Polycarbonate was developed in the 1970s for aerospace applications and is currently used for the helmet visors of astronauts and for space shuttle windshields.Įyeglass lenses made of polycarbonate were introduced in the early 1980s in response to a demand for lightweight, impact-resistant lenses. AR coating eliminates distracting lens reflections that can interfere with vision, particularly when driving at night or in other low-light conditions when glare sources are present.

Polycarbonate and Trivex lenses both will provide clearer, more comfortable vision if anti-reflective (AR) coating is applied to the lenses. This combination of lightweight comfort, UV protection and impact resistance also makes these lenses an excellent choice for children's glasses and safety glasses. They also offer 100 percent protection from the sun's harmful UV light and are up to 10 times more impact-resistant than plastic or glass lenses. īoth polycarbonate and Trivex lenses are thinner and lighter than regular plastic lenses. When eye safety is a concern, polycarbonate or Trivex lenses usually are the best choice for your eyeglasses, sunglasses and sports eyewear.
