Blue light can be seen everywhere in daily life, and what we call harmful blue light is actually high-energy blue light, During an interview with CCTV, the deputy director of the ophthalmology department at Fudan University Affiliated Hospital of Facial Sciences pointed out, "Especially blue light that exceeds a certain threshold and is too strong and high-energy, it can cause certain harm to our eyes. For example, blue light of 10 watts per square meter and 470 nanometers." A large amount of harmful blue light we come into contact with on weekdays comes from computer monitors, mobile phones, digital products, display screens, LEDs, and other light sources. ", Blue light within these wavelengths can seriously threaten our eye health.
The glasses processing factory knows that at present, anti blue light glasses are very popular in the sales market. I heard that anti blue light glasses can effectively reduce the damage to the eyes caused by blue light in the light source on computers, mobile phones, and other devices. Currently, the prices of anti blue light glasses on the market range from a few tens to several hundred or even several thousand yuan. So, are anti blue light glasses really anti blue light? How should we choose?
Blue light is also a key component of visible light, which has the characteristics of long wavelength and high kinetic energy. It can be further divided into green blue light and blue purple light according to wavelength categories. Blue light is not always harmful. At present, it is believed that green and blue light have beneficial components for the body, which have key effects in stimulating the closure of the pupils, regulating and maintaining the body's biological rhythm. High energy blue purple light is harmful to both eyes, as it can penetrate through the lens of the eye and directly reach the retina. Long term exposure of both eyes to blue and purple light can increase the production of lipofuscin in the eyes, resulting in phototoxic side effects and causing macular degeneration.
Therefore, Yancheng Glasses Processing Factory reminds consumers to be cautious when selecting anti blue light glasses, as not all glasses may be specialized anti blue light glasses. Some anti blue light lenses sold on certain platforms are non specialized lenses. Cheap anti blue light glasses not only fail to maintain human eyes, but long-term wearing can also cause fatigue and dizziness in the wearer's eyes.
The principle of good anti blue light lenses is to preserve favorable blue light and filter out harmful blue light.
