My 3 year old titanium glasses are in very good condition. The frames are very sturdy and my prescription has not changed.

These are polycarbonate lenses.

The only thing wrong is the anti-reflective (AR) coating...it is flaking off and impairing the quality of vision.

I am eligible to get a new pair of glasses with only a $20 copay. I can get a new pair, and make my old ones a spare. Or I can get prescription sunglasses. I also wear contacts a few days a week, so I do not wear glasses every day.

I would like to save these glasses. The optometrist's office said the AR coating can not be removed, that the lenses have to be replaced. (Also newer lenses now have AR embedded in them, eliminating the annoying flaking off problem.)

I searched the web for homegrown ideas for dealing with this problem (hey, I have nothing to lose), and found someone had success polishing their lenses with sunscreen.

Does anyone know of a way to rid my lenses of deteriorating AR coating?

polycarbonate = plastic.

You could try a plastic cleaning/polishing product made for automtive/marine use - like Novus or Plastix. They're really for removing haze and scratches from headlight lenses, plastic windows in convertibles, etc. But they might also remove the coating that you're dealing with. I'd probably try novus 2 if anything, here's their website: www.novuspolish.com

I have no idea how it compares to novus 2, but toothpaste is a fairly fine and mild abrasive that you can try for free. I have successfully used it around the house for various small polishing jobs.

If they are three years old, it's possible that you might need to update the prescription anyway. What would it cost to just replace the lenses without any add ons, out of pocket?

Check you insurance coverage. My coverage is two years for frames, but more frequent for lens only. I would seriously consider getting new frames and keeping these as a spare, but I don't use contacts and although I can legally drive without glasses I don't feel comfortable doing so.

I'm going to go back on my own recommendation. I was checking the replies, and clicked on the mfr link I posted earlier. Found this nugget in there:

NOVUS No. 2 and No. 3 Polishes are not recommended for use on coated plastics or eyeglass lenses.

Nope. I just had my eyes examined, and my vision has not changed.

I am eligible for new frames and lenses this year, and plan to keep my old ones as a spare. I would just like to get the coating off of them so I can see through them better.

If I could "clean 'em up", I would consider keeping my old pair as primary, and using my insurance benefit to purchase prescription sunglasses.

Any chemists out there who want to take a stab at this?

Perhaps they say that because it removes the coating.

There are a lot of different types of plastics out there. What may make a good cleaner for one kind could etch or pit another. Some plastics melt when exposed to acetone and others just get clean. At work one day I melted my cheap digital watch when a spray of acetone got it. :\

Try ask.com for a lot of links to pages with things you may try:

I'd vote for having the lenses replaced at Costco or some other inexpensive optical shop.

Thanks.

I already checked with Costco and they will only replace lenses in frames they originally sold.

I'm in the same boat with the flaking anti-glare coating, and it's driving me nuts. I think I need a new prescription so I'll probably get some new glasses and put new lenses in the current frames, but so help me I'll never get anti-glare coating again. I'll have to ask about the embedded option though.

Lucky! I have to get mine changed every 2 to 3 years. My eye doctor says that hopefully this will slow down as I get older. The prescription I have in my current glasses (got them 6 months ago) is so different that if I slip on the other pair with the last scrip (from 4 years ago) I get dizzy.

I got the anti-glare coating on these, and it's very distracting. If there is a light behind me, I see shimmers of purple from the coating in the sides of the lenses. I won't get it again.

I'd probably do the same thing - get a new pair, keep the old ones as a spare - or for any time you're doing stuff like painting a ceiling.
