New study shows red light exposure in mornings could help eyesight.

Amazing science. Sounds skeptical, but there is a scientific link at the bottom.

Actually, this is a somewhat common path to successful science. One observes an interestingly pattern in, for example, how organisms process/respond to light, formulate a hypothesis as to mechanics and test in a new target population.

To quote from the source:

"In studying the effects of deep red light in humans, researchers built on their previous findings in mice, bumblebees and fruit flies, which all found significant improvements in the function of the retina’s photoreceptors when their eyes were exposed to 670 nanometre (long wavelength) deep red light."

Not hard to replicate at home...

Hmmm. You mean the nutcases who recommend staring at the sun every sunrise and sunset weren't completely out to lunch?

Just out of curiosity what is the wavelength for a typical red light bulb bought at a hardware store? Does anyone have any tools to measure wavelength of light at home?

This is a good point... Sunlight after all, is like 53% IR, 3% UV, rest visible light. So we do see IR every morning anyways.

I spent 30$ on some components ...300/ea @ 650/660nm LED and a few 500v 1MΩ resistors to round out the purchase and make shipping just under half the product costs. When they get in, you can bet I'll plug a few in some dollar store LED flashlights. I see no lost $ in trying to prevent eyesight loss for so cheaply even if it is a hoax.

Just turned 43, still need them goo filled orbs functional as long as possible
