Hyperopia – Farsighted
Farsighted people usually see distant objects more clearly than close objects. Farsightedness is caused by any combination of a short eyeball and flat corneal curvature. In this case, light hits the retina before it can come into sharp focus.
Hyperopia, unlike normal vision, occurs when the cornea is too flat in relation to the length of the eye. This causes light to focus at a point beyond the retina, resulting in blurry close vision and occasionally blurry distance vision as well. Usually this condition is undetected until later in life because the young eye is able to compensate for the hyperopia by contracting the internal lens of the eye.
Symptoms of hyperopia:
- Blurry close vision
- Occasionally, blurry distance vision
Causes of hyperopia:
Many people are not diagnosed with hyperopia without a complete eye exam. School screenings typically do not detect this condition because they test only for distance vision. Your eye doctor can conduct a refractive evaluation to determine whether your eyes focus light rays exactly on the retina at distance and near. A visual acuity test will determine your ability to see sharply and clearly at all distances. Your eye doctor will also check your eye coordination and muscle control, as well as your eyes’ ability to change focus. All of these are important factors in how your eyes see.
Treatment of hyperopia:
Glasses and contact lenses are used by many for the temporary treatment of hyperopia. However, there are a number of vision correction procedures, LASIK for example, that can surgically reduce or eliminate hyperopia.
