Polarized Photochromic Sports Sunglasses
The revolutionary new sunglasses with built-in Polarized Photochromic Sports Sunglasses. These unique lenses respond to changing lighting conditions almost instantly! Lenses automatically darken on a bright light and lighten on low light. This effect is achieved by the photochromic lenses in our glasses.
HOW DOES IT WORK
Photochromic lenses achieve their photochromic properties through the embedding of microcrystalline silver halides (silver chloride) in the lenses. These lenses darken when exposed to ultraviolet light of the intensity present in sunlight, but not in artificial light. In the presence of UV-A light, electrons from the glass combine with the colorless silver cations to form elemental silver. And because elemental silver is visible, the lenses darken.
The Polarized Photochromic Sports Sunglasses
Our sunglasses block all three ranges of ultraviolet radiation: UVA, UVB and UVC and protect the human eye 100% from harmful effects of the sun rays. This is achieved by a multi-layer lens design for optimal eye protection.
The Polarized Glasses are not only superior in lens technology but also surpasses all competition when it comes to building quality and durability. Our frames are made of Aluminum and Magnesium which are known for their extreme strength while being lightweight.
◆ Photochromic: The lenses can change their color automatically under different weather conditions. The stronger the outdoor sunlight is, the darker the sunglasses will be.
◆ 100% UV Block: The lenses can also block 100% harmful rays to better protect your eyes.
◆ Polarized: Sunglasses are specialized eye-wear designed to reduce glare from surfaces such as water, snow, and glass. Glare distorts the true color of objects and makes them harder to distinguish.
◆ High Definition: Guarantees a clear vision at nights, sunny days, and cloudy days.
◆ Indestructible Frame: Ultralight magnesium-aluminum frame, extreme durability while remaining stylish.
◆ Comfortable to wear: Adjustable arms and silicone nose pads to fit all faces. Environmentally friendly material prevents allergy and give you a comfortable wearing experience.
