plano lens

A plano lens is a type of optical lens that has a flat surface on one side and a curved surface on the other, or it can be completely flat with no curvature. These lenses are commonly used in eyeglasses and optical instruments when no magnification or correction is needed. Plano lenses protect the eyes from dust, debris, or UV rays without altering vision. They are also used in various scientific and industrial applications where light needs to pass through without distortion.
