Anyone who has alot of knowledge in labwork, etc., I have a question for you.
Why is it that so many lenses come back from the lab with scratches?
A customer called today (she picked up her glasses yesterday) and said that although the scratches do not seem to obstruct her vision, when she holds the glasses in one of the full-spectrum natural lights that she has at her desk, she sees all kinds of scratches that look like someone took a cloth and was cleaning the lenses...making scratches with every circular swipe.
Is it possible that some scratches do not affect the lens and vision? I would like input and opinions on what type of scratches are acceptable and what type warrant a return visit to the lab.
I know from personal experience that after a couple of years with a pair of glasses, they begin to scratch and the scratches do affect my vision when I look into the sun or a light.
Thanks.
p.s. I think this is a major problem, I have worked at more than one optical shop and it is rare to get lenses back from the lab in perfect condition.
