Sign in to saveAlso known as hypermetropia, far-sightedness
Far-sightedness, also known as long-sightedness, hypermetropia, and hyperopia, is a condition of the eye where distant objects are seen clearly but near objects appear blurred. This blur is due to incoming light being focused behind, instead of on, the retina due to insufficient accommodation by the lens. Minor hypermetropia in young patients is usually corrected by their accommodation, without any defects in vision. But, due to this accommodative effort for distant vision, people may complain of eye strain during prolonged reading. If the hypermetropia is high, there will be defective vision
Hyperopia, commonly called far-sightedness, is a condition where your eyes focus light behind the retina instead of directly on it, making nearby objects appear blurred while distant ones stay clear. It matters because while mild cases may go unnoticed due to your eye's natural focusing ability, severe hyperopia causes blurred vision and eye strain during close-up activities like reading.

Hipermetropia ou hiperopia é uma condição do olho em que a luz é focada na parte posterior da retina, ao invés da própria retina. Isto faz com que a pessoa veja desfocados os objetos a curta distância, enquanto os objetos distantes são vistos normalmente. À medida que a condição se agrava, é possível que se comece a ver os objetos desfocados a qualquer distância. Entre outros sintomas comuns estão dores de cabeça e astenopia. Algumas pessoas podem também manifestar disfunção de acomodação, disfunção binocular, ambliopia e estrabismo. É um tipo de erro refrativo. A hipermetropia é causada por uma imperfeição dos olhos. Geralmente ocorre quando o globo ocular é muito curto, ou então quando existem um defeito na forma do cristalino ou da córnea. Entre os fatores de risco estão antecedentes familiares da doença, diabetes, alguns medicamentos e tumores nas proximidades do olho. O diagnóstico tem por base um exame ocular. O tratamento consiste na utilização de óculos ou lentes de contacto ou na correção cirúrgica. Embora os óculos sejam o método de correção mais simples, as lentes de contacto oferecem um maior campo de visão. A correção cirúrgica consiste na alteração da forma da córnea. A hipermetropia afeta inicialmente as crianças mais novas, com taxas de prevalência de 8% aos seis anos de idade e de 1% aos 15 anos de idade. Depois volta a ser comum a partir dos 40 anos de idade, afetando cerca de metade das pessoas.
