A co-worker of mine took the ABO test on Sunday. She was surprised by the number of questions regarding glass lenses. Yes, we work for a chain optical that has all but phased out glass lenses years back.
She asked me whether I thought glass was being "phased out" in the industry or just in particular chain opticals. I told her I would ask on Optiboard to satisfy our curiousity.
What percentage of eyewear is glass/crown or photochromic? What about CR-39 ? Hi-Index (like spectralite) or 1.67 ? Poly ? Trivex ?
Just curious ...
Thanks -
Karen :cheers:
