Nearsightedness and Farsightedness Definition
In an eye with normal vision, focusing ability of the cornea and lens is matched to the length of the eye. Your eyes are therefore able to focus an image precisely on the retina.
In nearsightedness, or myopia, vision is better up close than at a distance.
In farsightedness, or hyperopia, vision is often better at a distance than up close (although it may be blurry both at a distance and up close).
