Solution - What Happens to the Image Distance in the Eye When We Increase the Distance of an Object from the Eye? - CBSE Class 10 - Science

ConceptDefects of Vision and Their Correction

Question

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

Solution 1

The image is formed on the retina even on increasing the distance of an object from the eye. For this eye lens becomes thinner and its focal length increases as the object is moved away from the eye.

Solution 2

Since the size of eyes cannot increase or decrease, the image distance remains constant. When we increase the distance of an object from the eye, the image distance in the eye does not change. The increase in the object distance is compensated by the change in the
focal length of the eye lens. The focal length of the eyes changes in such a way that the image is always formed at the retina of the eye.
