What are Polarized Sunglasses?
Polarized sunglasses use an anti-glare filter to create vertical openings for light to pass through. Not only do they make colours more distinguishable, but they also add clarity to your vision by reducing or eliminating glare from the sun.
How do polarized sunglasses work?
Polarized lenses have a special coating that’s aligned in horizontal rows across the lenses. These molecules absorb horizontally polarized light before it reaches your eyes but allow vertically polarized light to pass through. As direct sunlight is unpolarized, the polarization filter doesn’t completely block out the light – but don’t worry, polarized sunglasses contain other coatings that protect your eyes from direct sunlight.
