Wearing blue light glasses correctly can filter harmful light to a certain extent and reduce the possibility of eye vision deterioration. However, the use of blue light glasses by minors can easily affect the normal development of color vision. Human retinal photoreceptor cells are sensitive to blue light. Glasses that filter blue light can appropriately reduce the possibility of macular lesions caused by eye cells. blue light glasses will block blue light. After wearing glasses, there will be a certain deviation in the brightness and accuracy of the color light, which may affect the visual development of children under 12 years old.
In a medical experiment conducted by the University of Houston in the United States, subjects were recruited to participate in the study of wearing yellow anti-blue glasses. After wearing anti-blue glasses for about 4 hours (from about sunset to bedtime), lasting for 2 weeks, their melatonin level was significantly increased by 58% during the night through saliva test. Some subjects had poor sleep quality, which improved after the experimental period; Improving melatonin at night can improve the quality of sleep, further prevent myopia and prevent the increase of myopia.
This experimental data shows that the use of anti-blue light glasses is very important. It can filter most of the electronic blue light at night, reduce the stimulation of non-imaging visual cells (ipRGC), and help improve people's sleep quality. In addition, the subjects fall asleep early, and objectively add 24 minutes of sleep time every night, which has a positive impact on the adjustment of human circadian rhythm.
