Longsighted: meaning, definitions and examples
👀
longsighted
[ ˈlɔŋˌsaɪtɪd ]
vision issue
Longsightedness, also known as hyperopia, is a common vision condition where distant objects can be seen clearly, but nearby objects may be blurry. This occurs when the eyeball is too short or the cornea is too flat, which prevents light rays from focusing directly on the retina. People with longsightedness may experience eye strain or difficulty reading or performing close-up tasks, especially as they get older. Corrective lenses or surgery can help improve vision for those affected.

Etymology
The term 'longsighted' derives from the combination of 'long' and 'sighted.' The word 'long' originates from the Old English 'lang' and has Proto-Germanic roots, meaning 'having a great distance from one end to another.' 'Sighted,' on the other hand, comes from the word 'sight,' which has its origins in Old English 'siht,' denoting the ability to see. 'Sight' itself derives from Proto-Germanic as well, emphasizing the visual capabilities of a person. The medical use of the term began to be documented in the late 19th century, aligning with advancements in optics and a greater understanding of visual impairments. Hyperopia, the scientific term for longsightedness, was established as optometry evolved in conjunction with ophthalmology, leading to clearer definitions and treatment methodologies.
