1.59 PC Progressive Photo Grey Blue Block Optical Lens Eyewear

The main performance is safety explosion-proof, you even use hammer hit it is not necessarily broken
The history of PC material lenses is relatively shorter, but thanks to the application of high quality raw materials, and ordinary resin lenses have essential differences!
At the same time, it also inherits the excellent characteristics of super impact resistance of raw materials, so this material is also commonly known as bulletproof glass after thickening

Spin coating change lens adopts spin change technology, completely subvert the previous base change technology. And base change ratio, it is uniform without background; Compared with the traditional film, it is better than immersion, the discoloration liquid and hard liquid in different processes, not only to ensure the adhesion of the discoloration liquid, fully maintain the discoloration tension, but also play a hard fixing effect, strengthen the hardness. With double layer rotary coating technology and hard protection, the process quality is greatly improved.

Progressive multifocal lenses are also called progressive lenses, which have multiple focal points on one lens as the name implies. If the lens is divided from the focus, it can be divided into single focus lens, double focus lens, multi focus lens.Progressive lens can realize the addition of near-use positive lens through the change of the lens center line of sight, so as to solve the problem of using different lens degrees for long distance objects, medium distance objects and close objects, and reduce or compensate the use of adjusting force. It enables the wearer to realize the vision of distant, medium and close continuous images without paying too much adjustment force.

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.
