Miyop, or myopia, is a common vision condition where distant objects appear blurry while close objects can be seen clearly. This occurs when the eyeball is too long or the cornea has too much curvature, causing light rays to focus in front of the retina instead of directly on it. Myopia often develops in childhood and can worsen during the teenage years. It is typically diagnosed through a comprehensive eye exam. Treatment options include corrective lenses, such as glasses or contact lenses, and in some cases, refractive surgery like LASIK may be considered for adults.
