MYOPSIS Meaning and
Definition
-
Myopia, also known as "nearsightedness," is a common eye condition characterized by the inability to see distant objects clearly. It is a refractive error in which the eyeball is slightly elongated or the cornea is excessively curved, causing light to focus in front of rather than directly on the retina. People with myopia often have good near vision but experience blurry vision when attempting to see objects at a distance.
The onset of myopia is typically during childhood or adolescence, although it can develop in adulthood as well. The condition is thought to be influenced by both genetic and environmental factors, with excessive near work, limited outdoor activities, and a family history of myopia being significant risk factors. Aside from blurry distance vision, common signs and symptoms of myopia include squinting, headaches, eye strain, and difficulty seeing while driving or watching movies.
Myopia can be diagnosed through a comprehensive eye examination, where an optometrist or ophthalmologist measures the refractive error using a phoropter or autorefractor. The correction of myopia can be achieved with eyeglasses, contact lenses, or refractive surgery such as LASIK. Some individuals with myopia may experience progressive worsening of the condition over time, leading to higher refractive corrections.
Regular eye examinations and appropriate corrective measures are essential to manage myopia and ensure optimal visual function. Additionally, lifestyle modifications such as spending time outdoors and taking regular breaks from near work can help slow down the progression of myopia.

Etymology of MYOPSIS
The word "myopsis" is derived from Greek roots. It comes from the combination of the Greek word "myo" (μύω), meaning "to close" or "to shut", and "opsis" (ὄψις), meaning "sight" or "vision". Therefore, "myopsis" can be understood as a condition or disorder where one's vision is partially or completely closed or shut, usually referring to nearsightedness or short-sightedness.
