BLUE CUT LENSES can effectively reduce the sustained damage of blue light to the eyes. Through comparative testing with a portable spectral analyzer, the intensity of blue light emitted by mobile phone screens is effectively suppressed after using anti-blue light glasses, reducing the harm of harmful blue light to the eyes.
BLUE CUT LENSES are suitable for wearing when using LED digital display devices such as televisions, computers, PAD, and mobile phones. no degree BLUE CUT LENSES are also popular among non myopic users, and are specifically designed for use in computer work, gradually becoming a fashion trend.
1. Substrate absorption: The BLUE CUT factor is added to the lenses substrate to absorb harmful blue light in daily life, achieving the protective purpose of blocking blue light.
2. Film reflection: The surface of the lenses is coated with a film to reflect harmful blue light, achieving the protective purpose of blocking blue light.
3. Substrate absorption+film reflection: This technology combines the advantages of the first two technologies, working together to provide dual protection. This technology is mainly applied to lenses BLUE CUT glasses.
Commercial LED lights, computers, mobile phones, and other electronic screens commonly encountered in daily life generate a large amount of blue light. Harmful blue light can easily cause retinal damage, poor mental state, and other problems, and the longer the time, the more obvious the harm. Therefore, it is necessary to prevent blue light!
◎ At present, the principles of blue cut lenses can be generally divided into the following three types
◎ The first type is film reflection - the surface of the lenses is coated with a film, which reflects harmful blue light through the film layer, achieving the protective purpose of blocking blue light.
◎ The second type is substrate absorption - adding anti blue light factors to the lenses substrate to absorb harmful blue light in daily life, achieving the protective purpose of blocking blue light.
◎ The third type is substrate absorption + Membrane reflection - This technology combines the advantages of the first two technologies and works together to provide dual protection.
Due to the principle of complementary colors, blue light+yellow light=white light, and when we want to remove blue light from white light, it is white blue=yellow. So the lenses have a yellowish background color!
