What happens to the image distance in the normal human eye when we decrease the distance of an object, say 10 m to 1 m? Justify your answer.
If the object distance is greater than 25 cm the image is always formed on the retina as the focal length of the human eye lens gets adjusted depending on the object distance. This special property of the human eye is called as power of accommodation. Hence, image distance will remain the same if object distance changes from 10 m to 1 m.
