Etymology. The term hyperopia comes from Greek ὑπέρ hyper "over" and ὤψ ōps "sight" (GEN ὠπός ōpos).

What is the main cause of hyperopia?

Most commonly, farsightedness is caused by a cornea (the clear layer at the front of the eye) that isn't curved enough or by an eyeball that's too short. These two problems prevent light from focusing directly on the retina. Instead, light focuses behind the retina, which makes close-up objects look blurry.

Is hyperopia a genetic disorder?

In many farsighted people, this vision problem is not part of a larger genetic syndrome. However, farsightedness (especially high hyperopia) can be a feature of other disorders with a genetic cause.
