Anyone know how to remove super glue off Prescription glasses
Have you tried taking them to your optometrist? They may have a safe method.
Here are some products made just for that purpose.
Finger nail polish remover.
It's an old trick.
What you use probably depends on whether it is on the frame or a lens, what that spot is made of, and of on a lens whether you have any kind of coating on the lens. I would go to my optometrist’s office and talk to the optician.
