H52: Disorders of refraction and accommodation

Disorders of refraction and accommodation, as a group, primarily affect your eye's ability to focus on objects at various distances. Often rooted in the shape and structure of the eye itself, these disorders include conditions such as nearsightedness (myopia), farsightedness (hyperopia), astigmatism, and presbyopia. Symptoms commonly include blurry vision, headache, eye strain and fatigue, particularly during reading or other close-up work. Disease progression varies, but many of these conditions tend to develop gradually over time. Some, like presbyopia, are tied to natural aging processes and typically become noticeable in middle age. These disorders generally don't cause complete vision loss but can affect daily activities and quality of life. It's important to note that regular eye check-ups can help detect these conditions early, which can lead to more effective management and preservation of visual function.
