ⓘ Far-sightedness

Far-sightedness, also known as hypermetropia, is a condition of the eye in which light is focused behind, instead of on, the retina. This results in close objects appearing blurry, while far objects may appear normal. As the condition worsens, objects at all distances may be blurry. Other symptoms may include headaches and eye strain. People may also experience accommodative dysfunction, binocular dysfunction, amblyopia, and strabismus.

The reason is the imperfection of the eye. Often this occurs when the eyeball is too short or the lens or cornea is distorted. Risk factors include family history of the disease, diabetes, certain medications, and tumors around the eyes. This type of refraction. The diagnosis is based on the eye exam.

The management can happen with the help of glasses, contact lenses or surgery. Glass is easy as contact lenses can provide a wider field of view. The surgery works by changing the shape of the cornea. Farsightedness primarily affects young children, with rates of 8% in 6 years and 1% for 15 years. He then becomes even more common after the age of 40, affecting about half of the people.
