Oversightedness is a visually impairing condition also known as Hypermetropia or ‘long-sightedness. Eyesight problems, such as oversightedness, are also known as refractive errors. It leads to problems such as near vision, and the eyes may commonly become tired. Distance vision (long sight) is, in the beginning, often clear. It can be corrected by glasses or contact lenses, or sometimes ‘cured’ with laser eye surgery.
Mild oversightedness is frequently and usually found in the majority of young children. It gradually ceases to exist in a large number of children when they reach adulthood.
What are the symptoms?
In the young, because of the reserve capacity of the eye, there may be no symptoms.
At a later age, the main complaints are of continuously nagging headache and strain. The main problems are burning of the eyes during close work, especially in the evenings by artificial illumination. The eye tends to become red and the front of the head pains. The eye may also ache and feel dry.
In older people, usually after the age of 38 years, as the capacity to accommodate near work fails, the reading material is held farther away from the eye than comfort or good vision dictates, and the condition is then called presbyopia.
How do you control?
In order correct the condition, a plus lens is required so that the light can now focus on the retina. It is important to give the exact amount of plus correction as any excess will again lead to problems.
