Nearsightedness, a common vision problem, is spelled using the IPA phonetic transcription as: /ˌnɪəˈsaɪtɪdnəs/. The first syllable is pronounced as "neer," rhyming with "peer," followed by "sight," pronounced as "saɪt," and ending with "edness," pronounced as "ɪdnəs." This condition, also known as myopia, causes distant objects to appear blurry. Corrective lenses or surgery are common treatments for those with nearsightedness. The spelling of the word can be tricky, but using the correct pronunciation can help understand and remember it more easily.
Nearsightedness, also known as myopia, is a refractive error of the eye where objects that are close appear clear, while objects at a distance appear blurry or out of focus. It is a common vision condition that affects many individuals worldwide. In nearsightedness, the shape of the eye causes light rays to focus in front of the retina instead of directly on it.
The main characteristic of nearsightedness is the ability to see objects up close clearly, such as reading a book or using a smartphone, while experiencing difficulty in focusing on objects in the distance, such as road signs or a whiteboard in a classroom. This occurs due to the eyeball being longer than normal or the cornea having excessive curvature, leading to the light rays converging in front of the retina rather than directly on it.
Individuals with nearsightedness may experience symptoms like eye strain, headaches, squinting, or the need to sit closer to objects to see them clearly. This refractive error can be diagnosed through a comprehensive eye examination conducted by an optometrist or ophthalmologist, and it can be corrected through the use of prescription eyeglasses, contact lenses, or refractive surgery.
Regular eye check-ups are essential to monitor the progression of nearsightedness and ensure proper corrective measures are implemented. Besides, practicing good eye habits, such as taking breaks from near work and maintaining proper lighting conditions, can help alleviate symptoms and slow down its progression.

The word "nearsightedness" is derived from the combination of "near", meaning close, and "sightedness", which refers to the ability to see. It refers to a visual condition where individuals can see nearby objects clearly, but their ability to see distant objects is impaired or blurry.
