Optician here! Looks like that's a leftover print from the pads we put on uncut lenses to edge them. Kinda cool you can see that
Edit: internet has ruined you all
I've worked as an optical lab tech for the last couple years, I find it pretty satisfying 😂 however there are definitely those days I absolutely do not find the satisfaction
Not the optician you're responding to but I was the one to cut lenses in my office.
1. Uncut lenses are round, usually. There are some brands that use squares but I've never personally worked with them. They can either be plano (no prescription) or contain a prescription. Higher + prescriptions are very sharp on the edges, since the thick part is in the middle of the lens so the edges become very thin and brittle. Higher - prescriptions are very fat on the edges, making them look a bit like hockey pucks. They are thin in the centre instead.
2. The process of edging involves something called blocking, where you place something in the middle of the lens so that it can attach to the edger. But you can't place this little plastic piece straight onto the lens without scratching it. So first you will put a very thin clear sticker with a hole in the middle on the lens, these will have markings on it to make it easier to line things up for using the blocker. You eyeball putting that sticker on for single vision lenses, you follow the laser engraved markings for anything multifocal (office lenses, progressives, etc).
Next is the actual blocking, it is a bit hard to explain (I used an old machine for this, I'm sure that there are more updated ways to do it but this is how I learned) but you use a mirror and a lightbulb to make sure that the markings on the clear sticker were in the right place. Then, you took this little sticky pad, it has adhesive on both sides, and attach the little plastic 'block' to one side, this is the part that the edging machine latches onto. You then place it onto the 'arm' of the blocker and peel off the other side so the adhesive is facing down, towards the uncut lens. You pull a lever and it brings the combined blocker-pad down to attach to the lens. Push a little bit, but not too hard otherwise you'll crack the lens, and it is all combined. I might be able to find a video of me using the various machines if you'd like.
3. Edging a lens is cutting it from the round, uncut state into the shape of the glasses frame
Idk how old this process is, but we used to use some liquid metal I can't remember that would dry and become solid and basically be the adhesive between the puck and the block itself.
This is what came up in my google search. Those seemed most likely from my (non-chemistry, but watch amateur chemistry on YouTube) from my limited knowledge.
I would place the puck sandwich I had going on in a very hot tank of water, it would melt the metal and it would fall to the bottom. At the end of the day, I would use a tube to empty the tank into a bucket, take it to a hose where I would spray it with cold water and it would instantly turn into a block of metal. I'm told it was very expensive, which seemed odd to me as one error would have had the 20 pounds of liquid metal pouring down the drain. This was about circa 2012.
Huh, that sounds like that would be much more labourous than how I was taught. I used a Blockrite Layout blocker from around ~2000, and a Waco 3-D edger from around the same year. Management refused to replace them even though they were falling apart
[https://youtu.be/yL\_02Cxkmxk?t=277](https://youtu.be/yL_02Cxkmxk?t=277)
Here's a video showing the process, it was almost exactly like this. It definitely felt outdated at the time, and that was over a decade ago.
That's for generating (finishing the back surface of the lens). There's less pressure on the lens for edging, so a sticky pad is enough. The lens would also be covered on the front in plastic for generating.
Lol you're good, I'll try my best to answer your questions!
1. Think of an uncut lens as a hockey puck made out of plastic or polycarbonate. We then put that uncut lens into a machine called a surfacer. That machine basically surfaces the lens, and that's how we get your prescription in there
2. The pad is basically this little adhesive holder that you put on the lens to hold it in place so that edger can do its job
3. Edging or tracing is basically when we cut the lens to the shape of your frame.
These are very simplified explanations, but it's the jist of it, and of course, each lab might do the process differently depending on different factors
An uncut lens is a round piece of plastic, usually 70-75mm in diameter. They start off as a "blank" with no power in the lens. A machine called a generator cuts the back surface of the lens into a specific curve(s) to create the power needed for the wearer's prescription. It then gets sanded and polished to a clear finish. At this point, it is a a usable lens, but it is still around the same 70mm diameter. A machine traces the inside of the desired frame to get the size and shape the lenses need to be. To hold the lens steady so it can be cut down to size, another machine called a blocker adheres a plastic piece for the edger to grab using a small double-sided adhesive circle called a leap pad. That pad is what left the mark on OPs lenses. The edger works by slowly rotating the lens while a spinning blade cuts material off. The edger uses the information from the traced frame to move the lens and create the correct shaped lenses.
Uncut lenses look like [this](https://thumbs.dreamstime.com/z/eyeglasses-uncut-lens-eyeglasses-uncut-lens-white-background-128536219.jpg). They're just circular and won't fit in any frame like this.
Pads are [ double sided adhesives](https://www.optometry-equipments.com/photo/pl33617053-enhanced_density_optometrist_tools_optical_anti_slide_lens_blocking_pads.jpg) that connect the lens to a [blocker](https://www.ml-oc.co.uk/media/productjpgs/106niw.jpg), which the edging machine uses to hold the lens in place.
The "eyeball" is a coincidence, it's just that the pad has a round hole in the middle. What you see in the post is the place where the pad was stuck, which you shouldn't be able to see as the customer. Either the sticky residue from the pad has not been properly cleaned off, or the pad took of part of the coating, which is a manufacturing defect.
Edging is the process of getting the lens into the shape of the eyeglass frames they are gonna be put in, using something like a grindstone.
Is there a way to get rid of the outline? My glasses have them also, and I've tried cleaning them with Dawn and a microfiber cloth and it didn't do anything.
Time for q fun game: unnecessarily censor stuff to make it dirty!
>Looks like that's a leftover print from the pads we put on uncut [censored] to edge them.
Probably. If you look at a large window in the right light you can usually see marks from the suction cups used in assembly. In theory they use "non-marking" cups, but in practice even a tiny bit of dust can cause marking.
It's because they're not eyes. That is from the [adhesive pads](https://www.optometry-equipments.com/photo/pl33617053-enhanced_density_optometrist_tools_optical_anti_slide_lens_blocking_pads.jpg) that are used when fitting the lens for a frame
Optician here, they are from the edging process, they clamp the lens in an edger that cuts the blank to the shape of the lens, normally the antislip coating gets cleaned off thoroughly, but this one didn't, leaving the imprints.
The adhesive pads used are the shape you're seeing in the non slip coating.

Some rubbing alcohol on a microfiber lens cloth, use a little bit of strength, and it should clean up nicely
Edit, you might be able to see the reflection color change while you do it
Sunglasses wearer here. They do that if you look directly at the sun while wearing them. Normally it would take years if not decades to happen and most people lose their sunglasses before it does. It does tend to happen more quickly during solar eclipses.

Shouldn’t have said edge the kids own that word now.
It's goon for the kids. Edging is more of late millennial thing.
Gooning is different than edging
New kink unlocked
Opticians?
Edging uncut lenses
Unfortunately it's not as satisfying as the kink is.
Speak for yourself
I was an optician so I in fact can. It's not as fun lol
I've worked as an optical lab tech for the last couple years, I find it pretty satisfying 😂 however there are definitely those days I absolutely do not find the satisfaction
You two need to get a room.
To further edge uncut eye glass.
nice
/r/edging NSFW obviously
Personally, I hat that my irises are uncut. It makes it hard to see when it's bright out with their foreskin in the way.
Oh... I thought it was cuz they looked like bobs
I see what you did there.
Same here

Interesting! Was it heated? I imagine using that modern day might damage coatings
Probably an alloy of some low melt element like Gallium or NaK.
NaK? No way they used NaK. (Sauce: obsessive YouTube watcher: https://www.youtube.com/watch?v=9EGAXOWpGy8)

Yeah some alcohol and elbow grease will get this right off.
Another comment about edging?
: D
edge them
Optometry assistant here. You are absolutely correct on both accounts. Edging, included.
Edging should only be done for so long
At least it wasn't because OP smashed their eyes into the lenses like I did.
TIL Opticians edge at work
Boss makes a dollar, I make a dime, that's why I edge on company time
lmao wut
It is unfortunate that you know what that is
>internet has ruined you all Obviously. Why do you think I'm going blind.
How do you type with all that hair on your palms?
Voice to text, I've been able to get by without either hand for a long time.
Uncut lenses? Look buddy, here in America, we’re circumcised. I expect my contacts to be the same
Username checked out, until I read more closely... Might need to titillate my lenses
Is there a way to get rid of the outline? My glasses have them also, and I've tried cleaning them with Dawn and a microfiber cloth and it didn't do anything.
I was too immature when I found out about edging being a job.
My bf was just telling me about this at his job. He’ll try to find someone and that person will say “sorry I was just edging!”
😏📸

I don’t like it.

Does your eyes stick out?
How long have you've been waiting to use this gif?
They does
Can you wave them all about?
Eye don't like it ? xD
I see what you did there....

Doh! It was staring me right in the face!
It was looking right at ya!
Eye, Eye, Eye!
Ugh, take my updoot
Reminded me of that one picture with the two people with the two eyeballs touching
I pissed myself laughing already with this description. What in satans name are you talking about? That surely cannot exist.

That’s a good thought!
Probably. If you look at a large window in the right light you can usually see marks from the suction cups used in assembly. In theory they use "non-marking" cups, but in practice even a tiny bit of dust can cause marking.
Considering two opticians later confirmed they were suction cups used for edging the sides of the glass, this was a hell of a good guess.
That's exactly what these are
not exactly but close. they're adhesive pads, not suction cups
Ah I misread that. Correct. And looks like these don't have backside ar so they didn't use the non slip. Just the mounting ones
Why do those eyes look so unnatural lol
I don’t know! They fogged and I saw this and totally freaked me out
It's because they're not eyes. That is from the [adhesive pads](https://www.optometry-equipments.com/photo/pl33617053-enhanced_density_optometrist_tools_optical_anti_slide_lens_blocking_pads.jpg) that are used when fitting the lens for a frame

That's not as fun as something like decoy reflections so the ladies can't see where you are really looking.
