Anti-blue Light Glasses -- a Boon for Electronics Enthusiasts

At present, with the rapid development of computer technology and network technology, all kinds of electronic products gradually spread in every aspect of our life. Online shopping, online courses, transportation office..."Cloud life" has become a normal part of our life.

Electronic products not only bring convenience to our life, but also make people spend more time staring at electronic screens, which will undoubtedly increase the risk of eye diseases. In order to make the picture quality of computers, mobile phones, ipads and other electronic products brighter and more beautiful, manufacturers often increase the blue light intensity of LED backlight. Studies have shown that blue light irradiation can cause damage to retinal cells, resulting in impaired vision or even complete loss of vision. Short-wave blue light is extremely powerful and can penetrate the lens all the way to the retina. Blue light exposure to the retina produces free radicals that cause the death of retinal pigment epithelium cells. The death of retinal pigment epithelium cells leads to the loss of nutrients to photosensitive cells and causes visual damage, which is irreversible. Therefore, the defense against blue light is very necessary.

Anti-blue light glasses, a kind of glasses designed for electronic enthusiasts, it uses anti-blue light lenses, which can effectively filter harmful blue light, isolate ultraviolet ray and radiation, reduce eye strain, and protect eyesight for a long time. It also designs different kinds of glasses for different groups of people, such as anti-Blue light computer glasses, anti-blue light gaming glasses, anti-blue light glasses for children.

The anti-blue light glasses mainly reflect the harmful blue light by coating the lens surface, or absorb the harmful blue light by adding the anti-blue light factor through the lens substrate, so as to achieve the barrier of the harmful blue light, and can be good for anti-eye strain . Professional anti-blue lenses usually have a bit of color, because while filtering out harmful blue light, the spectrum your eyes receive is certainly incomplete compared to the natural spectrum, resulting in color differences.

The anti-blue light glasses suits in the use of TV, computer and LED digital display equipment such as mobile phones, but in the daily life，we do not recommend wearing the anti-blue glasses for a long time, because the anti-blue glasses filter part of the blue light, vision images will be yellow. So, We suggest two pairs of glasses, one for daily use and one for anti-blue light when using LED digital products such as computers.

When buying anti-blue light glasses, we should pay attention to three indicators, namely blue light cut off rate, transmittance, color difference. Generally speaking, the barrier rate of blue light should be above 30%. Under normal circumstances, the interval of blue light barrier rate of 30%-50% can better block harmful blue light, while ensuring high light transmittance, color reduction and comfort. For people like heavy gamers and programmers, they can choose anti-blue light glasses with a barrier rate of 70%-80% or customize blue light lenses to protect their eyes from computer damage.

All in all, buying anti-blue light glasses is a good choice for electronics enthusiasts.
