| Causes and risk factors |
|
Hypermetropia is due to genetic causes. It is due to too short eye ball or due to a flat cornea as a result the image gets focused at a point behind the retina. Due to this there is difficulty in focusing objects at less distance.
When any object moves towards the eye, the eye has to increase its power to keep the image in focus on retina. When the power of lens and cornea is not enough there is a formation of a blurred image. This is called as hypermetropia. In this the image is formed behind the retina.
Having family members with hypermetropia is a risk factor for hypermetropia.
