Liquid Crystal Lens Filters out Light that Causes Seizures
GLASGOW, Scotland, Nov. 26, 2024 — In people who experience photosensitive epilepsy, seizures can be triggered by visual stimuli, like video games, that are displayed at certain wavelengths. Lenses made with cholesteric liquid crystal (CLC), a material that is sensitive to changes in temperature as well as the electrical field, could help block these harmful wavelengths through thermal control. The CLC lenses are the result of a collaboration between the University of Glasgow and the University of Birmingham. “The
