__Biconcave Lens__

A biconcave lens is a type of lens that is thinner at the center and thicker at the edges. It is concave on both sides, giving it a curved inward shape. These lenses are used in optics to help correct nearsightedness and other vision problems. The shape of the lens allows it to diverge incoming light, making distant objects appear clearer to the eye.


A lens is a transparent object that refracts or bends light, allowing it to focus. Convex lenses converge light, while concave lenses diverge it. Lenses are crucial in eyeglasses, cameras, and microscopes for vision correction and image magnification.
