__Biconvex Lens__

A biconvex lens is a type of lens that is thicker at the center and thinner at the edges. It is convex on both sides, giving it a curved outward shape. Biconvex lenses are used in optics to help correct farsightedness. The shape of the lens allows it to converge incoming light, making nearby 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.
