Anti-Glare coating on Glasses

[spiritof'76]

Wasn't sure where to post this........... but here goes

I have reading glasses and distance glasses that i use for primarily for driving, and as they are for driving i had them prescribed with an anti-glare coating.

This was fine when they were new but now a while later i can't seem to get the driving glasses perfectly clear they always seem misty, and yet my reading glasses have no such trouble so i'm assuming it's the coating that's giving the problem

Any glasses people had similar problems ?........ are these coatings just no good

Like Gaz, i have never had a problem with it either, and use cleaning wipes rather than anything else, especially if they are filthy. if it's just a bit misty, i'll use the glasses cloth they came with

What have you cleaned them with?

How old are they? My really old glasses got a bit grubby and I couldn't get them clear but that's when they were about 5 years old and so I was forced to get new ones.

Mine are 11 months old and I use the cloths provided by optitions to clean my glasses and I get the "mist" I have it now & it drives me mad!

Only way I found to get rid is use wet wipes which i have at work for wiping computer screens

I wash my specs under the tap with my fingers using either a non-moisturising soap or a minute amount of washing-up liquid. Rinse and dry with a soft cloth.

If you happen to have a pair of Ray-Bans then you should find that the cloth that came with them does a great job. They're certainly better than the cloths that Vision Express supply with specs.

I wouldn't be without anti-glare now, the reflections and glare would drive me mad. I've found with it though that the glasses are very sensitive to what you wipe them with. I never wipe them without cleaning fluid or at least rinsing them under a tap and drying them off with a good fluffy towel first. Then use one of the proper glasses cleaning cloths, occasionally I've found certain t-shirt materials can work but most of the time it just seems to smear them.

Just tried the baby wipe thing............... big improvement

Can only assume that the lenses were a bit greasy and the cloth in my case which is all i ever use was just pushing the grease around and not removing it !

Cheers all

^^^ best advice.

I've worn glasses for the past 23yrs and anti-reflective/anti-glare is an absolute must have, just wiping them to clean them always ends up smeary, or with some odd bloom type effect, especially with overhead lighting. A quick rinse to get any grit off, a tiny blob of fairy liquid and rub the lens between your fingers under the hot tap.

..if you get it right, with a thin column of hot water at the end, you don't even need to rub them to dry, as the water beads off completely.

Pentax K cloths, although they call them something slightly different now.

Difficult to find in shops now but you can get them here.

Have several and keep them where you can use the regularly. They have a little plastic case for putting them in. I keep a couple in my prescription sunglass case, one beside the bed and one on my desk.

Best way to clean your specs BY MILES, apart from the little blob of fairy liquid and some pretty hot water. Dry them with these cloths though.

I clean mine with soap and water too, and I used to use hot water, but on one pair the coating broke down. The optician changed them OK, but asked if I'd cleaned them with hot water and he said he could damage the coating.

Also don't use paper towels if you're cleaning them while out and about - they can scratch the lenses.

Ah, fair enough, not had a problem using hot water - sounds like reasonable advice though

Just use a weak soap and water, glasses naturally mist up after a few years, perhaps its time for a new set?

Try not to use washing up liquids as some of them will crazy some of the AR coatings.

Extreme heat can also cause the coatings to lift ie leaving them in a car window.

The newer anti reflection coatings are also oleophobic and hydrophobic. Worth the extra because the cleaning regime is generally reduced.
