What is far sighted?

Far-sighted can mean:

1) able to plan ahead

2) a vision disorder in which you can't see up close.

A definition is "unable to see things clearly, especially if they are relatively close to the eyes, owing to the focusing of rays of light by the eye at a point behind the retina. The adjective is hyperopic.

The opposite, near-sighted (nearsighted) means that you cannot see distant objects clearly.
