Solution
The correct option is A The image distance from the eye lens
By using the power of accommodation, the radius of curvature of the eye lens changes which changes the focal length, when we see objects at different distances, i.e. for different object distances.
Whereas, the image distance from the eye lens remain constant since, the image is always formed on the retina and the distance between eye lens and the retina is fixed.
