what is the difference between being near sighted and far sighted?

Location of focus: Near sighted means you see better at near and your distance vision is blurry. Far sighted is just the opposite. In near sighted eyes, the image is brought into focus in front of the retina and a diverging lens is needed to push the image backward to focus on the retina. In a far sighted eye, the image is focused behind the retina and a converging lens is needed to bring the image forward.

A 35-year-old member asked:

What sort of disorder is farsightedness?

A refractive error: A "farsighted" person has an eye too short for the optics. This means their cornea + lens cannot bend the light enough to focus on a point on the back of the eye. To correct this, they need eyeglasses which assist in light bending, a type of magnifying glass. The eyeglass of a farsighted person will focus light to a point (a myopes glasses spreads the light).

Convex lens: The farsighted (hyperopic) eye is too short. The rays of light entering the eye are not bent sharply enough to converge and form an image on the retina; rather, the image is formed behind the retina. A convex lens (shaped like a magnifying glass) adds some light-bending so the rays are bent more sharply, and the image is formed on the retina. A picture of this is much clearer.

Depends :-): It could be a complement due to your ability to anticipate the future. Far more likely, you can it means you see things at a distance better than you can see things at close range. Ieither your eyeball is too short and the focal point for light lands behind your retina, or the lens in your eye lacks focusing power. Under 40, may self correct. May be symptomless. It is treatable with corrective.
