What happens to the image distance in the eye when we increase the distance of and object from the eye?

Answer»

When we increase the distance of an object from the eye , the image distance in the eye does not change. DUE to POWER of accommodation of the eye, focal length of the eye LENS is changed which compensates the increase in object distance. Image distance remains fixed and image is formed on the retina of the eye.Mark as BRAINLIST MATE
