Are you sure that's not just a clear plastic protective coating for shopping?
Not that I'm aware?
Those are interesting.
I just got glasses for the first time a couple of weeks ago and I was really looking forward to shooting with them but the top of the frames are in the way. I was pissed off!
Let us know how they work.

I'm not sure?

I just received mine today. What do you do about the yellow markings?
Why don't you ask the outfit you bought them from?
Yes, they are from Canada. I can't call them till Monday because they just arrived. Too late.
edit: I tried soap and water. No luck.

It kinda looks like a template for 'grinding' for your perscription. It appears that the upper markings are for your normal viewing axis and the dashes may be for the beginning of close-up vision. They are progressive lenses, right? I would imagine that it definitely comes off!
They are very interesting looking glasses, though. Let us know how they work when you have it ironed out BTW, also where you got them and at what cost.
Thanks

I use to work for a company that ground glass lenses for sunglasses. They were high end glasses; Revo, Ray Ban, etc.. Ok, so I know a little, but not a lot about the prescription glasses world. I'll hazard a guess, but that's all it is. The machines I was working with took a cam that described the shape and used it not unlike a key machine to cut the shape. The blank you put in was round and much it would get ground off.
That was sunglasses. For bifocals, I'm guessing they can't do that as you would have to worry about getting the prescription portions horizontal, so I'm guessing they instead take an unmagnefied blank, like with the sunglasses, cut it to fit the glasses, mound them and then mark them to show horizontal lines so it's ready to have the prescription ground. The frameless top of the frames you've got support that theory as they would be more concerned that the shape forming portion of making the lens was perfect as is not necessarily so important with frames you push the lens into as they surround (and hide) the outside of the lens.
Hope that helps. Again, just a guess.

Yes, they are progressive. I got them from billiard-eyeglasses . com . (leave out the spaces)
They were a little over 300 with all the bells and whistles.
Lol your optician was just too lazy to remove the markings.usually we remoive them prior to deliver the glasses. That's. not professionnal IMHO for them to have sent the glasses without the cleaning.
It's'a special ink. Use aceton, carefully, to remove this ink.
Thoses marks are normalized. they're used to control the values of the lenses, and they identify accuratly the référence center of the progressive lens.
If aceton don't work, use white spirit. (Depends of the brand of the progressive lenses)

I'm not sure if I should just scrape it off and go with it, or not?
It comes off pretty easily with a fingernail.
I don't think I would scratch them that way?
I hate to wait till Monday when I could be using them tonight!
It would have been nice if they put some kind of instructions in with them!
LOL. Them are some of the wildest glasses I have seen. Maybe from the future,,,a proto type and accidentally sent to you.
They could be the key to the universe,,,I seen it on transformers!!!:rotflmao1:
But really I have never seen glasses like this before. And do not wear them. Is the idea to get the frames out of line of sight??
