What changes take place in the shape of eye-lens : (a) when the eye is focused on a near object ? (b) when the eye is focused on a distant object ?

The focal length of a normal eye lens is about

For a normal eye, the least distance of distinct vision is

For a normal eye, distance of near point from the eye is.

The focal lengths of the objective and the eye-piece of an astronomical telescope are 0.25 m and 0.025 m, respectively. The telescope is focussed on an object 5m from the objective, the final image being formed 0.25 m from the eye of the observer. Calculate the length of the telescope and its magnifying power.

Assertion: The image distance in the eye increases, when we increase the distance of an object from the eye. Reason: For normal eye, image distance in the eye is fixed, being equal to distance of retina from the eye lens. The focal length of the eye lens is changed on account of accommodation power of the eye.
