Just three minutes of exposure to deep red light once a week, when delivered in the morning, can significantly improve declining eyesight. It could lead to affordable home-based eye therapies, helping the millions of people globally with naturally declining vision.

Retina surgeon here. The issue is that the problem this tries to address may not be an important issue. The main reason that people “naturally lose vision” with age is cataracts (not retinal sensitivity), but modern cataract surgery has essentially cured the disease. It is essentially expected for patients older than 80 to have 20/20 vision in both eyes. Ive had 100 year old patients who are 20/20 thanks to cataract surgery. Patients who get cataracts usually tell me they feel they see better than when they were a young adult. There is a natural slow decline in contrast sensitivity, which this purports to treat, which has some importance but most patients dont actually complain of this unless its significantly worsened (like in macular degeneration). In other words, this sort of feels like a hammer trying to find a nail. Its neat if it works in larger trials, but unless theres something ground breaking that Im not seeing here I wouldnt prescribe this to the average healthy patient (in spite of age). Id hope however that maybe this could be helpful in diseases like macular degeneration where we have very few effective treatments, and may have some mitochondrial roots.


You have to look pretty deep into this paper to find that only 10 people were studied here. Don’t get too excited, the majority of such small clinical studies are never replicated…


Ok I thought I was INSANE but when I’ve been on the computer all day, going outside and staring at the sun with my eyelids closed feels really good for about 30 seconds….anyone else do this?


So… wake up, get a cup of coffee, and visit the red light district?


So where did this come from? I mean is this a remnant of people stumbling out of their caves in the morning and watching the sun rise??
