Prof Glen Jeffrey at University College London released the results of a small study looking at the effect of red lights (deep red 670nm in particular).
Prof Jeffrey’s work has been previously described in this blog. He and his team have clearly shown that deep red light is good for eyes.
Remember, though, only use LED lights.
Never ever use lasers on your eyes!
You can make your own eye light using LED strip and an old pair of glasses – here’s a link to a recent post showing a home-made eye light.
