How to tell if lenses are polarized Just through your phone ?


As long as we're in the summer season, it's important that we use sunglasses to protect our eyes from harmful rays, so today we'll talk about the best glasses you can get and how do you know if they're worth it or not.

We're talking about polarized glasses, known as polarized sunglasses, which have an additional filter in the lenses, eliminating glare from horizontal surfaces such as water,  roads, etc. Do not allow light to enter from certain angles only, and it prevents blinding glare. Polarized lenses also make it difficult to read LCD screens like a smartphone, and should not be used for those who need to look at LCD screens frequently.

When wearing sunglasses without polarization, lenses only reduce the amount of light that travels through the lens horizontally and vertically. If you choose polarized lenses, the glasses absorb horizontal light waves, while allowing vertical waves to pass. Light basically moves mainly in one direction through polarized lenses that eliminate glare.
