In Just 3 Minutes a Week, You Can Significantly Improve Your Declining Eyesight.
According to a groundbreaking new study by UCL researchers, just three minutes of exposure to deep red light once a week, delivered in the morning, can considerably repair failing eyesight.
The discovery, which was published in Scientific Reports, builds on the team’s previous research, which found that daily three-minute exposure to longwave deep red light’switched on’ energy-producing mitochondria cells in the human retina, helping to boost naturally deteriorating vision.
The goal of this current study was to see what effect a single three-minute exposure would have while using far lower energy levels than in earlier experiments. Furthermore, the scientists examined morning and afternoon exposure, based on earlier UCL study in flies that indicated mitochondria display’shifting demands’ depending on the time of day.
In summary, researchers discovered that three minutes of 670 nanometers (long wavelength) deep red light in the morning improved participants’ color contrast vision by 17 percent on average, and that the effects of this single exposure lasted for at least a week. When the same test was done in the afternoon, however, there was no improvement.
The discoveries, according to scientists, signify a milestone for eye health and should lead to affordable home-based eye remedies, benefiting the millions of individuals worldwide who suffer from naturally deteriorating vision.
“We demonstrate that one single morning exposure to long wave deep red light can considerably restore decreasing eyesight, which is a major health and wellness issue affecting millions of individuals globally,” stated lead author Professor Glen Jeffery (UCL Institute of Ophthalmology).
“This modest intervention, if implemented at a population level, would have a considerable influence on people’s quality of life as they age, and would almost certainly result in lower social costs related with visual disorders.”
Cells in the retina of the eye begin to age at the age of 40, and the rate of this aging is accelerated in part by the loss of the cell’s mitochondria, which produce energy (ATP) and boost cell activity.
Mitochondrial density is highest in photoreceptor cells of the retina, which have high energy demands. As a result, the retina ages more quickly than other organs, with a 70% loss in ATP over the course of a lifetime, resulting in a considerable decline in photoreceptor function as they lack the energy to execute their typical function.
