There are two types of refractive problems of farsightedness and nearsightedness. Myopia is a condition where a person can not see objects clearly, but you can clearly see close objects.
The opposite occurs in people who suffer from nearsightedness, the objects closer to vision, but distant objects are clearly visible.
Some children suffer from symptoms of myopia can be easily identified.
Often, reading a book close to distant objects, such as television, see to reduce both eyes, so that the object more clearly.
Source of myopia

The possibility of a child whose parents suffer from myopia, the same problem 40 peratus.Ada theory, farsightedness occurs when a person like say dekat.Sesetengah read from other experts, to break that jauhlah reading distance range.
Shortness of breath is not a malfunction. In fact, the structure of the eye sighted normal.Apa it happens, more and more people that do not get, rabun.Imej The eye can not focus on the retina, but focused on a position in front of the retina.
This situation is comparable to the human differences curly hair straight, worn a few glasses and some not mata.Tahap with the myopia has not changed or increased by more glasses.
In fact, if you do not wear glasses, myopia increased level every six months, when the glasses should be changed.

At the close of the curing process is difficult to see the ability to objects blown eyes. This problem must be overcome to wear reading glasses, to be held every two years.
To determine if a person suffers from presbyopia, a blurred spot in both eyes and the sharpness of the object is more pronounced when the object is saved far less. Also, they should not be confused with the problem of acts of Qatar, especially among people over 40 years.
People with cataracts have difficulty seeing far away. A person with cataracts can not clearly see distant objects and object is blurred, even with glasses.
