Even if the flaw seems to be only cosmetic, light is scattered by the micro-fine scratches, which irritates the eye.

Can scratches be removed from a lens?

Unfortunately not. Lenses are not just one pane of glass or plastic, rather a complex system of layers for anti-reflection, tinting and other additional functions. Therefore “polishing out” scratches don’t work. Scratched glasses should be replaced soon. The micro-fine scratches cause light to scatter. The eye has to correct constantly which leads to fatigue. Headaches may be the consequence.
