Sunglasses were first used in China in the 12th century or possibly earlier. The “lenses” of these glasses were flat panes of smoky quartz, which offered no corrective powers but did protect the eyes from glare.
Polarized lenses are another great choice and help to protect against the glare that is created when sun reflects off surfaces like water and highways. Polarized lenses are also very helpful when driving to reduce the glare on your car or the road. Sunglass Warehouse provides a variety of discount polarized sunglasses styles to fit your every mood.
Polarized sunglasses are perfect for reducing glare off of flat surfaces and from keeping your eyes from straining. Maui Jim polarized lenses and Oakley polarized lenses make up the majority of polarized sunglasses on Zappos. Polarization is also a good idea for anyone who uses the road (runners and cyclists) since it cuts down on glare from wet streets and sidewalks.
Polarizing sunglasses are especially popular with boaters, because the water reflects back a great deal of sun, which makes it hard to see and tires the eyes out. The glare can be distracting and dangerous, since it can make some objects (logs in the water, rocks and even other boats) hard to see.
Polarised sunglasses work by only allowing light through in a particular direction and blocking the reflective light that is thrown up from all directions and that creates the distracting reflections. Wearing polarised sunglasses will not only give you sharper vision but better depth perception as well. Polarized sunglasses are known to provide the absolute best protection from UV rays.
