Deep Red Light Therapy Corrects Vision

On average, the researchers found that color contrast vision improved 17% after a single three minute morning session of exposure, and it lasted for at least a week.. However, when the study was repeated in the afternoon, no improvement was observed. They believe this is related to the shifting work patterns of mitochondria. The promising results of the study give hope for low-cost, non-invasive at-home treatments for naturally declining eyesight.
