How To Find Out If Your Sunglasses Are Genuinely Polarized
Posted on 25 August 2016
What is so special about polarized lens? Polarized lens reduces glare and oncoming sunlight through the sunglasses. All of our wooden frame sunglasses have polarized lenses with UV400 protection in our sunglasses store. The UV400 blocks all wavelengths up to 400 nanometers including UVA and UVB light.
There are a couple of ways to test out if our sunglasses are polarized or not:
Take your sunglasses and put them up against an LCD screen. Turn your sunglasses at an angle until you see the sunglasses turning black.
