Introduction
The primary causes of increased astigmatism are closely related to growth and development, as well as to the cornea and lens. In clinical practice, astigmatism may undergo certain changes during childhood development, but remains relatively stable in adult patients. When a patient experiences a significant change in astigmatism, two potential factors must be considered: first, changes in the cornea; second, changes in the lens.
Currently, many individuals—especially children—experience vision problems such as astigmatism. Common symptoms include decreased or blurred vision, frequent headaches, eye pain, and general ocular discomfort. Therefore, it is essential to promptly identify the underlying causes to enable targeted correction and treatment. So, what causes a sudden increase in astigmatism?
Causes of a Sudden Increase in Astigmatism
The primary causes of increased astigmatism are closely related to growth and development, as well as changes in the cornea and lens. Clinically, astigmatism may fluctuate during childhood development but typically remains relatively stable in adults. When a patient experiences a significant change in astigmatism, two main factors must be considered: first, corneal changes; second, lens-related changes. Corneal alterations greatly influence astigmatism—for instance, patients with keratoconus or new corneal growths (e.g., pterygium or corneal scars) may experience a rapid, marked increase in astigmatism. If corneal pathology is ruled out, lens abnormalities should be investigated—such as cataracts or lens dislocation—which can also elevate astigmatism.
Individuals with astigmatism may use warm water to gently rinse their eyes in daily life, which may help alleviate associated symptoms. First, disinfect the washbasin and fill it with warm water. Once the temperature reaches a comfortable level, submerge your face in the water and slowly open your eyes underwater. Then rotate your eyeballs upward, downward, leftward, and rightward nine times each, followed by nine clockwise and nine counterclockwise rotations. This helps remove debris from the eyes and serves as an adjunctive measure for managing astigmatism.
Patients are advised to protect their eyes diligently—minimizing visual fatigue, avoiding late-night activities, and reducing excessive eye strain. We hope this information proves helpful.
