Dark tint and UV protection are not the same thing. Good sunglasses should provide appropriate UV protection as well as comfortable visible-light reduction.
What Is UV Protection?
UV protection refers to reducing ultraviolet radiation reaching the eyes through the lens.
Does a Darker Lens Mean Better UV Protection?
No. Tint darkness mainly affects visible light. UV performance depends on the lens material and treatment.
Polarised vs UV Protection
Polarisation reduces certain reflected glare, while UV protection addresses ultraviolet radiation. They are different features.
Prescription Sunglasses
Many prescriptions can be made as sunglasses, depending on lens design, frame and available options.
