Staring at a deep red light for three minutes a day can significantly improve declining eyesight, according to a new study led by University College London, News Medical reports. The study is the first of its kind in humans.
Scientists believe the discovery, published in the Journals of Gerontology, could lead to new affordable home-based eye therapies, helping the millions of people globally with naturally declining vision.
The study's lead author, Professor Glen Jeffery, said: "As you age, your visual system declines significantly, particularly once over 40.
"Your retinal sensitivity and your color vision are both gradually undermined, and with an aging population, this is an increasingly important issue."To try to stem or reverse this decline, we sought to reboot the retina's ageing cells with short bursts of long-wave light."
Researchers found the light had no impact in younger people, but in those around 40 years and over, there were significant improvements.
