What is Astigmatism?
Astigmatism is a common eye condition that causes blurry or distorted vision. It occurs when the cornea (the clear front surface of the eye) or the lens inside the eye is irregularly shaped, preventing light from focusing properly on the retina. This can cause objects to appear distorted or blurry, and can also cause headaches and eye strain.
How Does Astigmatism Look?
Astigmatism can cause a variety of visual symptoms, including:
Blurred Vision
People with astigmatism may experience blurred vision, particularly when looking at objects that are far away. This can make it difficult to read road signs or see details in the distance.
Distorted Vision
Astigmatism can also cause objects to appear distorted or misshapen. This can make it difficult to recognize faces or read text.
Headaches and Eye Strain
Because the eyes are constantly adjusting to compensate for the irregular shape of the cornea or lens, people with astigmatism may experience headaches or eye strain.
How Can Astigmatism Be Corrected?
Fortunately, astigmatism can be corrected with the use of corrective lenses. These lenses can be prescribed by an optometrist or ophthalmologist and can be worn as glasses or contact lenses.
Glasses
Glasses are the most common way to correct astigmatism. They work by bending the light that enters the eye, compensating for the irregular shape of the cornea or lens. Glasses can be made with a variety of lenses, including single vision, bifocal, or progressive lenses.
Contact Lenses
Contact lenses can also be used to correct astigmatism. These lenses are specially designed to fit the shape of the eye and can provide clearer vision than glasses for some people.
Laser Eye Surgery
For people who want a more permanent solution to their astigmatism, laser eye surgery may be an option. This procedure reshapes the cornea using a laser, correcting the irregular shape and allowing light to focus properly on the retina. However, not everyone is a candidate for laser eye surgery and it is important to consult with an ophthalmologist before considering this option.
Conclusion
Astigmatism is a common eye condition that can cause a variety of visual symptoms. Fortunately, it can be corrected with the use of corrective lenses or laser eye surgery. If you are experiencing blurry or distorted vision, it is important to consult with an optometrist or ophthalmologist to determine the best course of treatment for your individual needs.
