It is a disorder caused by a defect of refraction in which rays of light entering the eye converge to a focus behind the retina. In other words, is the condition commonly associated with trouble seeing close up.
1. What is it?
In this case, and in contrast to myopia, the eye focuses the image behind the retina. By focusing the images in this way, the distance vision is clearer than the nearby. This refractive error is usually because the eye is too short or that your lens system is very weak.
2. Symptoms
If the hyperopia is not very intense usually affects only the near vision, especially problems causing headaches or eyestrain.
3. Treatment
For young people can compensate for the hyperopia by accommodation and hence a good look at both distance and near. This extra effort can cause eye fatigue, which is higher the closer the object.
With age diminishes the capacity of accommodation and therefore the possibility to compensate the defect of vision through it. With the same amount of farsightedness and vision will be worse the person will need glasses to see well.
However, if the defect is severe, the mechanisms that have the eye to correct the insufficient regardless of the age of the person and vision will be defective in both far and near.
