Brush the circle of friends and short videos every day. How's your eyesight?
As we all know, as we grow older, our eyesight will get worse day by day. Especially after the age of 40, the sensitivity of retinal cells and color vision will gradually weaken. With the aging of the population and the wide application of smart phones, this problem will become more and more serious.
Previously, in a study published in gerontology, a research team from the Institute of Ophthalmology at University College London (UCL) found that staring at dark red light for three minutes a day could significantly improve declining vision. This study is the first in humans and provides us with a simple, safe and easy to operate treatment to try to slow the pace of vision decline.
Recently, a new study published by the team in scientific reports optimized this method, and the ideal therapeutic effect can be achieved by using less red light energy than in previous trials; Moreover, they also found the best treatment period.
For people around the age of 40, retinal cells begin to age. To some extent, the aging rate is caused by the decline of mitochondria that produce energy and enhance cell function. Photoreceptors in the retina are the places where mitochondria gather most intensively, and the demand for energy is very high. The retina ages faster than other organs. When ATP is reduced by 70%, it will lead to a significant decline in photoreceptor function.
Based on the previous research on mice, bumblebees and fruit flies, the team found that mitochondria have the characteristics that affect their absorption of specific light. When the eyes are exposed to 650-900nm (long wavelength) led dark red light, it can improve mitochondrial function, increase ATP production, reduce the production of reactive oxygen species, and reduce the rate of age-related cell death in the retina, The function of photoreceptor cells was significantly improv
