Jiayu Product Knowledge: Anti Blue Light Glasses
1. About Blu-ray
Blue light is part of the natural visible light, and both sunlight and electronic screens emit blue light. It is an important part of visible light. Blue light has a short wave and high energy. It can directly penetrate the lens and reach the macular area of the eye, causing macular degeneration.
In the 2010 International Optical Association Annual Meeting, the world's top optical experts unanimously pointed out that short-wave blue light has extremely high energy and can penetrate the lens directly to the retina. Blue light irradiates the retina to produce free radicals, and these free radicals can cause the death of retinal pigment epithelial cells. The death of epithelial cells can lead to lack of nutrients in light-sensitive cells and cause vision damage, and these damages are irreversible.
2. Anti blue light glasses
Anti-blue glasses can effectively reduce the continuous damage of blue light to the eyes. Through the comparative test of portable spectrum analyzer, after using 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 by coating on the surface of the lens, or add anti-blue light factors through the lens substrate to absorb harmful blue light, thereby realizing 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.
3. Anti-blue light suitable for people
Anti-blue glasses are suitable for wearing when using digital display devices such as TVs, computers, mobile phones,etc. However, it is not recommended to wear anti-blue glasses for a long time in daily life, because anti-blue glasses filter some blue light, and the picture will be yellow when viewing objects.
