Long-sightedness, or hyperopia, is a sight problem that affects your ability to see near objects. People who are long-sighted often see distant objects clearly, but nearby objects appear blurred. Long sight occurs when light is not able to focus before or on the retina. Long sight generally occurs when the eye does not grow enough and is too short from the front to the back. Some children are born with long sightedness, although this can correct itself as their eyes and visual pathways develop, some cases may run in families. Long sight can be corrected with glasses or contact lenses.
