Document Summary
Hyperopia (farsightedness): is a vision condition in which distant objects are usually seen clearly but close ones do not come into proper focus. This occurs if your eyeball is too short or the cornea has too little curvature, so light entering your eye is not focused correctly. Myopia (nearsightedness): is a vision condition in which people can see close objects clearly, but objects father away appear blurred. This occurs if the eyeball is too long or the cornea is too curved. As a result, light entering the eye isn"t focused correctly and distant objects look blurred. Myopia can be corrected with an appropriate concave-surface lens. It is the leading cause of visual impairment with vision loss ranging from mild to severe: diplopia: (double vision, nystagmus: involuntary, rapid, rhythmic eye movements. These movements often result in reduced vision and depth perception and can affect balance and coordination. Both eyes are unable to steadily view objects.
