People who have harmed their eyesight through exposure to bright light may be able to recover through use of infra-red rays.
Dr Krisztina Valter of the ARC Centre of Excellence in Vision Science, which comprises research carried out by four universities in Australia, headed a team which has produced evidence to point to this conclusion.
Dr Valter said that eye cells which are exposed to too much bright light usually suffer stress from free radicals and die.
But exposing them to near-infra-red light seems to help them to recover.
The publication also gave an account of Professor Silvia Bisti at the University of L"Aquila, who has found that saffron may help protect and restore sight by assisting genes to improve the resilience of eye cells and acting as an antioxidant.
Most of the funding for the ARC Centre of Excellence is from the Australian Research Council.
The institution comprises the Universities of Western Australia, Sydney and Queensland, as well as the Australian National University.
