"Staring at a deep red light for three minutes a day can significantly improve declining eyesight, finds a new UCL-led study, the first of its kind in humans". Interesting, turns out our red flashlights are more useful than expected.

 

(the actual study is paywalled). EDIT (forgot to put the actual link to media articles), see the link that Mike G posted below or https://medicalxpres...t-deep-red.html.

Ah, sorry, I forgot to post the actual link to the summary, I had read it and was searching for the study or a pre-print but no luck.

Forget rose colored glasses. I'm getting a set of H-alpha ones.

I thought eating carrots improved your eyesight.

We were just discussing that here a day or two ago. Sure looks like marketing press-release-ish mumbo jumbo to me.   Tom

Agreed!

 

Even without reading the pay-walled article, N=24 is too small a number for any meaningful result. And no, it doesn't cost $12 to make, and $12 retail would be a healthy profit margin. This is an advertisement, not science.

I too think this would need to be peer reviewed.  I feel anyone staring into just any red light source for 3 minutes a day is a bit dangerous.  Sort of like injecting bleach but hopefully not as dangerous.  There would have to be careful examination of the light source, its wavelength, its intensity, and the distance from the eyes.  I could easily seeing someone mistakenly directing a red pet laser into their own eyes and causing injured retinas or worse.  The white light sources for helping people with depression disorder at least has a basis in fact and the white light source is supposed to be regulated.

Then you better not do any h-alpha solar observing with a P.S.T. or similar as they operated at 656.28 nm and this pilot study used 650nm.  I think the rest of us are just fine staring into our solar scopes for 3 minutes and more a day!  banjodance.gif

 

FWIW, this study was submitted to the The Journals of Gerontology in Feb 2020 and then published in Jun 2020, which is a monthly journal of The Gerontological Society of America that publishes within its covers the Journal of Gerontology: Biological Sciences and the Journal of Gerontology: Medical Sciences.  The publication requires peer review.
