This document discusses hypermetropia (farsightedness), where parallel rays from infinity are focused behind the retina when the eye is at rest. There are several types of hypermetropia based on etiology, including axial (most common, due to short axial length), curvatural (flattened cornea or lens), and index (increased refractive index). Symptoms range from asymptomatic to asthenopia (eye strain) and defective vision. Treatment includes optical correction with glasses or contacts, as well as surgical options like refractive surgery or phakic IOL implantation. Proper visual hygiene from an early age can help prevent complications like amblyopia.
