hyperopia etymology

Etymology:

Hyperopia comes from the Greek words:

  • "hyper" = over, excessive
  • "opia" = eye

Meaning:

Hyperopia, also known as farsightedness, is a condition in which a person has difficulty seeing objects that are close to them, while they can see objects that are far away more clearly.

Origin:

The term "hyperopia" was first coined by François Donders, a Dutch ophthalmologist, in 1864. He used it to describe the opposite of myopia (nearsightedness). Hyperopia is caused by the eyeball being too short or the cornea (the transparent outer layer of the eye) being too flat. As a result, light rays entering the eye focus behind the retina (the light-sensitive layer at the back of the eye), causing distant objects to appear clear while near objects appear blurry.
