Nearsightedness, also known as myopia, is a common vision condition where close objects are seen clearly, but distant objects appear blurred. It occurs when the shape of the cornea or lens is not perfect, causing light to focus in front of the retina instead of directly on it. While nearsightedness is often associated with genetics and typically develops in children and teenagers, it is possible for adults to suddenly develop nearsightedness. In this article, we will delve into the factors that contribute to the sudden development of nearsightedness, its symptoms, and the available treatment options.
