Researchers from the University of Glasgow and the University of Birmingham have developed an innovative prototype of glasses designed to assist individuals with photosensitive epilepsy by blocking light wavelengths that induce seizures. Featuring liquid crystal lenses, the glasses are capable of blocking over 98% of harmful light in the 660-720nm wavelength range, significantly diminishing seizure risks during everyday activities such as watching television or playing video games.
This breakthrough technology utilizes a discrete circuit within the glasses’ frames that regulates the lens temperature, activating the light-filtering properties for the wearer’s safety. The collaborative effort between experts in engineering, neuroscience, and mathematics has made significant advancements in epilepsy management.
While the current prototype is effective at temperatures up to 26°C, improvements are ongoing to enhance performance and expand functionality for hotter environments. The researchers are also focused on refining the heating and cooling time of the lenses before advancing to human trials. This development marks a promising step towards improving the quality of life for individuals affected by photosensitive epilepsy, showcasing the potential of multidisciplinary research in creating transformative healthcare solutions.
