Vision loss may improve when looking at a red light

A recent study by scientists at University College London (UCL) has found that staring deep red light for three minutes a day can significantly improve vision decline.

Experts say the discovery could signal the start of new affordable eye therapies for everyone, Eurekalert reported.

The experts’ idea is that an individual who has vision problems could practice this mechanism for three minutes a day and could notice changes in a few weeks.

In the words of lead research author Glen Jeffery, “As we age, the visual system begins to slow significantly, especially when a person is past the age of 40.”

“The sensitivity of the retina and the perception of color gradually begin to weaken, and as the population continues to age, it is an issue that is becoming annoying for many,” he added.

Following this, experts argue that longwave red light could halt or reverse this advance as it would help restart aging cells within the eye.

Over the years, most people begin to lose their vision, caused mainly by the mitochondria of the cells inside the eye, whose role is to produce cellular energy (ATP) and thereby increase the function of sight.

This activity is greatly reduced when the person begins to age and the mitochondrial density begins to demand more energy inside the retina, making it age faster.

However, thanks to the experiment developed by the experts in mice, bumblebees and flies exposed to high-density deep red light (670 nanometers), significant improvements to this process were achieved.

In the words of the scientists “all mitochondria have specific characteristics of light absorbency, which directly influences their performance. When they absorb long waves between 650 and 1,000 nanometers, their performance inside them is considerably improved. ”

Following this previous investigation, experts cited a total of 24 people, including 12 men and 12 women between the ages of 28 and 72.

The study analyzed the quality of their vision and also analyzed the behavior when analyzing various light signals, in addition to being able to detect colors.

Subsequently, all participants were given a small red LED light to look at it for three minutes a day for just two weeks, and then analyze the results.

After complying with the process, the experts reported that young people (28 to 40) did not show a significant improvement in their condition, but older people did notice a change in vision, which the participants described as a “surprising improvement”. .

Given this, the experts emphasized that “our study showed that it is possible to improve vision that has decreased in older individuals, by brief exposure to the wavelength of light.”

“The technology is simple and safe and only a low-cost device is needed in the market, making it accessible to all kinds of people,” the team said.
