IXI is developing lightweight, autofocusing glasses that use eye tracking and liquid crystal lenses to automatically switch focus, potentially replacing multifocal glasses and offering new health insights, with a planned launch next year.
IXI is developing smart glasses with liquid crystal lenses that can automatically adjust focus in real-time, aiming to improve vision correction for conditions like presbyopia and myopia, while emphasizing the importance of aesthetic appeal and user acceptability. The technology is still in trials, with potential to revolutionize eyewear, though safety and performance concerns remain.
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.
