• The Effect Of Sunglass Lenses

Sunglasses can provent uncomfortable glare, while protecting your eyes from UV rays.

All thanks to metal powder filtration devices that "choose" when it comes in. Colored spectacles selectively absorb part of the wavelength band that makes up the sun's rays because of the use of very fine metal powders (iron, copper, nickel, etc.). In fact, when light shines on the lens, light is diminished based on the so-called "destructive interference" process. That is, when light of certain wavelengths (here UVa, UVB, and sometimes IR) travels through the lens, they will cancel each other out inside the lens, ie toward the eye.

It is not by chance that the formation of light waves overlaps with each other: the wave crests of one wave, together with the wave troughs of the wave near it, result in mutual cancellation.

• The Usage of Sunglass Lenses

1. Casual sunglasses
Best for everyday use and basic recreational activities, casual sunglasses do an excellent job of shading your eyes from the sun while you drive to work and walk through town. Casual sunglasses are typically not designed to handle the intensity of action sports.

2. Sport sunglasses Designed for activities such as running, hiking and biking, sport sunglasses offer light weight and an excellent fit for fast-paced adventures. High-end frame and lens materials are more impact-resistant and flexible than casual sunglasses. Sport sunglasses also typically feature grippy nose pads and temple ends, a feature that helps keep the frames in place even when you're sweating. Some sport sunglasses include interchangeable lenses so you can make adjustments for different light conditions.

3. Glacier glasses
Glacier glasses are special sunglasses designed specifically to protect your eyes from the intense light at high altitudes and sunlight reflecting off snow. They often feature wrap-around extensions to block light from entering at the sides.
