Hyperopic
Hyperopic
Hyperopic (pronounced: hi-per-oh-pik) is a term used in optometry and ophthalmology to describe a condition where the eye has a shorter than normal eyeball, which causes light to focus behind the retina, rather than directly on it. This results in distant objects being seen clearly, but close ones appear blurred, a condition more commonly known as farsightedness or long-sightedness.
Etymology
The term "hyperopic" is derived from the Greek words "hyper" meaning over or above, and "ops" meaning eye or vision. It was first used in the late 19th century to describe the opposite condition of myopia, or nearsightedness.
Related Terms
- Astigmatism: A common vision condition that causes blurred vision due to the irregular shape of the cornea or the lens inside the eye.
- Presbyopia: A condition associated with aging, in which the eye exhibits a progressively diminished ability to focus on near objects.
- Refractive error: A problem with the eye's ability to accurately focus light on the retina, causing blurred vision.
- Emmetropia: The state of vision where a faraway object at infinity is in sharp focus with the eye lens in a neutral or relaxed state.
Treatment
Treatment for hyperopia can include corrective lenses, such as eyeglasses or contact lenses, and refractive surgery procedures such as LASIK or PRK.
