what is polarized lenses

Polarized lenses are a type of treated lenses designed to reduce glare and eye strain, improving vision and eye safety outdoors. They are commonly used in sunglasses and work by filtering out some of the light that passes through the lens, blocking horizontal light waves that bounce off smooth surfaces such as water or a shiny car hood. This filtering creates vertical openings for light, allowing only light rays that approach the eyes vertically to fit through those openings. As a result, polarized lenses reduce glare and make images appear sharper and clearer, increasing visual clarity and comfort. However, polarized lenses can make images appear darker than usual, and they can hinder the ability to see LCD screens and LED lights, making them unsuitable for pilots.
