A study by University College London, involving a small sample size of 24 people, has shown that staring at long wavelength light for three minutes every day can "significantly improve vision" in those aged 40 and above. The participants were given special LED torches to take home and were asked to gaze into its deep red 670nm light beam for three minutes a day for two weeks. They were then retested for colour vision as well as for vision at low light levels. "The technology is simple and very safe, using a deep red light of a specific wavelength, that is absorbed by mitochondria in the retina that supply energy for cellular function.
