Red Light Could Improve Your Eyesight

Looking into a deep red light in the morning could help save fading eyesight.

British researchers found that a daily three-minute exposure to long-wave deep red light, in the morning, switched on energy-producing cells in the retina, giving a boost to naturally declining vision.

On average, those participating in the small study saw a 17 percent improvement in color vision, which lasted a week, and some of the older participants had a 20 percent improvement that lasted a week.

The same effect was not seen when eyes were exposed to the red light in the afternoon. The scientists note the technology is “simple and very safe,” and could be made available at an affordable cost to the general public.
