Definition
vision condition
Farsightedness, or hyperopia, is a common vision condition where distant objects can be seen clearly, but nearby objects may be blurry. It occurs when the eyeball is too short or the cornea is not curved enough, causing light entering the eye to focus behind the retina. This condition can lead to eye strain, headaches, and difficulty with tasks that require near vision.
Synonyms
hyperopia, long-sightedness.
Examples of usage

The term 'farsightedness' comes from the combination of the words 'far' and 'sight'. The root 'far' indicates the ability to see objects at a distance clearly, while 'sight' relates to vision. The condition itself has been documented since ancient times, but the medical terminology developed over centuries, particularly with advancements in the understanding of optics and eye health. In the 19th century, the term 'hyperopia' became commonly used in medical literature to describe this refractive error. The nature of farsightedness is linked to the structure of the eyeball and how it refracts light, which has been extensively studied through both scientific inquiry and clinical practice.
