Myopia is a medical condition that affects vision, causing objects to appear blurry or fuzzy when viewed at a distance. This occurs because light rays from distant objects are focused in front of the retina instead of on it, which prevents clear and sharp images from forming on the retina. Myopia is also known as nearsightedness or short-sightedness, as people with this condition can see clearly at close range but have difficulty seeing far away. It is a common vision problem that usually starts in childhood and may improve over time, although some individuals may require corrective lenses or other treatments to manage their myopia effectively.
