Question

What are the limits to change the focal length of eye lens? (1/2mark)​

Answer 1

Explanation:

when the object is at infinity, the parallel rays from the object falling on the eye lens are refracted. They form a point-sized image on retina. In this situation, eye lens has a maximum focal length

Answer 2

The image distance in the eye, is fixed and cannot be changed. The ability of the eye lens to adjust its focal length is called accommodation. Due to this eye can increase or decrease focal length of the lens in order to see either close or distant objects.
