Introduction

Nowadays, everybody encounters blue light in daily activities. Fluorescent lighting, electronic screens (phones, computers, TVs, etc.), and the sun emit damaging high-energy blue light.

What are the dangers of blue light?

Blue light causes the gradual oxidation and deterioration of the retina over your lifetime. Leaving our eyes exposed and susceptible to developing macular degeneration. Bluecut Lenses provide a protective shield to such harmful dangers and visual troubles by bolcking the transmission of blue light of 420~450nm wavelength.

The difference between anti-blue lens and ordinary lens: anti-blue lens and ordinary lens are yellow-green film, but ordinary lens has a yellow feeling under the reflection of light; The anti-blue lens is light blue in the light and can reflect the blue light.

Blue light is divided into beneficial and harmful. Blue light with a wavelength between 415 and 455 nm is short-wave harmful blue light, which needs to be protected. According to the principle of complementary color of light, blue and yellow are complementary colors, so glasses with blue light protection function will be slightly yellow compared with ordinary lenses. The higher the blocking rate of harmful blue light, the darker the background color of anti-blue light glasses.
