Hypermetropia is also known as long sightedness. This means the eyeball is too short so the light and image is focused behind the retina and not on it.
People who are long sighted have problems seeing things close up and in extreme cases they also have problems with distance. They can suffer with eye strain, headaches, and tiredness.
In most cases treatment will depend on symptoms and age. Spectacles and contact lenses are the usual form of correction but some forms of refractive surgery may be suitable. Hypermetropia is corrected with plus (+) lenses which have thinner edges and a thicker middle.
