Liquid crystal lens

A liquid crystal lens is an optical device that uses liquid crystals to change its shape or focus. Unlike traditional lenses, which are fixed in curvature, liquid crystal lenses can adjust their properties when an electric current is applied. This allows them to quickly focus on objects at varying distances, making them useful in advanced optical applications such as camera systems, eyeglasses, and displays. Their ability to rapidly change focus enhances image clarity and depth, offering potential improvements in visual technologies.
