A small LED torch that emits deep red light and costs just R260 (about US$15) to make could help improve declining eyesight, scientists have said.
A study by University College London, involving a small sample size of 24 people, has shown that staring at long wavelength light for three minutes every day can “significantly improve vision” in those aged 40 and above.
Scientists believe the discovery, published in the Journals of Gerontology, could pave the way for new eye therapies that are affordable and can be done by the patient at home.
