Scientists at the University of Glasgow and Birmingham (UK) have recently announced a trial of a special type of glasses that can prevent light-induced seizures in individuals with light-sensitive epilepsy.

According to the announcement in the journal Cell Reports Physical Science, the lenses are made from liquid crystals and can block up to 98% of light in the wavelength range of 660-720nm, which has been identified as the cause of seizures in most patients with light-sensitive epilepsy.
Professor Zubair Ahmed, a neurologist at the University of Birmingham and co-author of the study, stated: “This is an incredibly exciting project. Four years ago, when we started, we thought this was a science fiction idea. Now, we have demonstrated the potential of using liquid crystal lenses to filter specific light wavelengths.”
The mechanism of the glasses is based on a compact circuit integrated into the frame, which controls the temperature of the lenses. When activated, the lenses maintain a moderate temperature, providing comfort for the wearer while effectively blocking light that could trigger seizures, especially useful when watching TV or playing video games.
Professor Rami Ghannam, an electronics expert at the University of Glasgow and the lead author of the study, emphasized: “This project shows that collaboration between engineering, neurology, and mathematics can lead to innovations that significantly improve the lives of patients.” However, the current trial lenses only function effectively at room temperatures up to 26°C. The research team stated that they are continuing to improve the performance and temperature adjustment speed of the glasses before proceeding with human trials.
