Myopia, commonly known as short-sightedness, is a vision condition where distant objects appear blurry while close objects can be seen clearly. It occurs when the eyeball is too long. As a result, light entering the eye is focused in front of the retina instead of directly on it. This causes the image to be out of focus when it reaches the retina, leading to difficulty in seeing distant objects clearly.
Myopia is a common vision problem and can develop in childhood or adolescence. Genetics often play a significant role in the development of myopia, but environmental factors like excessive near work (such as reading or using electronic devices for extended periods), limited time spent outdoors, and other lifestyle factors can also contribute to its progression.
Having myopia increases the risk of certain eye conditions, including retinal detachment and macular degeneration. Regular examinations are important to detect any eye disease associated with myopia and to ensure vision is effectively corrected.
