Описание
The nylon lenses is made of nylon material, which is a transparent polyamide, which breaks the regularity of molecules by introducing side groups into the molecular chain and inhibits the formation of crystals, thereby obtaining transparent polyamide. Nylon lenses are widely used in eyewear of various materials because of their good light transmittance and strong toughness, including acetate glasses, metal glasses and titanium glasses, especially half-frame, rimless and glasses with less regular lens shapes.
The main features of nylon lenses are good toughness, strong impact performance And good transparency (slightly worse than CR 39). The main disadvantage is that the wear resistance is worse than CR 39, and the production cost is higher than CR39. It is one of the most commonly used sunglasses lenses.
