Guide to Sunglasses

Benefits of polarized sunglasses: Polarized sunglass lenses were first developed by Edwin Land in 1936. These special lenses have now been widely used to block out solar glare. Present now, polarized eyeglasses come in mainly two types: one is coated with a protective substance and the other has a filter enclosed within it. The former type is more common.

Those early sunglasses were equipped with crude frames and usually hand-held styles, which were quite different from sunglasses today.

Polarization and UV protection of sunglasses: Some people wonder that if inferior sunglasses with poor UV protection are more damaging than wearing no sunglasses. Although there are no confirming cases, it is to some extent reasonable that low-quality sunglasses are more harmful. Customers should always select quality sunglasses for best comfort and vision. Besides sunglasses, large hats are also helpful in offering sunlight protection outdoors.

Polarized sunglasses for outdoor activities: Polarized sunglasses were originally used to reduce reflected glare from the water in boating and fishing fields. With the development of polarized sunglasses, many others who participate in outdoor activities that require clear vision, such as skiers, bikers, golfers, joggers and so on are also interested in polarized sunglasses. Polarized sunglasses not only can reduce the glare from long, flat surfaces, but also are suitable for light-sensitive individuals working indoors, such as those continually exposed to light throw windows.
