At present, the anti-blue light lenses on the eyeglass mart mainly consist of transparent lenses coated with a blue light filtering film and lenses with a light yellow background color.
Should I choose anti-blue light lenses? Blue light has a wavelength of 400-500nm, with the shortest wavelength but the strongest penetration. Among the various LED products we use, there are only three types of light: red, green, and blue, with blue light being the main one. Therefore, continuous gaze at electronic screens can have a certain impact on the eyes.
Blue light includes blue-green light that is beneficial to the human body, such as sunlight, which can adjust the circadian rhythm, affect the biological clock, and improve visual quality.
Blue light with a wavelength of around 415nm-445nm is called blue-violet light, which is a harmful blue light band to the human body. It can cause visual fatigue, inhibit the secretion of melatonin, and damage the retina.
In terms of effect, light yellow colored lenses are better than transparent lenses, but their visual effect and aesthetics are not as good as transparent lenses.
Ordinary people using lamps that have passed quality inspection and are guaranteed to be of high quality need not worry about excessive blue light damaging the retina. However, people with special illnesses that require medical advice, such as after cataract surgery, should choose to wear anti-blue light glasses.
For people who use electronic products for a long time and with high intensity, the reasonable use of anti-blue light discountglasses can reduce the damage of blue light to the eyes and protect them.
Compared to anti-blue light glasses, it is more important to pay attention to eye use. In other words, using your phone in a way that is better for your eyes is appropriate.
