Myopia, commonly known as nearsightedness, is a refractive error of the eye that causes distant objects to appear blurry while close objects remain clear.

•  It occurs when the eyeball is elongated or the cornea is excessively curved, causing light to focus in front of the retina instead of directly on it.

Myopia typically develops during childhood or adolescence and may progress over time. Factors such as genetics, environmental factors, and excessive near work or screen time are associated with its development. Myopia can be corrected with eyeglasses, contact lenses, or refractive surgery. Regular eye exams are important to monitor myopia progression and ensure appropriate vision correction.
