Far Sightedness Hypermetropia
Far Sightedness Hypermetropia
Far-sightedness (Hypermetropia): Some people cannot see nearby objects clearly, although they can see distant objects clearly. This defect is called far-sightedness, long- sightedness, hypermetropia or hyperopia. It arises mainly due to two reason
People suffering from far-sightedness have difficulty in reading a book or a newspaper, or viewing a small object placed close to the normal near point, N (at 25 cm). People suffering from far-sightedness have to keep reading material or an object much farther away to see clearly. In other words, their near point, N', is farther than the normal near point, N Correcting far-sightedness: To see an object placed at the normal near point, N, clearly, its sharp image should be formed on the retina. For this, the rays should seem to be coming from N', the near point of the defective eye. To do this, the rays are made less divergent by placing a convex lens in front of the eye as in figure (c). Rays of light coming from N pass through the convex lens. When produced backwards, the emergent rays meet at the point N'. Thus, a sharp image is formed on the retina.
