Short-sightedness, also known as myopia, is a common vision problem in which people can see nearby objects clearly, but distant objects appear blurry. This occurs when the eye is longer than normal, or the cornea is too curved, causing light to focus in front of the retina instead of directly on it.

Short-sightedness can be caused by a combination of genetic and environmental factors, such as spending too much time focusing on nearby objects, such as reading or using digital devices, or not spending enough time outdoors.

Short-sightedness can be corrected with glasses or contact lenses that are designed to adjust the way that light enters the eye. There are also surgical options available, such as LASIK or PRK, which reshape the cornea to improve vision.

It is important to have regular eye exams to detect and manage short-sightedness, as well as other vision problems that can affect eye health and quality of life. Additionally, taking breaks from digital screens, spending time outdoors, and maintaining good overall health habits can help reduce the risk of developing or worsening short-sightedness.
