Removing gorilla glue from glasses

[Werewolf]

I havn't had any for a long time.

I've got a feeling they generally stopped doing them in the 80's or early 90's, plastic lenses are much easier to manufacturer, are lighter, cheaper and easier to stock.

IIRC plastic lenses are basically injection moulded to a preset value for the prescription (so the factory might have thousands of each value as a lens blank), then cut to fit the chosen frame and given a final polish, glass lenses had have a lot more processing between the initial blank and final fitting and were far more likely to fail at various points in the process.
I think there is also an element of they can affect the correct value by using different plastics so you can get a higher change in a thinner (thus lighter) lens.

Easiest way would be to visit an optician, and once he's stopped laughing order some new specs.

Opticians may well be able to just sort it out as well. And many of them will do it for free.

yeah dont try any of those solvents - you will likely dissolve the plastic or at least take off a coating.

I know you’ve all been waiting patiently for an update, brought new specs in the end after much deliberation.

Thanks for all of the suggestions but I think they are a lost cause.

Probably for the best. I'm going for an eye test tomorrow, 2 years late. I always get new frames though when I get new lenses.
