hypermetropia:a condition of the eye in which parallel rays are focused behind theretina, distant objects being seen more distinctly than near ones;farsightedness (opposed to myopia ).
Myopia is inherited and is often discovered in children when they are between ages eight and 12 years old. During the teenage years, when the body grows rapidly, myopia may become worse. Between the ages of 20 and 40, there is usually little change. Myopia can also occur in adults.
