Answer:
The ciliary muscles of our eyes are unable to contract after a certain point. If the object is placed at a distance less than 10 cms from our eyes, then it will be reflected beyond the retina making it blurry for the viewer. This happens because the light rays emitted are emitted to a point other than the focal point.
