Three minutes of looking into the red light once a week can help our eyes as we age, a new study this week suggests. Researchers in the UK found that volunteers who were given a weekly session with a red light in the morning did well to test their color scheme. These findings are the most recent of which suggests that red light may be the cheapest and most readily available method due to the reduction of visible light years.
Last year, researchers from University College London printed the results of small human experiments involving red light therapy. Health volunteers were asked to look at the red “lamp” using their large eye for three minutes daily for two weeks. Subsequent tests revealed that people over 40 years of age were more likely to do well to test their visual acuity — the function of the optic nerve. Editor-in-chief Glen Jeffery told Gizmodo at the time that their findings provided evidence of their opinion.
Mitochondria are the part of the cell that produces most of its energy. But as we age, retinal mitochondria begin to degenerate faster than anywhere else, which is thought to contribute to the degeneration of our retina, especially our cones, and the gradual deterioration of our visual acuity. However, mitochondria absorb other types of light, including more red, and this increases battery, improving cell function – these work best in the retina because they have more mitochondria. That’s why we use this to see better, “Jeffrey explained.
Their new study wanted to test the effectiveness of their treatment. Instead of using the light daily, they added more light once a week. And he chose a dim light. The same length of the bright red light (670 nanometers) was used. The study involved 24 people between the ages of 34 and 70, all with a positive outlook. Many who received treatment were given in the morning. Some also received daytime as part of the post-test, and others did as a control group. They were then analyzed according to their color scheme, based on attempts to differentiate colors, until one week later.
Overall, those who received treatment in the morning showed a significant change of 17% on average, even after one week. Those who received treatment during the day did not change, possibly due to changes in the mitochondria that respond to light on the day the group’s previous research conducted. written. The results of the new study are printed in Science Reports.

“We demonstrate that one single exposure to long wave deep red light in the morning can significantly improve declining vision, which is a major health and wellbeing issue, affecting millions of people globally,” said Jeffrey in a notification from University College London.
These findings complement their past work, and may make the treatment more feasible, because the once-a-week look section is easier to adhere to than they do on a daily basis. But the team’s positive results are still based on small numbers of healthy volunteers. Major tests will be needed to confirm any benefits of red light treatment.
Even the authors admit that there are many questions left to be answered. Some of their volunteers, for example, were more interested in the service than others, even among the same seniors, meaning that there may be special features that predict how the service will work for everyone.
“In the near future, once a week a three-minute exposure to red light can be achieved while making coffee, or during a podcast listening session, and such simple additions could change eye care and vision around the world,” Jeffrey said in an interview with University College London.
Given its low cost (less than $ 15 per device, Jeffrey told Gizmodo) and simplicity, the team is happy with the potential for their support, if the research continues.
