Hey there,
I have been getting some lenses coming back from patients that are photochromatic (unknown brand to me as my lab supplier surfaces them and I get them in a sleeve to finish) and they are starting to maintain a yellow tint. Some are over a year old and some are not.
I think it is the quality of the lens and want a different product but they mentioned something about them oxidizing over time. Ideas? Suggestions? Have any of you dealt with this before?
Help! Thanks in advance. :)
