1. Polycarbonate Lens
Polycarbonate, also known as poly, was invented by the aerospace industry for gear used on the Apollo space shuttle (helmet visors etc.). It is an impact resistant material that is highly recommended for rimless, safety glasses and sports eyewear. Poly is known for its resistance to chipping or shattering and is 40 times more resistant than FDA requirements. However, once polycarbonate is severely scratched it may loose its impact resistance qualities.
Poly is a flexible material that needs a hard coat to protect it from easily scratching, but also has a natural UV protective nature.
2. Blue Cut Lens
♦ What is blue light?
Blue light is part of the visible light spectrum, just next to violet. Studies show that the blue-violet light emitted by many digital screens is the most harmful to eyes, according to the Paris Vision Institute. Younger people could start to experience age-related macular degeneration, a leading cause of vision loss for people over 50, due to excess blue light exposure.
♦ How to protect your eyes?
Digital screen protection glasses from EyeBuyDirect are specially designed to filter out a portion of harmful blue-violet light. The premium features of Eyezen lenses, such as Eyezen Focus, make screen time more comfortable and help eliminate symptoms of digital eyestrain.
