ANU has the intriguing news that shining near infra-red light into damaged eyes encourages healing:
Australian researchers at The Vision Centre are working on a non-invasive method that involves shining near-infrared light (NIR) into damaged eyes to invoke a natural process which encourages the eye to heal itself.
“The use of NIR in healing eyes stressed by bright light has now been established, in animals,” said Dr Krisztina Valter from ANU and a Chief Investigator in the ARC Centre of Excellence for Vision Science.
“Now work has begun on the use of red light in human patients. Testing the effect of the light treatment is one aspect of this work, the other is to develop devices that are more accessible, more convenient and cheaper for patients to use.”
