Polarized. Polarized lenses cut reflected glare—when sunlight bounces off smooth surfaces like pavement or water. These can be especially helpful when driving, boating or out in the snow. Polarization is unrelated to UV protection, so you still need to ensure UV absorption of the lenses. Polarization also uses a screen-type mesh to block certain wavelengths. That is why using Polarized lenses to look at digital devices causes a shadow right in the center of your vision.
