Hypermetropia \Hy`per*me*tro"pi*a\, Hypermetropy
\Hy`per*met"ro*py\, n. [NL. hypermetropia, fr. Gr. ? excessive +
?, ?, the eye. See {Hypermeter}.]
A condition of the eye in which, through shortness of the
eyeball or fault of the refractive media, the rays of light
come to a focus behind the retina; farsightedness; -- called
also {hyperopia}. Cf. {Emmetropia}.
Note: In hypermetropia, vision for distant objects, although
not better absolutely, is better than that for near
objects, and hence, the individual is said to be
farsighted. It is corrected by the use of convex
glasses. -- {Hy`per*me*trop"ic}, a.
