Eye Care Specialist student and when I don't understand something we went over in class, I watch your videos and it all makes sense.
Great to hear, Gabriella. Thanks for watching!
your chanel is amazing. im a qualified Dispensing Optician an i must say i watched almost all your vids. im from cape town!
Thanks Nicki!
Thanks for amazing videos I am an optical lab technician always refresh my optical knowledge with your fantastic videos keep it up 👍
I am attending Penn foster optician course and also using you videos as well to try to get a better under standing. so far so good with the video.. now I only problem is retaining information..
You do not need Penn Foster course. These video and some good text books is all that is sufficient.
which book
it's hard to find a good teaching video for this. which I'm really grateful to found your channel. please keep inspring people. please keep give us students a good information so we can improve for future. thanks
You are welcome!

Great ℹ️
Thanks sir🙏👍
Thanks a lot

Hi John,
I have a question. (Disclaimer: I'm not an optician, just someone trying to get a decent pair of glasses for my Dad.)
I was doing some searching and reading about UV400, and an article on the Laramy-K website named "The Problem with UV400 Treatments" came up on Google. That article was written in 2010, which was a long time ago. Do you know if it's still the case that the UV400 treatments used on most lenses lose their effectiveness fairly quickly, or if things have changed for the better since then?
I know you didn't write that particular article, but I wondered if you or anyone at your lab could shed some light on this topic. Many thanks if you can answer.
Yeah No,
All are welcome here.
UV400 dip coatings are primarily used on CR-39 or the original plastic used for lenses.
Most glasses today use other materials that have good UV protection built into the lens.
A good AR or non-glare coating can also add additional UV protection.
It comes down to material and how much UV exposure he might be getting in daily life.
When outdoors one should be wearing a good pair of sunglasses!
Otherwise IMO any good lens and AR coating should provide all he needs for ordinary daily living.

Hello Mr. Seegers.
I'm having some trouble when getting A, B, and C measurements. My issue has to do with the placement of the PD ruler on the lens' front surface, due to its curvature. When I rest the PD ruler on the lens' surface, is it supposed to rest flat on the middle of the lens or do I press the 0mm mark against the edge of the lens and follow it until the other edge, all the while flattening the ruler as I go?
Assuming a plastic PD stick with some give I would lay the wider flat side against the lens for stability and use my thumbs nasally and temporally. Don't make yourself crazy about it... The only time 0.5mm will matter is if you are trying to get the absolutely thinnest possible plus lens in surfaced.
What I learned: a PD stick is a metric ruler showing mms.
Thanks! You're awsome!
Thanks for watching, Adam. :) You're awesome too!
Why, thank you!
Grande thank you
You are welcome.
Awesome video
Thank you very much for your help to understand the boxing system; but how I can get the ED without ruler?
You can't. But I'm guessing you mean how do people just "know" the ED from the frame measurements shown or stamped on the frame. A rule of thumb can be A + 2 but that only works (some of the time) for simple shapes and smaller to mid-sized frames. So for a 52/19 you might guess of an ED of 54. Won't matter much until you are trying get the thinnest possible lens in plus powers.
Sir your explanation is very easy.
I want know sir , how we give segment drop in bifocal
In the US segment "drop" is the distance from half the frame "B" and the top of the segment. It is another way set height can be written. X # mm below half the B or X # mm above the lowest point in frame eyewire opening. John
Can u tell me what is abo and give further details
I'm thinking about taking the ABO soon how can you guys help me to prepare for it
Go to the Laramy-K CZcams page and watch the video, How To Pass The ABO!

Laramy-K Optical Thank you so much
Thanks for watching!
Comments about boxing system: you cannot always read the A and B directly from the frame! For example, for a slanted oval, the A and B must be read from the boundaries of the box. Because the oval is slanted, there is no place to measure. You must construct the box, and then measure the box. That is the whole principle of the "boxing system"
You also comment where the "edge" of the lens is. For a lens fitted in a grooved frame (usually most plastic and full-rim metal frames), the box is tangent to the flat part of the lens edge, not counting the protruding part. For grooved lenses (in half-frames using nylon cord), the boundary of the lens is the flat edge, not the groove.
Please comment on the details of this! Do frame tracers trace the groove or the flat surface outside the groove? Another measurement is lens circumference. Is that measured over the protruding groove, or over the flat part of the lens edge?
Brian,
If you have a different way of doing anything I show then by all means use it. As long as you get good consistent results - that is all we are ever after.
John
Sir please suggest me your video for blending of progressive lens and design of progressive lens
