My mother had a problem with AR coating wearing off on her lenses, leaving them hazy. She couldn't see through the lenses even after carefully cleaning them with lens cleaner and cloth.
When she had her glasses made, she paid extra for the AR coating, was given some sort of a warranty on the coating, and told that she had to purchase and use the optician's branded lens cleaner to maintain the warranty. She did just that. However, her lenses started going hazy after about a year. When I looked closely at them, I could see the coating had worn off in spots. She returned to the shop where she purchased the glasses (I think it was one of those "glasses in an hour" places) and asked that the coating be reapplied, that the lenses be replaced or that her money be refunded. She had the receipt that showed both the purchase of the glasses and the optician's branded lens cleaner. The optician would do nothing for her. Told her that the AR coating <i>could not</i> be reapplied, wouldn't replace the lenses, and only offered her a discount on her next pair. She left the shop and never patronized them again. She paid a lot for those glasses, and I think she should have taken them to small claims court. I've begun to regard it as a built-in "obsolescence factor" that opticians push, a way to ensure that glasses only last for a short period of time before they need to be replaced. Because of the bad experience she had, I refuse AR coatings on my lenses. R.
