Astigmatism typically requires treatment to correct the blurred or distorted vision it causes. While mild astigmatism may not require immediate correction, moderate to severe astigmatism can significantly affect daily life and can lead to headaches, eye strain, and difficulty seeing clearly.
The most common treatments for astigmatism include eyeglasses, contact lenses, and refractive surgery. Each of these treatments works by adjusting the way that light enters the eye, to correct the irregular shape of the cornea or lens.
Eyeglasses
Eyeglasses are the most common treatment for astigmatism. Prescription glasses are made with lenses that have a special shape to help focus light on the retina, and are available in both single vision and multifocal lenses. People with mild astigmatism may only need glasses for certain activities, such as reading or driving, while others with more severe astigmatism may need to wear glasses all the time.
Contact Lenses
Contact lenses are another common treatment for astigmatism. Toric contact lenses are specially designed to fit the shape of the eye and correct the irregular curve of the cornea. They come in both soft and rigid gas-permeable materials and can be worn daily or for extended periods of time.
Refractive Surgery
Refractive surgery is a more permanent solution for astigmatism. These procedures reshape the cornea to correct the irregular curvature and improve vision. The most common types of refractive surgery for astigmatism include LASIK, PRK, and LASEK. These surgeries are generally safe and effective, and can provide long-lasting vision correction. However, they are not suitable for everyone, and should be carefully considered with an eye doctor.
Prevention of Astigmatism
While it may not always be possible to prevent astigmatism, there are some steps you can take to reduce your risk or minimize the severity of the condition. These include:
Get regular eye exams: Regular eye exams can help detect and treat astigmatism early, before it becomes more severe.
Protect your eyes: Wear protective eyewear when playing sports or doing activities that could lead to eye injuries.
Practice good eye hygiene: Wash your hands before touching your eyes, and avoid rubbing your eyes.
Follow a healthy lifestyle: Eating a healthy diet, exercising regularly, and avoiding smoking can all help maintain good eye health.
Conclusion
Astigmatism is a common eye condition that affects millions of people worldwide. It is a refractive error that causes blurred or distorted vision due to an irregular shape of the cornea or lens of the eye. While mild astigmatism may not require immediate correction, moderate to severe astigmatism can significantly affect daily life and can lead to headaches, eye strain, and difficulty seeing clearly. Treatments for astigmatism include eyeglasses, contact lenses, and refractive surgery. By taking steps to maintain good eye health, you can help reduce your risk of developing astigmatism and other vision problems.
