Definition: Myopia, commonly known as nearsightedness, is a refractive error of the eye where distant objects appear blurred while close objects can be seen clearly.

Causes: The primary causes of myopia include genetic factors, environmental factors such as prolonged close-up work or reading, and anatomical changes in the eye’s structure.

Treatment: Myopia can be corrected using eyeglasses, contact lenses, or refractive surgery like LASIK. Orthokeratology and atropine eye drops are other treatment options aimed at slowing its progression.
