Jul 16, 2021
With the increase of the myopia population, which affects the health of the eyes, blue light has been paid more and more attention. How to prevent blue light has become a hot topic at the moment, and anti-blue light lenses have also emerged at the historic moment. So, what is blue light? What is the role of anti-blue lenses?
Light is everywhere in our lives. About 25-30 sunlight is blue light, and the light emitted by electronic devices also contains a higher proportion of blue light. So blue light is not mysterious.
Blue light is good for our health, but it is also bad for our health. Studies have shown that blue light between 400 and 520 nanometers (which has a great influence at 460 nanometers) is very important for regulating melatonin levels, controlling the biological clock and health. Long-term exposure to blue light below 460 nm (a serious impact at 440 nm) may cause optical damage to the retina and increase the risk of macular degeneration in the long run.
Therefore, what we need to do is to prevent harmful blue light from affecting our eyesight. In fact, it is not advisable for some products on the market to over-pursue blue light protection. Blocking the beneficial blue light will also affect the healthy development of our vision. The anti-blue lens is designed to block harmful blue light and reduce its adverse effects on vision.
Many anti-blue lenses on the market with high occlusion rate or obvious yellow color are used to filter blue light, which may cause color distortion of the human eye, decrease in clarity, and easily cause visual fatigue. Too yellow lenses will also affect people's judgment of light and color. The complete restraint of blue light will cause us to lose sight of blue objects under certain circumstances.
Anti-blue lens can give better eye care no matter indoors or outdoors. When used indoors, this kind of anti-blue lens can protect our eyes from the blue light caused by digital products and relieve the visual fatigue caused by using digital products. Outdoors, it can also effectively prevent ultraviolet rays.
