Product details
Blue light is a part of natural visible light, and sunlight and electronic screens will emit blue light. [1-2] Blue light is an important part of visible light. There is no separate white light in nature itself. Blue light, green light and red light show white light after mixing. Green light and red light have less energy, less eye stimulation, short blue light wave and high energy, which can directly penetrate the lens to the macular area of the eye, leading to macular disease.There are two kinds of blue light: beneficial and harmful [6]. The blue light with the wavelength between 415 and 455 [8] nm is short wave harmful blue light, which needs to be protected [9]. According to the complementary color principle of light, blue and yellow are complementary colors, so the glasses with blue light protection function are slightly yellow compared with ordinary lenses. The higher the barrier rate to harmful blue light, the darker the background color of the blue light proof glasses will beThe blue light proof glasses can effectively reduce the continuous damage of blue light to eyes. Through the comparative detection of portable spectral analyzer, the blue light intensity from the mobile phone screen is effectively suppressed after using the blue light proof glasses, reducing the damage of harmful blue light to eyes.Anti blue glasses mainly reflect harmful blue light by coating the lens surface, or absorb harmful blue light by adding anti blue light factor to the lens substrate, so as to achieve the barrier of harmful blue light and protect the eyes.The anti blue lens using film reflection technology reflects harmful blue light, so the lens surface will reflect blue light, while the anti blue lens using substrate absorption technology will not reflect blue light. As shown in Figure 4, the glasses reflecting blue light above are anti blue glasses.technology
