Polishing scratches from glasses ?

[Blade]

My Bolle Edge 2 cycling glasses are about 12 years old now and as far as I know spares are not supported any more.

They are the type of glasses with a prescription insert and an interchangeable plastic front shield in various tints.

The clear front shield has a few minor scratches on it, which I would like to polish out if possible.

The internet suggests all sorts of things from toothpaste to Brasso, but I'm reluctant to try anything unproven in case I wreck my glasses.

Has anybody had any practical experience of polishing out scratches in plastic? If so, how successful was it ?

I have successfully polished out scratches in a plastic bike light with Solvol Autosol metal polish.

I will try it with an old pair of sunglasses.

I've polished out scratches with toothpaste.

Try at your own risk.

UPDATE (Autosol on sunglasses):  I don't think it's done any harm, but it hasn't done any good either

'Polywatch' used by jewellers to polish out scratches on watch crystals. Works a treat!

T-cut and elbow grease.

Seconded, also works for those who when they get a puncture  turn their bikes upside down and stand bike on the saddle and bars, then realise they have scratched their computer

More expensive lenses may have anti reflective coats etc that might get damaged. I brought my Rudy's along when buying some new contacts and had my optician do it for free!

Brasso works on the clear lenses of goggles (ski goggles, or full-face helmet goggles.  I know this because my son uses it to reduce the amount of "fogging" on his goggles caused by wipping them with a dirty glove 

Obviously it will also remove any coating that is on the lense, but it certainly polishes out scratches.

Micromesh is your friend. There is Supplier in the UK I believe.

I have used it to polish my guitar after some damage repair and it is superb. Grades go up to about 4000 and they sell various repair kits. I imagine their counter top kit would solve your problem.
