It is generally not possible to repair scratches to glass or plastic lenses of eyeglasses. It is sometimes possible to polish or smooth small, superficial scratches, but any method that changes the thickness of the lens can affect its refractive ability, which changes its prescription strength.

Most lenses have some type of anti-glare or scratch-resistant coating that makes it more difficult to repair scratches. Home remedies and products that claim to repair scratched lenses usually act as fillers that reduce the appearance of some scratches, but these solutions are temporary fixes that require repeated applications and often leave behind some film or residue that interferes with the coating on the lens.
