All parents want their children to be healthy and happy, and the same applies to anyone fitting a child for prescription eyeglasses. To ensure health, most experts agree that polycarbonate is the best choice for the lens material because it has outstanding impact resistance, excellent durability, and is light weight. Parents will want their children to wear eyeglasses with these “shatterproof” lenses since they protect young eyes from the impact of airborne objects and falls. To keep children happy, it is important that eyeglasses fit well so that youngsters are not bothered by wearing or constantly adjusting them. As such, eyeglasses with adjustable nose pads, cable temples that wrap around the ears, and spring hinges that resist breakage are recommended. Polycarbonate lenses are manufactured with a scratch coating and are UV resistant.
