People may be able to benefit from relief from migraines which ruin their daily lives thanks to the development of new spectacles in the US and UK.
A team led by Jie Huang and colleagues from Michigan State University and the University of Michigan, as well as experts from the University of Essex, have found that coloured glasses tuned to each migraine sufferer can normalise activity in the brain.
The result is a significant decrease in the pain and discomfort associated with migraines, the experts claim.
Mr Huang said the biomarker could prove useful, not only for the further evaluation of precision ophthalmic tints, but also for studying the effectiveness of drugs to prevent migraines.
In other research, specialists at Columbia University Medical Center have found that slowing down the build up of vitamin A in the eye could help to prevent vision loss caused by AMD.
