Astigmatism, a common refractive error, arises from an irregularly shaped cornea or lens, leading to blurred vision at various distances. The progression of this condition, characterized by an increasing degree of visual distortion, is influenced by a complex interplay of factors. These factors can range from genetic predisposition and natural aging processes to specific environmental influences and underlying medical conditions.
Understanding the etiology of increased astigmatism is crucial for effective vision management. Identifying modifiable factors allows for proactive strategies to mitigate potential deterioration. Furthermore, a comprehensive understanding facilitates more accurate diagnoses, enabling timely interventions such as corrective lenses, vision therapy, or surgical procedures. Historically, research has focused on congenital causes; however, recent investigations highlight the significance of acquired factors in the long-term trajectory of the refractive error.
