What is blue light & harmful blue light?

Blue lights are part of the natural visible light emitted by sunlight and electronic screens. Blue light is an important part of visible light. There is no single white light in nature. Blue light is mixed with green and red light to produce white light. Green and red light have less energy and are less irritating to the eyes. Blue light has a short wavelength and high energy, and can directly penetrate the lens to reach the macular area of the eye, causing macular degeneration. Among them, short-wave blue light with a wavelength of 400-450 nanometers is the most harmful to the retina.

 

Our Blue Cut Lenses' Advantages

Blue cut lenses feature a special coating that reflects harmful blue light and restricts it from passing through the lenses of your eyeglasses. Blue light is emitted from computer and mobile screens and long term exposure to this type of light increases the chances of retinal damage. Hence, wearing eyeglasses having blue cut lenses while working on digital devices is a must as it may help in reducing the risk of developing eye related problems.

Photochromic lenses, also known as "photosensitive lenses". According to the principle of light-color interconversion reversible reaction, the lens can quickly darken under light and ultraviolet irradiation, block strong light and absorb ultraviolet light, and absorb visible light neutrally; when it returns to the dark place, it can quickly restore the colorless and transparent state, ensuring the lens of transmittance. Therefore, photochromic lenses are suitable for both indoor and outdoor use to prevent damage to the eyes from sunlight, ultraviolet light and glare.
 

• INDOOR AND OUTDOOR SCENE CUT

Imported monomer makes  coating photochromic lens highly sensitive. It is colorless transparent indoor and changes according to UV strength outdoor. The stronger UV color is, the darker lens color is. Light transmittance will increase quickly when coming back indoorside from outdoor activities. Free scene shift provides customers with comfortable experience.
