Red light and infrared light therapy may be useful for skin health and for offsetting age-related vision loss by helping mitochondria and photoreceptors.

“Um, I spoke to an opthalmologist yesterday. There's been a clinical trial using red light and infrared light uh, for what's called dry AMD, dry uh, macular degeneration um, to offset age related vision loss. And this looks promising. I mean it doesn't reverse age related vision loss completely but seems to help the mitochondria and the photo receptors. People are holding on to some vision that they would lose.”
