Which type of lens is a natural lens present in the human eye?

Correct option is A

The correct answer is (a) Convex.
· The natural lens present in the human eye is a convex lens. A convex lens is thicker at the center than at the edges, which allows it to converge light rays to a focal point. In the human eye, the convex lens focuses light onto the retina, enabling us to see clear and sharp images.
Information Booster:
· Concave Lens: Thinner at the center than at the edges, used to diverge light rays, typically used to correct short-sightedness (myopia).
· Bifocal Lens: A type of lens with two different optical powers, commonly used in eyeglasses for correcting both near and distance vision.
· Progressive Lens: A type of multifocal lens used in eyeglasses that provide a gradual transition from distance to near vision correction, without visible lines.
