A flat lens is a lens with minimal curvature across its surface. Instead of bending light strongly, it creates gentle changes in direction. Flat lenses appear in protective shields, eyewear accessories, and some specialty optics. They help maintain wide fields of view without adding magnification. Their simple shape makes them useful in tools requiring clarity without distortion.
