The effects of harmful blue light on the eyes mainly include the following three aspects:
NO.1 Causing visual fatigue
Since the wavelength of blue light is short, the focal point will fall closer to the retina. In order to see clearly, the eyeball will be in a tense state for a long time, causing visual fatigue. In addition, the instability of the tear film caused by blue light can also cause visual fatigue. If your eyes are sore after using electronic screens for a long time, it is very likely that you have visual fatigue.
NO.2 Aggravating dry eyes
Studies have found that irradiation with a certain dose of blue light can damage the epithelial cells on the surface of the eye, causing or aggravating dry eyes. Therefore, long-term use of computers and mobile phones can cause dry eyes, eye pain, and photophobia and tears. This is one of the reasons.
NO.3 Causes vision loss
Harmful blue light has extremely high energy and can penetrate the lens directly to the retina, causing atrophy and death of retinal pigment epithelial cells. The death of light-sensitive cells will lead to decreased vision. The potential threat of harmful blue light to the eyes cannot be ignored. It is recommended that you: ① Follow the "20-20-20 eye protection rule": every 20 minutes of eye use, look at the scenery 20 feet (about 6 meters) away for 20 seconds to relax the ciliary muscles. ② Choose authoritatively certified anti-blue light glasses to effectively filter out the damage of harmful blue light to the eyes.
