| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. Hyperopia, also
known as farsightedness, longsightedness or hypermetropia, is a defect
of vision caused by an imperfection in the eye (often when the eyeball
is too short or the lens cannot become round enough), causing difficulty
focusing on near objects, and in extreme cases causing a sufferer to be
unable to focus on objects at any distance. As an object moves toward
the eye, the eye must increase its optical power to keep the image in
focus on the retina. If the power of the cornea and lens is
insufficient, as in hyperopia, the image will appear blurred. |
