Lens

A lens is an optical element made of transparent material whose surface is part of a spherical surface. Lenses are transparent materials with one or more curved surfaces made of optical materials such as glass or resin. After grinding, they are often assembled with spectacle frames to form spectacles to correct the user's vision, obtain a clear vision or obtain functional assistance. According to different materials, lenses are divided into glass lenses, resin lenses, PC lenses (polycarbonate lenses), and so on.
