hypermetropia
n 1: abnormal condition in which vision for distant objects is
better than for near objects [synonym: {hyperopia},
{hypermetropia}, {hypermetropy}, {farsightedness},
{longsightedness}] [ant: {myopia}, {nearsightedness},
{shortsightedness}]

Hyperopia \Hy`per*o"pi*a\ (h[imac]`p[~e]r*[=o]"p[i^]*[.a]), n.
[NL., fr. Gr. "ype`r over 'w`ps, 'wpo`s, the eye.]
An abnormal 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, making vision for
distant objects better than for near objects; farsightedness;
-- called also {hypermetropia}. Cf. {Emmetropia}. --
{Hy`per*op"tic}, a.

Syn: hypermetropia, farsightedness, longsightedness.
[1913 Webster]


Hypermetropia \Hy`per*me*tro"pi*a\, Hypermetropy
\Hy`per*met"ro*py\, n. [NL. hypermetropia, fr. Gr. ? excessive
?, ?, the eye. See {Hypermeter}.]
An abnormal 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, making vision for
distant objects better than for near objects; farsightedness;
-- now most commonly called {hyperopia}. Cf. {Emmetropia}.
[Obsolescent]

Syn: hyperopia, farsightedness, longsightedness.
[1913 Webster]

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.
[1913 Webster]
