Cyxus Blue Light Blocking/Filter Computer Glasses Blue Blockers 8082


Why Cyxus uses Polycarbonate (PC) Lenses, while other similar products in the market are using the regular glass and plastic lenses (including other high-index lenses)?

The PC material used for eyeglass lens was developed in the 1970s by the aerospace industry for use in helmet visors worn by astronauts. Today, because of its lightweight and protective features, PC is used for a wide variety of products including space shuttle windshields, luggage, "bulletproof glass," helmet visors of astronauts and police, swimming goggles and diving masks, Eyeglass lenses made of polycarbonate were introduced in the early 1980s in response to a demand for lightweight, impact-resistant lenses.

Since then, PC lenses set the standard in eyewear safety, These lenses are a smart choice for athletes, those who work in hazardous job environments, and especially for children. Kids have a greater tendency to drop their glasses and play a bit rough, so ideally all children’s frames should have polycarbonate lenses. Polycarbonate lenses are also a good choice for people who wear rimless eyeglass frames where the lenses are attached to the frame components with drill mountings because they are less likely to fracture than regular plastic or glass lenses.

Polycarbonate lenses are up to 10 times more impact-resistant than glass or regular plastic lenses and they provide 100% protection from the sun's harmful UVA & UVB rays. And they exceed the FDA's impact resistance requirements by more than 40 times.

  • PC lenses are highly resistant to impact, won’t shatter, and are 10 times stronger than glass or standard plastic, making them ideal for children, safety lenses, rimless eyeglass, and physical activity.
  • Lightweight and thinner than glass lenses, polycarbonate is more comfortable to wear for long periods of time.
  • Polycarbonate inherently blocks 100 percent UV rays without needing a special coating.
  • Due to the lightweight and flexibility of polycarbonate, these lenses are easier to remove and install than glass lenses and are available in more styles of computer glass/sunglasses that cannot accommodate heavy glass lenses.

For your eyewear, choose a sturdy frame and lightweight polycarbonate lenses. Even if you do not participate in organized sports, choosing impact-resistant eyeglass lenses and frames is an important step to protect your eyes throughout the day for a lifetime of good vision.
