【shortsightedness】Summary:
Shortsightedness, also known as myopia, is a common vision condition in which a person can see nearby objects clearly but has difficulty seeing objects that are far away. This condition occurs when the eyeball is too long or the cornea is too curved, causing light to focus in front of the retina instead of directly on it. Shortsightedness typically develops during childhood and may worsen during adolescence before stabilizing in adulthood.
While the exact cause of shortsightedness is not fully understood, genetic factors and environmental influences, such as prolonged near work (e.g., reading, using digital devices), are believed to play a role. The condition can be corrected with glasses, contact lenses, or refractive surgery like LASIK. Regular eye exams are important for early detection and management.
