Books – Sayed Metwally:
Did you know that your eyes are aging faster than you know them? Over the age of forty, your eyes do not work as usual, specifically the retina, the area at the back of the eye, which detects black and white images and colors.
Professor Glenn Jeffrey of the UCL Institute of Ophthalmology is looking for a way to avoid this deterioration, and has decided to try to restart the “aged” retina with short bursts of long-wave red light, according to the British newspaper “Mirror”.
Glenn found that looking at the deep red light for three minutes a day can rejuvenate the retina and improve eyesight. These results could warn of home eye remedies to combat vision deterioration.
“Your retinal sensitivity and color vision diminish gradually, as a person reaches old age,” says Professor Jeffrey.
Around the age of 40, retinal cells begin to age, and this aging increases in frequency when the retina cannot produce enough energy to function as usual.
Researchers previously found that red light improves vision in mice, bees, and flies. Retinal photoreceptors come in two types – cones, which detect color vision and rods, which give vision in dim light.
In this study, 24 subjects (12 males and 12 females) aged 28 to 72 years were tested for retinal receptor sensitivity.
All participants were then asked to look at a deep red beam of light from an LED torch for three minutes daily for two weeks, and were then retested for penis and cone sensitivity.
Red light did not affect people under the age of 40, but there have been major improvements in people ages 40 and over.
In these people, the ability to detect colors improved by up to one-fifth, there were more significant improvements in the blue part of the color spectrum and the ability to see in low light also improved significantly.
Professor Jeffrey said: “Our study shows that it is possible to significantly improve vision in elderly individuals, by using simple, brief exposures to wavelengths of light that recharge the energy system that has been reduced in the retinal cells. This technology is simple and safe.”
