Revitalizing Vision Through Red Light Therapy

The video discusses common eyesight issues as people age and introduces a UCL study that found exposure to red light at 670 nanometers for three minutes once a week in the morning can improve vision by 17%. The study highlights the importance of timing, as afternoon exposure showed no improvement. The video emphasizes aligning light exposure with circadian rhythms and suggests natural sunlight as an alternative. It concludes with additional tips for maintaining healthy eyesight.
