Описание
Benefits:
- lightness
- The specific weight of optical plastic is half that of glass, so your glasses with plastic lenses will be much lighter.
- injury safety
- The risk of injury to the eyes from shattered lenses is much less if those lenses are — plastic. And because the plastic is more resistant to splitting, and because the fragments are not so traumatic.
- cosmetic colors
- Plastic, unlike glass, gives lens manufacturers and opticians complete freedom to color lenses with complex cosmetic shade combinations, with multiple color transitions.
Gradient lenses have a color that usually fades from a darker shade to a lighter shade. The advantage of such a lens lies in its ability to reduce the intensity of sunlight falling from above. At the same time, bright objects located at the level of human growth and on the ground remain visible. Gradient lenses can be worn indoors and at dusk without any problems. Although the lenses provide 100% UV protection, they do not protect against very bright light – if you are going to spend a lot of time in the blinding sun, it is better to choose a darker lens. But lenses with the "gradient" effect - a great accessory for any season.
