How Does Astigmatism Worsen?
Astigmatism is a common vision condition that affects millions of people worldwide. It occurs when the cornea or lens of the eye is irregularly shaped, causing light to focus unevenly on the retina. While astigmatism can be corrected with glasses, contact lenses, or refractive surgery, it’s important to understand how it can worsen over time. In this article, we will explore the factors that contribute to the progression of astigmatism and provide tips on how to manage this condition effectively.
Genetic Factors and Family History
One of the primary reasons astigmatism can worsen is due to genetic factors. If you have a family history of astigmatism, you may be more prone to developing or experiencing worsening symptoms. Genetic predisposition can lead to changes in the shape of the cornea or lens, which can cause the astigmatism to become more pronounced.
Environmental Factors
Environmental factors can also play a significant role in the progression of astigmatism. Excessive exposure to ultraviolet (UV) radiation from the sun can lead to changes in the cornea, potentially worsening astigmatism. Additionally, certain eye conditions, such as keratoconus, can cause the cornea to thin and bulge, leading to increased astigmatism.
Age and Lifestyle
As we age, the natural aging process can contribute to the worsening of astigmatism. The lens of the eye becomes less flexible, which can affect its ability to focus light properly. This can lead to changes in the shape of the lens and, consequently, worsening astigmatism. Furthermore, certain lifestyle habits, such as poor nutrition, smoking, and excessive screen time, can exacerbate the condition.
Diagnosis and Management
Early diagnosis and proper management are crucial in preventing the worsening of astigmatism. Regular eye exams can help detect changes in the shape of the cornea or lens, allowing for timely intervention. Treatment options for astigmatism include:
– Glasses: Prescription glasses can help correct the refractive error caused by astigmatism.
– Contact lenses: Soft or rigid gas-permeable contact lenses can provide a more comfortable and precise correction for astigmatism.
– Refractive surgery: Procedures such as LASIK, PRK, or LASEK can permanently correct astigmatism by reshaping the cornea.
Conclusion
Understanding how astigmatism worsens can help individuals take proactive steps to manage their condition effectively. By addressing genetic, environmental, and lifestyle factors, and seeking timely treatment, individuals with astigmatism can maintain good vision and reduce the risk of further complications. Regular eye exams and open communication with an eye care professional are essential in monitoring and managing astigmatism throughout one’s life.
