 1)Why we need the blue cut lens?

If you work on a computer, use a smartphone, watch TV, or simply go out in the sun, you are being exposed to high-energy visible (HEV) blue light. Too much blue light exposure can damage the eyes over time and even lead to vision loss. Today, more people are wearing blue-light-blocking lenses to protect their eyes from these potentially damaging rays.

2) What is the blue light?         

3) How the blue cut lenses protect your eye.

● Blue cut lenses can cut 100% UV rays, but don't mean can block 100% blue light, just cut part of the harmful light in blue light, and let the beneficial blue light allowed to pass.

● The function of Blue Cut lenses is to reduce the effects of blue light. Blue Cut Premium 35 absorbs 35% of the blue light – between the 420nm and 450nm wavelenght. Blue Cut Hi-tech 50 absorbs 50% of the blue light – between the 420nm and 450nm    wavelenght. Both absorb 100% of ultraviolet light, protecting the eye and making the use of electronic devices less inconvenient.
