Staring at deep red light improved eyesight in aged 40 and up

28-Jun-2020

Key points from article :

Looking into deep red light can significantly improve declining eyesight.

In 50 years, UK will have 20 million people aged over 65, all will have visual decline.

"Your retinal sensitivity and your colour vision are both gradually undermined."

"We sought to reboot the retina's ageing cells with short bursts of longwave light."

In humans around 40 years-old, cells in the eye's retina begin to age.

The retina ages faster than other organs, with a 70% ATP reduction over life.

Animal models show vision improvement when exposed to 670 nanometre deep red light.

24 people (12 male, 12 female), aged 28-72, who had no ocular disease, were recruited.

All given a small LED torch to look into deep red 670nm light for 3 minutes/day in 2 weeks.

No impact seen in younger people, but significant ones to those 40 and up.

"Our devices cost about £12 to make, so the technology is highly accessible to members of the public."

Research from University College London, published in The Journals of Gerontology.

Animal and human models show significant results for a £12 device
