So I've reached the point in my career where I'm starting to see people come back with two-to-four year old glasses, and a common complaint I'm getting is that the lenses seem to smudge and retain dirt easier than on dispense. The majority of these are Recharge, and some EX3s. I know I've run down Hoya on the boards, but, the quality of their ARs was never one of my many issues. Help a relative noob out-- is it normal for an AR to lose its' oleophobic properties after that period of time, or is this just another reason for me to hate on the big H? Is there something in particular that causes a breakdown-- heat, improper cleaning, etc.-- that I could advise patients to avoid? Has anyone encountered another AR whose oleophobic properties have a longer shelf-life?
