Answer:

As a result, collimated rays focus short of the retina, and the second focal point lies within the vitreous (Fig. 14b). To compensate for this excessive power of the eye, the object must be brought closer.

Explanation:

The focal length of the average, healthy, adult human eye at near-point is about 18.5 mm. Young individuals can accommodate their lenses further to a focal length of around 15.4 mm. The focal length of the human eye is the distance between the lens and the retina when an object is in focus

The cornea, a clear window at the front of the eye, covers the iris and the pupil. A clear lens, located behind the pupil, acts like a camera lens by focusing light onto the retina at the back of the eye. The retina is a light-sensitive inner lining at the back of the eye.
