Long-wave light for 3 minutes a day can improve vision with age, say doctors at University College London.
The retinas age faster than any other organ in the body, but now a way has been found to stop this and even reverse it. All you need is exposure to long-wave red light for only three minutes a day.
In the study, 24 people – 12 men and 12 women – with healthy eyes used LED flashlights emitting deep red long-wavelength light waves to irradiate their eyes for three minutes a day for two weeks.
After that, the cones and rods that make up the human retina were tested for sensitivity. Participants older than 40 years after revealed “significant improvement” in the retinal visual cells, experts say.
