When the object is near , the focal length of the eye lens is increased and the rays from the object are converged on the retina. In the eye, the image distance (distance between eye lens and retina) is fixed and cannot be changed. So when we increase the distance of an object, there is no change in the image distance.

Explanation:

Introduction:
When an object is placed at a certain distance from the eye, an image is formed on the retina which allows us to see the object. The distance between the object and the eye is known as the object distance, and the distance between the image and the eye is known as the image distance.

Understanding the concept:
To understand how the image distance changes as we increase the object distance, let's consider a simple case of a magnifying glass. When we bring the magnifying glass closer to our eye, the image formed on the retina becomes larger. Conversely, when we move the magnifying glass away from our eye, the image becomes smaller. This happens because the focal length of the magnifying glass remains constant, but the distance between the object and the magnifying glass changes.

Explanation:
When we increase the distance of an object from the eye, the image distance remains the same. This is because the image distance is determined by the focal length of the lens or the distance between the lens and the retina. As long as this distance remains constant, the image distance will also remain constant.

Example:
For example, let's say we are looking at an object that is 1 meter away from our eye. The image distance will be determined by the focal length of the lens in our eye and will be a certain value. Now, if we move the object further away, let's say 2 meters, the image distance will still be the same because the focal length of the lens has not changed.

Conclusion:
In conclusion, as we increase the distance of an object from the eye, the image distance remains the same. This is because the image distance is determined by the focal length of the lens or the distance between the lens and the retina, which does not change when the object distance is changed.
