Watersports Polarized Lenses
It's all about glare, not about UV protection
On flat roads or smooth bodies of water, light is generally reflected in a horizontal direction, instead of its usual scattered fashion. This horizontal polarisation creates glare -- and this is what polarised lenses target. POLARISED lenses filter out scattered, glary light off reflected surfaces and makes it a more comfortable light to view.
Traditionally worn by fishermen and boaters to extend their gaze further down the boat or deeper into the water, now many others who spend time on water have discovered the benefits of polarized lenses.
Polarized sunglasses can be helpful for driving too, particularly on wet roads, because they reduce glare-causing reflections from flat surfaces, such as the hood of the car or the road's surface.
On cheep polarized sunglasses, lenses are quite thin, they are not shatter resistant and the polarisation is usually just a layer on the front that can be scratched off, or are made of two lenses glued together with a polarizing film in-between. These lenses contain adhesives and other imperfections that reduce clarity and increase eye strains. They can also warp a little by bending the flat polarized sheet, which is not ideal in terms of optical comfort.This could explain the headaches and dizziness that you feel coming on and are particularly common with wraparound sunnies
Alpinamente’s lenses are created using a state-of-the-art injection process. This process allows us to embed the polarization in the material itself without adhesives. The result is an optically correct Polarized lens with extremely high clarity.
