| For the nearsighted
eye, objects at a far distance are not focused correctly.
The different components of the nearsighted eye are not precisely in
tune. The refractive power of the cornea is too high, or the eye is
too long, respectively, and the light rays come to focus in front of,
rather than on, the retina, thereby resulting in an unfocused and blurry
image on the retina itself. This is shown in the figure below.
