Both these things can improve night vision and improve vision for driving during the night. However, polarized lenses are excellent for water sports where glare from the water can be quite a nuisance or perhaps a nightmare. Also, as noted above, while polarized lenses can protect your eyes from UV light, the quantity of protection varies. Be sure you check labeling for specific UV protection claims. When ordering your next pair of prescription sunglasses, you might see the option to include an anti-reflective coating.

Polarized lenses are primarily for outdoor use and are used to glare from smooth surfaces.

Where n0 and nS will be the refractive indices of the first and second media respectively. The value of R varies from 0 to 1 1 and is usually quoted as a share. Complementary to R may be the transmission coefficient, or transmittance, T. If absorption and scattering are neglected, then the value T is always 1 − R.

This could be observed when looking by way of a window, for instance, in which a reflection from the front and back surfaces of the window glass can be seen. The effectiveness of the reflection depends on the ratio of the refractive indices of both media, along with
