Hyperopia is present when light rays focus behind the retina, instead of on the retina. The reason for this is that the cornea is too flat or the eyeball is too short. This is often inherited. It is often called "farsightedness" by laypersons, but this is an inaccurate term. Patients with this disorder often do have blurred vision at near, but many also have blurred vision at distance as well, especially in more severe cases.

Many people are not diagnosed with hyperopia until they have a complete eye exam. School screenings often do not detect this if they test for distance vision only.

Treatment includes contact lenses or glasses to correct the disorder.
