What is the best lens material and what are the main differences? There are three basic lens materials: plastic, polycarbonate, andCheap Oakley Sunglasses. Plastic lenses are lightweight, tint easily, and are more shatter resistant than glass lenses. Plastic lenses do tend to be thicker than polycarbonate lenses, and usually require special scratch-resistant and UV coatings.

Polycarbonate lenses are very lightweight, block 100% of UV rays naturally, and are 10 times more impact resistant than regular plastic or Oakley Designer Sunglasses lenses. This makes polycarbonate lenses one of the most popular choices. Glass lenses are the most expensive option because they offer superior optical clarity and exceptional scratch resistance, however Oakley Prescription Glasses lenses are a bit heavier than plastic or polycarbonate lenses.

What types of Discount Oakley Sunglasses lens coatings are available? Coatings can include mirror, anti-reflective, scratch-resistant, and UV. A mirror coating is applied to the front surface of the lens to reflect light, thereby reducing the amount of light actually passing through the lens. Mirror coatings are not transparent, which many prefer. http://www.cheapoakleyonlinestore.com
