Polarized sunglasses are popular – and necessary – for those who do various outdoor activities ranging from fishing and boating to driving. A set of polarized lenses reduces the reflected glare from the water, snow, and other outdoor surfaces. For some, such as fisherman, wearing polarized sunglasses allows the user better viewing of the water and what’s underneath. For drivers, however, wearing polarized lenses is far more crucial: any glare distracting the driver or blocking his vision could result in an accident. Additionally, those with light-sensitive eyes are also recommended to wear polarized lenses, often with a photochromic feature added.

Polarized sunglasses have been available since 1936, when inventor Edwin H. Land created lenses with a Polaroid filter. In the present, such glasses are made from polarized plastic sheeting that selectively blocks out glare.

Light typically vibrates and radiates outward in multiple directions, but when it becomes aligned with one or more planes of direction, it is considered polarized. This can happen naturally and artificially. When polarized lenses are created, a chemical film is applied to transparent plastic or glass. This chemical compound is made of molecules that align naturally parallel to one another and creates a filter that absorbs any light matching their alignment.

Various types of sunglasses are designed with polarized lenses. Those designed for athletes, such as wraparound sunglasses, more commonly have polarized lenses, but others that are also fashionable are designed with this feature. If you need to have polarized sunglasses for long drives in daylight, for fishing, or for other outdoor activities, you’ll be able to find the look that fits you better through Vision in Style.

Polarized lenses and sunglasses should not be worn all the time, however. A pair of such glasses isn’t save for skiing – it can blur or block out dangerous surfaces – and for viewing LCD displays, which may be added to a vehicle.
