Hyperopia (Farsightedness) occurs when light rays focus behind the retina, instead of on the retina. The reason for this is that the eye is too short or the cornea is too flat. This is often inherited.
A person with hyperopia is unable to see objects clearly up close like books or newspapers. Many people are not diagnosed with hyperopia until they have a complete eye exam. School screenings do not discover this because they test for vision in the distance.
Treatment includes glasses for near work such as reading, contact lenses or Laser Vision Correction.
