What is a convex lens?
A convex lens is a lens where the thickness is maximum at the center and minimum at the periphery. It is a converging lens that converges the parallel light rays towards the center and intersects at the focal point. The focal length is the distance between the focal point and the optical center. The convex lens can form real and inverted images or virtual and erect images based on the object's position. It is utilized in eyeglasses for farsighted individuals to aid in focusing on the retina.
