When my mother's eye sight started declining she began sitting with closed eyes in direct early morning sunlight and claimed it helped her significantly, seems like science is finally catching up to folk medicine.

>With a paucity of affordable deep red-light eye-therapies available, Professor Jeffery has been working for no commercial gain with Planet Lighting UK, a small company in Wales and others, with the aim of producing 670nm infra-red eyewear at an affordable cost, in contrast to some other LED devices designed to improve vision available in the US for over $20,000.

Seems like the free therapy of sunlight is a better alternative to all the proposed commercial offerings, especially when considering patient compliance. Asking people to drink their morning coffee while outside is much more attainable than making them wear a headset with LEDs.
