En quoi consiste l’hypermétropie?

Si vous avez déjà vu un ami ou un proche âgé tenir un livre au bout de ses bras pour arriver à le lire, cette personne souffrait probablement d’hypermétropie.

Les personnes hypermétropes voient clairement les objets éloignés, mais ont de la difficulté à voir les objets rapprochés. Comme la myopie, l’hypermétropie est un défaut de l’œil. La distance entre l’avant et l’arrière du globe oculaire est trop courte et le cristallin a de la difficulté à s’arrondir suffisamment pour faire la convergence. Cela donne des images qui se font derrière la rétine, la zone qui « traite » les images visuelles.

L’hypermétropie est un problème courant de la vue, plus susceptible d’apparaître avec l’âge. Il est habituellement facile de traiter l’hypermétropie au moyen de verres correctifs ou de lentilles cornéennes.

Farsightedness Symptoms:

Symptoms of farsightedness include eyes that feel tired or strained, headaches, squinting and blurred vision, especially when viewing objects that are near. But symptoms can vary person to person based on the degree of farsighted vision; some may notice little visual impairment, while others may have blurred or hazy vision for objects at distance and nearby.

Farsighted vision can develop at any time, and happens in both children and adults. Farsightedness develops when the eyeball becomes “shorter” than it should be, moving the “focal point” of the images we see from on top of the retina, to behind the retina. Abnormalities in the eye’s lens or cornea can also cause farsighted vision.

Farsighted Diagnosis and Treatment:

Only an eyecare professional can accurately detect, diagnose and treat farsightedness. That’s why routine comprehensive eyecare exams are so important to maintaining healthy vision and healthy sight.

Farsighted vision is treated by helping the eyes focus images correctly on the retina, rather than behind it. This is done by prescribing eyeglasses, contact lenses or through a number of forms of surgery that help to reshape the surface of the eye.

Each treatment option has benefits and drawbacks that should be discussed completely with an eyecare professional.
