The truth about red light therapy for your eyes:
- Glenn Jeffries' lab: red or near-infrared light to the eye at about 2 feet for a couple of minutes a few times a week early in the day
- Two published studies show offset of vision loss from macular degeneration in people over 40
- Mechanism: better-functioning mitochondria in photoreceptors and fewer reactive oxygen species
- Dose brightness wavelength and timing are still open questions
- Any light that is too bright can damage your eye - it should never be uncomfortably bright
