Why Astigmatism Gets Worse
Astigmatism, a common refractive error affecting the shape of the cornea or lens, can cause blurred vision at various distances. While many people assume that astigmatism is a static condition, it is important to understand why astigmatism gets worse over time. This article delves into the reasons behind the progression of astigmatism and offers insights into managing and treating this eye condition.
1. Natural Aging Process
One of the primary reasons why astigmatism gets worse is the natural aging process. As we grow older, the tissues in our eyes, including the cornea and lens, can change shape. This can lead to a worsening of astigmatism, as the irregular curvature of the cornea or lens becomes more pronounced. Additionally, the aging process can also affect the elasticity of the eye’s structures, further contributing to the progression of astigmatism.
2. Eye Strain and Overuse
Eye strain and overuse, particularly in today’s digital age, can exacerbate astigmatism. Staring at screens for extended periods can cause the eyes to work harder, leading to muscle fatigue and an increased risk of astigmatism. Activities such as reading, writing, and using electronic devices can strain the eyes and contribute to the worsening of astigmatism.
3. Poor Eye Health Habits
Poor eye health habits, such as not wearing corrective lenses as prescribed, can lead to a worsening of astigmatism. People with astigmatism who do not wear glasses or contact lenses as recommended by their eye care professionals may experience blurred vision and eye strain, which can contribute to the progression of astigmatism. Moreover, failing to follow proper eye care routines, such as maintaining good hygiene and regularly visiting an eye doctor, can also exacerbate the condition.
4. Underlying Health Conditions
Certain underlying health conditions can contribute to the worsening of astigmatism. For example, diabetes, which can cause changes in the eyes’ structures, can lead to a more significant astigmatism. Other conditions, such as keratoconus, a progressive condition that causes the cornea to thin and bulge, can also result in a worsening of astigmatism.
5. Inadequate Correction
If astigmatism is not properly corrected, it can lead to a worsening of the condition. Inadequate correction can result from outdated prescriptions, improper fitting of corrective lenses, or failure to update prescriptions as the astigmatism worsens. It is essential for individuals with astigmatism to regularly visit an eye care professional to ensure their corrective lenses are up-to-date and properly fitted.
Conclusion
Understanding why astigmatism gets worse is crucial for managing and treating this eye condition effectively. By addressing the underlying causes, such as the natural aging process, eye strain, poor eye health habits, underlying health conditions, and inadequate correction, individuals with astigmatism can take steps to slow down the progression of their condition and maintain clear vision. Regular visits to an eye care professional and adopting healthy eye habits are key to managing astigmatism and ensuring optimal eye health.
