Yes, the tint can be removed from polycarbonate lenses, but it's best done by a professional. It's a delicate process, so having an optician do it will help prevent any damage to the lenses.
The darkest sunglasses are typically made with lenses that have a very high level of tint or are polarized. Sunglasses with polarized lenses are designed to reduce glare and block more light than regular tinted lenses, providing maximum protection from bright sunlight.
The index of refraction varies for different colors of light (i.e., for different wavelengths or frequencies), therefore, a source of white light, like rays from the Sun, can get separated into their components. White light isn't "pure" (monochromatic) light - it is really a mixture of many different colors.
The lenses are made from either glass or plastic. The frames are generally made from plastic, nylon, a metal or metal alloy.

I spray painted my car and noticed over-spray on my polycarbonate eyeglass lenses the next morning. I tried soap and water but that removed none of the paint specks. I called my optometrist and they warned against using any solvent like paint remover or acetone on polycarbonate lenses. It would be OK on glass lenses, but i think polycarbonate is a plastic. So I tried 70% rubbing alcohol and some lens paper and with a little rubbing the paint specks came off. I quickly rinsed the lenses with water to remove the alcohol residue. The optometrist's office said it is not a good idea to let any substance besides water soak into the lenses as it may make them more brittle.
