Lenses are useful for moving light because they can bend and focus light rays through refraction, allowing for the manipulation of light paths. This bending occurs as light passes through the curved surfaces of the lens, enabling applications such as magnification, image formation, and correction of vision. By altering the direction and convergence of light, lenses play a crucial role in optical devices like cameras, microscopes, and eyeglasses.
