Hipermetropie - Wikipedia

Hipermetropia (sau hipermetropismul) este o afecțiune a ochiului, caracterizată prin formarea imaginii în spatele retinei, ceea ce face ca imaginea să devină încețoșată.. Hipermetropia apare când diametrul antero-posterior al globului ocular este mai mic decât normal. În esență, hipermetropia se datorează unui viciu de refracție, caracterizat printr-un deficit de convergență.
Mise en garde médicale modifier - modifier le code - voir Wikidata (aide) L' hypermétropie est un trouble de la vision . D'un point de vue optique pur, l'hypermétropie est le contraire de la myopie: quand l'œil est au repos, il donne d'un objet distant une image qui serait focalisée en arrière de la rétine. L'œil hypermétrope est donc un œil dont le système optique n'est pas assez.

Hipermetropia ou hiperopia é uma condição do olho em que a luz é focada na parte posterior da retina, ao invés da própria retina. [1] Isto faz com que a pessoa veja desfocados os objetos a curta distância, enquanto os objetos distantes são vistos normalmente. [1] À medida que a condição se agrava, é possível que se comece a ver os objetos desfocados a qualquer distância. [1

Verziendheid (hypermetropie, hypermetropia) is een oogafwijking waarbij een persoon zonder accommodatie van het oog niet scherp kan zien.. Verziendheid wordt veroorzaakt door een te korte oogas of een te geringe sterkte van het brekend stelsel van het oog (hoornvlies plus ooglens), waardoor het beeld van voorwerpen 'achter het netvlies' gevormd wordt.

Bei der allgemeinsprachlich Weitsichtigkeit genannten Übersichtigkeit (Synonym: Hyperopie oder Hypermetropie) handelt es sich um einen sogenannten axialen Brechungsfehler des Auges (), bei dem der Augapfel im Verhältnis zur Brechkraft seiner optischen Einrichtung zu kurz beziehungsweise die Brechkraft zu gering ist. Dies führt dazu, dass sich die Bildlage für optisch unendlich weit.

Hypermetropi, (hyperopi) eller langsynthet er en vanlig synsfeil som innebærer at øyet er for kort i forhold til lysbrytningen i hvileposisjon. Den gjør det vanskelig å se klart på nært hold. Graden av langsynthet kan variere, og korrigeres med briller eller kontaktlinser med plusstyrke Near-sightedness, also known as short-sightedness and myopia, is an eye disorder where light focuses in front of, instead of on, the retina. This causes distant objects to be blurry while close objects appear normal. Other symptoms may include headaches and eye strain. Severe near-sightedness is associated with an increased risk of retinal detachment, cataracts, and glaucoma Nadwzroczność (popularnie: dalekowzroczność; łac. hyperopia; często mylona ze starczowzrocznością) - druga obok krótkowzroczności najczęściej spotykana wada refrakcyjna wzroku.Jest wynikiem zbyt małych rozmiarów przednio-tylnych oka (zbyt krótką gałką oczną) w stosunku do jego siły łamiącej lub niewystarczającą siłą łamiącą układu optycznego oka (np. zbyt.

Hyperopia (also called hypermetropia or far-sightedness) is a problem with the focusing ability of the eye.People with hyperopia have an easier time seeing things that are far away than seeing things that are up close. Inside the eye is the lens which can change shape to change the focusing power of the eye and make things look clear. Someone who is not far-sighted only needs to use their lens. hypermetropia An inherent, dimensional eye defect in which neither distant nor near objects can be seen clearly when the eye in a state of relaxed focus. Vision can be clarified by ACCOMMODATION and this is easy for the young, who are often unaware of hypermetropia. As the power of accommodation falls off with age, however, 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. Visual acuity is better at far (e.g. 6 meters) distances than at near (e.g. 0.33 meters) distances[1

What is simple hypermetropia? This type of hypermetropia is commonly seen. It is usually a continuation of the childhood hypermetropia which has not regressed with time. Most normal infants when they are born have a hypermetropia of plus 4 dioptres. This is due to a variety of factors though the main reasons are a shorter eye and a forward.

We found that out in children with ametropia, 20 (35.7%) had myopia, 24 (42.8%) had astigmatism and 12 (21.5%) had hypermetropia.This is in accordance with prevalence found by studies showing that low degrees of astigmatism and anisometropia are relevant in migraine and headache.20 In another study conducted in Israel, it was found that anisometropia and myopia were the most common refractive.
Curvature hypermetropia: Curvature hypermetropia is that condition in which curvature of the cornea, lens or both is increased (flatter) than the normal, resulting in change in refractive power of the eye. About 1 mm increase in radius of curvature results in 6 D of hypermetropia
