HYPERMETROPY Meaning and
Definition
-
Hypermetropy, also known as hyperopia or farsightedness, is a refractive error of the eye in which distant objects are seen more clearly than near objects. It is a common vision condition caused by an abnormal shape of the eye or a fault in the focusing mechanism. The term "hypermetropy" is derived from the Greek words "hyper," meaning excessive, and "metros," meaning measure.
In individuals with hypermetropy, light rays entering the eye are not accurately focused on the retina, the light-sensitive layer at the back of the eye. This occurs when the eyeball is too short or the cornea, the clear front surface of the eye, has insufficient curvature. As a result, light rays converge behind the retina instead of directly onto it, leading to blurred vision when looking at close objects.
Hypermetropy can be classified into three types: simple hypermetropy, pathological hypermetropy, and functional (or acquired) hypermetropy. Simple hypermetropy is the most common form, typically inherited, and results from a shorter-than-normal eyeball. Pathological hypermetropy is usually linked to underlying eye diseases or conditions, such as cataracts or retinal detachment. Functional hypermetropy occurs due to temporary factors, such as exhaustion or drug use.
The condition can be corrected through the use of corrective lenses, such as glasses or contact lenses, which help to focus light rays onto the retina. Additionally, some individuals with mild hypermetropy may not require corrective measures, as their eyes can compensate for the refractive error. Regular eye examinations are important to detect and manage hypermetropy, as well as to rule out any associated eye conditions.

Etymology of HYPERMETROPY
The word "hypermetropy" is derived from two Greek roots: "hyper" meaning "beyond" or "excessive", and "metron" meaning "measure" or "distance". In the context of vision, "metropy" refers to the ability of the eyes to focus on objects at a specific distance. Therefore, "hypermetropy" describes a condition where the eyes have a refractive error that causes light to focus behind the retina when viewing objects at a normal distance, resulting in blurred vision. The term is commonly known as "hyperopia" or "farsightedness" in English.
