START BY PUTTING YOUR SUNGLASSES ON AND STARE DIRE

To know if you are wearing polarized sunglasses, start by putting your sunglasses on and stare directly at a shiny surface. If your lenses are polarized, you should be able to look at the surface for a long period without squinting or feeling discomfort. If you can sense the glare, then your sunglasses are just tinted with a darker colour. Polarized sunglasses should be able to eliminate glare as well as haze. If your sunglasses are polarized, you can also experience sharper vision with the surrounding objects appearing in greater details.
