Innovative Lenses Designed to Prevent Seizure-Inducing Light

Researchers from the University of Glasgow and University of Birmingham have developed a prototype liquid crystal lens that can block over 98% of light in the 660–720nm wavelength range, which is known to trigger seizures in people with photosensitive epilepsy. The lenses are controlled by small temperature changes and can be integrated into glasses, potentially helping patients avoid seizures in environments with triggering light, such as while watching TV or playing video games. Further development is needed to enhance performance and adapt to different temperatures.
