Product Description

Spectacles Lens Index 1.67 Spin Photochromic Blue Block Lenses Spin coating Lens :  Spin coating Lens adopts spin change technology, which completely subverts the previous basic change technology. Compared with base transformation, it is uniform and has no background color; Compared with the traditional film changing method, it is superior to the soaking method. The color changing liquid and the hardening liquid are placed in different processes, which not only ensures the adhesion of the color changing liquid, fully maintains its color changing tension, but also exerts the hardening fixation effect and strengthens the hardness. With double-layer spin coating technology and hardening protection, the process quality is greatly improved.
Advantages: rapid and uniform color change. It is not limited by the material, and any ordinary aspheric surface, 1.56, 1.61, 1.67, 1.74, etc. can be processed into a film-changing lens. There are more varieties, and consumers have more choices.


Spectacles Lens Index 1.67 Spin Photochromic Blue Block Lenses What Is Blue Light?

Sunlight contains red, orange, yellow, green and blue light rays and many shades of each of these colors, depending on the energy and wavelength of the individual rays (also called electromagnetic radiation). Combined, this spectrum of colored light rays creates what we call "white light" or sunlight.

Without getting into complicated physics, there is an inverse relationship between the wavelength of light rays and the amount of energy they contain. Light rays that have relatively long wavelengths contain less energy, and those with short wavelengths have more energy.

Rays on the red end of the visible light spectrum have longer wavelengths and, therefore, less energy. Rays on the blue end of the spectrum have shorter wavelengths and more energy.
