Can I make the tinted lenses lighter without replacing the lens?

[Seaboard]

My sunglass lens is in gradient blue color. it is too dark. Can I make them lighter without replacing the lens? If so, where can I do it?

You can put them into the alcohol to heat them up. You must pay attention to them to see whether there are some changes for the tint color.

If the gradient color is in a coating, not in the lens, you may probably change the color. Try to take them to the optical store and ask. Maybe there are some chemical material that can remove it and make the lens retinted.
