People with photosensitive epilepsy could benefit from a prototype pair of glasses with lenses that block out wavelengths that are known to cause seizures in some people.

In a study published in Cell Reports Physical Science, researchers from the University of Glasgow and University of Birmingham have developed a prototype of a liquid crystal lens that they believe could help photosensitive epilepsy sufferers.

The lenses are controlled by very small changes in temperature that can be built into the lens, and when activated can block more than 98% of light in the 660–720nm wavelength range, known to affect the greatest number of people suffering from photosensitive epilepsy.

Zubair Ahmed, Professor of Neuroscience at the University of Birmingham and co-author of the study said, "This is a hugely exciting project that felt like a science fiction project when we first started the work four years ago. This paper demonstrates the potential for the use of liquid crystal lenses that can be modulated to cut out specific wavelengths of light."
