I would try jewellers rouge; but preferably get new glasses you can't afford to mess about with your eyesight especially for the likes of we modellers where we need the best we can have. I have just bought 2 new pair of varifocals as my recent eye test showed a deterioration & the need for new lenses; not cheap!

What about the coating, if any?

Hi Alan,

Sorry to hear about the frosted zone on your glasses. Do you know if the material used is optical glass or some kind of plastic with a hard coating? The lenses in my glasses are made from some kind of plastic material with a thin hard coating on the surface. I would first try polishing on a part of the lens that is little used to see what happens.

Not saying it's the cause here but I;ve been guilty in the past for putting specs down on their lenses as th casue for such damage. It depends how old they are/when you last had an eye check as to whether still appropriate prescription.
Another option may be to fit cheapo flip up clip on mag lenses to a non-redaing pair as a conversion.

Also worth considering when having an eye test making sure you have a copy prescription and ordering a second pair (perhaps on-line cheapos) for use in dirty environments such as the shed…

Be careful not to take off too much and change the optical properties, I had a tiny scratch on the car windscreen which I had professionally polished out, it looked excellent afterwards but when a cars image filled the polished area it looked all distorted, I had to replace the screen.

Toothpaste will act as a fine polishing compound on plastic.
