Pro Tip - Are polarized sunglasses better? Are they worth the price?

In many cases, yes. All sunglasses reduce brightness and block some amount of harmful UV rays. However, only polarized sunglasses are scientifically constructed to eliminate glare. Not just reduce it, but eliminate it. Fully polarized sunglasses reduce eye strain and help you see better around water, snow, sand or any other reflective surroundings.
