The eye with long-sightedness (hyperopia) is “too short” (measured from the front to the rear). In rare cases, an eye will have poorer focusing of the image with the cornea and the lens. In both cases, the images of objects (regardless of distance) are sharpened behind the retina, and the images taken by the brain are blurred. Images of close objects are even more blurred, which often seriously affects the near vision (e.g. when reading).
Long-sightedness is usually present since birth, and is usually diagnosed after the child begins to complain of eye fatigue; as well as short-sightedness, the long-sightedness is often inherited.
Many people with this condition do not feel any symptoms. Others feel the eye fatigue (pain or uneasy feeling in the eye) since they have to constantly tighten the cervical muscles for sharpening the image and clear vision. People with moderate or severe long-sightedness have a constantly blurry vision, and can also feel eye fatigue. Although none of these symptoms can permanently damage the vision, early treatment is recommended.
What to do?
If you suffer from blurry vision or eye fatigue, contact the ophthalmologist. If the ophthalmologist finds that you have long-sightedness, he will prescribe your glasses (or contact lenses) with convex lenses. Such lenses enhance the power of forcusing of the cornea and lens in the eye, enabling you to see clearly, thus eliminating eye fatigue.
With age it may come to weakening of cillary muscles, so you may need stronger lenses every few years.
