Dark red light improves vision: three minutes a day is enough for vigilance of the eyes

Dark red light improves vision

A shocking discovery was made by the ophthalmologists from the UK. They believe that deep red light is very good for the vision. If people look at the dark red light for only a few minutes a day, their vision improves significantly. For many years, the scientists have been trying to explain the process of natural visual impairment that millions of people all over the world are facing. Today, as the statistics say, on average about 12-15 million people aged 65 and over have vision problems due to aging of the retina in every European country.

In 50 years, that figure will increase to 20 million people. Professor Glen Jeffrey from the UCL Institute of Ophthalmology, noted that after 40 years, a person’s vision begins to deteriorate rapidly, and every year the problem grows. The scientists have conducted a series of studies, trying to restore vision and reverse its decline.


For that, short flashes of the long-wave light were used. Medicine believes that after 40 years, the retina begins to age and the pace of aging is determined by the mitochondria of the cells, their role is to generate energy and increase cell function. The density of mitochondria is considered the highest in the cells of the retinal photoreceptors. Moreover, they have high energy needs.

That is one of the reasons the retina ages faster than other organs. On that subject a lot of research have been done involving the laboratory animals, insects, and computer technology. The researchers accidentally drew attention to the improvement of the function of the retinal photoreceptors when the eyes were exposed to long-wave deep red light. Further research was already carried out with the involvement of the volunteers.

24 people were invited - 12 men and 12 women, aged from 28 to 72, without vision problems. The eyes of all participants were tested for sensitivity at the start of the study. It consisted in the ability to adapt in the dark, detecting weak light signals. These were blurry colored letters.


And then the participants were given flashlights so that at home they could observe the dark red glow every day for two weeks. After that, all participants were tested for sensitivity again. It turned out that the use of a flashlight did not affect young people, but the vision of people who were over 40 improved significantly. The results of the study proved that adult eyesight can be significantly improved using a simple short exposure to light waves.
