What are the reasons for an increase in astigmatism degree?

If a formal optometry examination has been conducted before fitting glasses and it is confirmed to be true astigmatism, there will be no increase in the degree. However, if it is pseudo-astigmatism, there may be an increase in the degree.

Reasons:

1. True astigmatism: True astigmatism generally refers to the optical defect caused by the different refractive rates of the two meridians on the cornea, and patients may experience blurred vision, visual fatigue, and other symptoms. During the optometry examination, doctors will usually determine whether it is true astigmatism based on the patient's actual condition. If astigmatism is indeed found after a formal optometry examination, there will be no increase in the degree.

2. Pseudo-astigmatism: Some people may develop pseudo-astigmatism due to improper long-term use of the eyes or trauma to the eyes, which leads to changes in the shape of the eyeball. In this case, the shape of the patient's eyeball will change compared to a normal person, resulting in an increase in the degree.

Treatment Suggestions:

Patients are advised to promptly visit the hospital and correct the astigmatism by wearing glasses under the guidance of a professional doctor. At the same time, atropine eye drops or other medications can be used as prescribed to alleviate symptoms. If necessary, treatments such as excimer laser surgery can be chosen. In daily life, it is important to use the eyes reasonably, avoid prolonged use of electronic products to prevent worsening of the condition. Additionally, maintaining good living habits, ensuring adequate sleep, and avoiding staying up late are also essential.
