Of course, there exists the whole field of photobiomodulation. Red light therapy (630/670/810/830/850/1060 nm red and NIR light) helps the eye in the morning (see Prof Glen Jeffery's work at UCL; the mitochondria are only sensitive to RLT during a certain window of the circadian rhythm, that coincides with early morning sunlight that is shifted towards the red/NIR), particularly when it comes to preventing and slowing age-related macular degeneration, but also improving colour perception, controlling blood glucose levels, improving athletic performance and recovery, mood and cognitive performance, and some other benefits. When I first got interested I thought I'd just get a small handheld LED device, but as I got deeper into it I decided to buy a large mains powered full body panel with 5 wavelengths. In particular the benefits to my sleep and skin have been fantastic, with the caveat that I live in northern Europe at a latitude of 53.3 degrees north. Perhaps those nearer the equator will feel more muted responses. That being said, improvements to vision are counterintuitively very difficult to actually judge without measuring, because the brain is constantly adjusting/hiding our defects.

Hi, do you happen to have to have some resources for someone interested in using red light therapy? Or even just a simple buying tip to get started. As someone with quite high myopia and a little bit of astigmatism thrown in, I'm at higher risk of myopic macular degeneration, so red light therapy might be extra useful!

I'm only seeing this now, sorry. First I'm not a doctor, so I can't give medical advice, certainly not if you believe you are already predisposed to something. I would say that there is no difference between the cheap and expensive devices, as long as they emit the correct wavelengths at the correct intensities. Since that's very low for targeting the eye (you are not trying to treat deeper joints/full body), you won't have to overspend. I think Prof Glen Jeffery mentioned a handheld red light in the 30 euro range for the morning treatment.

You can also look at (670/810 nm LED light strips to hang above your computer monitors and passively absorb some while starting at your monitor all day if you are getting an excess of blue light). I think that is another protocol though, but it might help.

I am sure though that it's more about consistency and treatment time (as in, you can't double the intensity to halve the treatment time). Furthermore, more is not better, it's more like an on/off switch after 2-3 minutes. You can do it every day, just like the solar spectrum is relatively higher in the required part of the spectrum at early morning sunrise every day.

But honestly, listen to Glen Jeffery, perhaps read /r/redlighttherapy
