In order to make the image quality of various LED light-emitting display devices such as TVs, computers, PADs, and mobile phones brighter and more beautiful, manufacturers often increase the blue light intensity of the LED backlight. With the popularity of these electronic products and permeate all aspects of life, Everyone’s exposure to blue light has increased dramatically. For ordinary people, blocking blue light for a long time is the most effective way to reduce damage, and the use of anti-blue glasses can effectively solve this.
Anti-blue glasses can effectively reduce the continuous damage of blue light to the eyes. Through the comparative test of the portable spectrum analyzer, after using the anti-blue glasses, the intensity of blue light emitted by the mobile phone screen is effectively suppressed, reducing the harmful blue light to the eyes.
Anti-blue glasses mainly reflect harmful blue light through the surface coating of the lens, or add anti-blue light factors through the lens substrate to absorb harmful blue light, thereby achieving the blocking of harmful blue light and protecting the eyes.
Any anti-blue lens that uses film reflection technology, because it reflects harmful blue light, the surface of the lens will reflect blue light, and the anti-blue lens with substrate absorption technology will not reflect blue light.
