Introduction of UV420 Blue Light Blocking Lenses
Blue light blocking lenses are specially designed eyewear lenses intended to filter and reduce harmful blue light radiation. Blue light is a type of high-energy shortwave light within the visible spectrum, with wavelengths ranging from 400 to 500 nanometers. It is widely found in natural light, LED lights, as well as on screens of digital devices such as computers and smartphones. Prolonged exposure to blue light can lead to eye fatigue, dryness, blurred vision, and even affect sleep quality. Therefore, the application of blue light blocking lenses aims to minimize the potential harm of blue light on the eyes, providing more comprehensive protection for eye health.
