Back in the day 45 or so years ago I learned how to take small scratches out of glass (eyeglasses or watch crystals)  using a paste of toothpowder from my dad, but we never covered if there is a way to do something similar to plastic eyeglass lenses.

Does anyone have any ideas or tips how to remove fine scratches  from plastic eyeglass lenses without ruining them/hazing them?

Not on eyeglasses but I've used Mother's Mag and Aluminum polish on plastic and my vehicles plastic headlight lenses.  Also, have heard of people using it on watch crystals.

If there is an anti-glare or scratch resistant coating I'd be hesitant to use. 

It might be worth a try on a piece test plastic.

I still have my old glasses which can be used as a test bed.

My only concern is related specifically to eyeglasses. The geometry and clarity of a Dial Indicator is not absolutely critical, lenses for your glasses is another story.

Mothers is fine, although I typically use 3M products when possible. Mother's vs Meguiar's is essentially the Ford vs Chevy of the car detailing world. Both companies tend to sell their version of California Special Sauce, and their product descriptions can be entirely too vague at times. 3M on the other hand tends to be in the business of selling Fucking Chemicals and their products tend to be labeled accordingly.

Anyway, opinion: If I was dead set on polish, then the Mothers mag/aluminum polish (or something similar, in the 2000 - 3000 range) would probably be a starting point. I'd probably then consider going over it again with a finer compound.

The problem, in general, with polishing is that you're supposed to start with a compound that has an abrasive roughly the same size as the scratch itself and work your way up. In reality, to make that scratch fuck off entirely from polishing, you're going to fundamentally alter the geometry of the lens.

There is allegedly an alternative out there that I looked into 5+ years ago. I don't know what it is called or how to find it, but I recall seeing something that was essentially Bondo for glasses. You clean the lens, apply the compound to fill the scratch, and then buff out any excess. It could be too good to be true, I don't know as we didn't end up going that route.

Mark- Another good brand is Novus. It is available in fine and medium grades of polish. Fast SS gave you a good analysis. A deep scratch cannot be removed without sanding. This will probably destroy an optical quality lens. Try the method on the video.  I am in the Meguiar's  camp and they offer two grits of plastic polish, too.  In any case, it will be better than what you have now

Thanks, brother.  The scratch I have now is extremely fine. I can’t see it looking thru my glasses. I only see it when holding them up to light to check how clean I’ve gotten the lenses. It’s just annoying because they’re very new and I’ve been very careful with them so far.

Many years ago (like 30+), I was at a plastic model kit contest. One of the vendors had a polishing compound made in Germany. I've used it over the years for taking scratches out of various things from polystyrene canopies to sunglasses and such. works awesomely.

I wish  that I could remember the name of it. I have it buried somewhere. I'll try and find it and put it up here.

While I understand the desire to be self sufficient...

Have you thought about going back to the shop that made the glasses?

I had a pair of glasses (prescription sun glasses) that had been made at LensCrafters that caught a swipe from a weedeater and got scratched. They popped the lenses out, threw them on the machine, re-tinted them and handed them back to me in about 15 mins good as new. I think it cost me 10 bucks a dozen-ish years ago.

That thought did occur to me David, but my glasses are from Costco and they don’t have internal lens making facilities. So self-sufficiency reigns supreme for me.
