Blue light is part of the natural visible light that is 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 light and red light to produce white light. Green light and red light have less energy and less stimulation to the eyes, while blue light wave is short and high energy, which can directly penetrate the lens to the macular area of the eye, resulting in macular lesions.
Blue light can be beneficial or harmful. The blue light with wavelength between 415 and 455 nanometers is harmful blue light of short wave, which needs to be protected. According to the complementary color principle of light, blue and yellow are complementary colors, so the glasses with the protection function of blue light will be slightly yellow compared with ordinary lenses. The higher the barrier rate of harmful blue light, the darker the background color of the anti-blue light glasses will be.
Production Introduction
Because of the short wavelength of blue light, the focus is not at the center of the retina, but farther forward. In order to see clearly, the eyeball is in a state of tension for a long time, causing visual fatigue. Long-term visual fatigue may lead to the deepening of myopia, diplopia, easy serial reading, inability to concentrate and other symptoms, affecting people's learning and work efficiency. Blue light suppresses the production of melatonin, an important hormone that affects sleep and is known to promote sleep and regulate jet lag. This could also explain why using a phone or tablet before bed can lead to poor sleep quality and even difficulty falling asleep. TV, computer, PAD, and mobile phones and other kinds of LED display device, the manufacturer to make its effect is more bright beautiful, quality tends to improve LED back light blue light intensity, along with the popularity of these electronic products and penetrated into every aspect of life, each person increases sharply, exposure to blue light for the ordinary people, Blocking blue light for a long time is the most effective way to reduce damage, and the use of blue light blocking glasses can effectively solve this problem.
