Question

What is the lens of the eye?

Answer 1

1. Behind the iris of the eye is a biconvex, translucent structure called the lens.
2. The lens' job is to refract light so that it can be focused on the retina.
3. The focal length of the eye is changed by changing the curvature of the lens, allowing the eye to focus clearly on things at different distances.
4. The capacity of a lens to change from a wide to a close focus is referred to as accommodation.
5. Two spherical surfaces make up the optical lens.
6. The biconvex lens is formed when the spherical surfaces bulged outwards.
7. Two convex lenses with the same radius of curvature make up a biconvex lens.
8. The ray of light converges and focuses at a point on the other side of the convex lens.
9. This point is known as the focus, and the focal length is the distance between the lens's centre and the focus.

Hence, the lens of the eye is a biconvex lens.
