hypermetropia    
n. 远视

远视

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]

  • Hypermetropia (Long-Sightedness): Symptoms, and Treatment - Patient
    The medical name for long-sightedness is hypermetropia, sometimes called hyperopia Eyesight problems, such as hypermetropia, are also known as refractive errors Long-sightedness leads to problems with near vision (seeing things that are close up) and the eyes may commonly become tired
  • Farsightedness - Wikipedia
    Total hypermetropia: It is the total amount of hyperopia which is obtained after complete relaxation of accommodation using cycloplegics like atropine Latent hyperopia : It is the amount of hyperopia normally corrected by ciliary tone (approximately 1 diopter)
  • Farsightedness - Symptoms and causes - Mayo Clinic
    Farsightedness (hyperopia) is a common vision condition in which you can see distant objects clearly, but objects nearby may be blurry The degree of your farsightedness influences your focusing ability
  • Hypermetropia : Facts, onset, types, diagnosis, treatment | FactDr
    Hypermetropia is an eye problem where a person has difficulty viewing objects close to him, but can clearly see the objects located far away This happens due to the light being focussed behind the retina instead of being focused on it
  • What is Hypermetropia (Long-sightedness)? Causes, Symptoms and . . .
    If so, you might be experiencing hypermetropia, also known as long-sightedness In this article, we’ll explore the causes, symptoms, and treatment options for hypermetropia, giving you the knowledge you need to understand and manage this condition
  • Hypermetropia: Causes, Symptoms Treatment - Laxmi Eye Hospital
    Hypermetropia, commonly known as farsightedness, is a refractive error where distant objects are seen more clearly than nearby objects
  • Hypermetropia (Long-Sightedness): Causes and Treatment - OCL Vision
    Understanding hypermetropia (long-sightedness): symptoms, causes and treatments Hypermetropia occurs when the power of the eye is insufficient or the eye is too short, causing light rays to focus behind the retina rather than directly on it
  • Causes of Hypermetropia: Understanding Farsightedness
    Hypermetropia is a refractive error that occurs when the eyeball is shorter than normal or the cornea is flatter than usual This causes light entering the eye to focus behind the retina instead of directly on it, resulting in blurred vision for nearby objects
  • Farsightedness: What Is Hyperopia? - American Academy of Ophthalmology
    Farsightedness is an eye focusing disorder, not an eye disease What Causes Farsightedness? To see clearly, light rays must travel through the front of the eye (the cornea and lens) The cornea and lens work together to bend the light so it lands on the back layer of the eye, called the retina
  • Hyperopia - EyeWiki
    Hyperopia is also known as “farsightedness” or “hypermetropia” It is an ocular condition in which the refracting power of the eye causes light rays entering the eye to have a focal point that is posterior to the retina while accommodation is maintained in a state of relaxation
