Astigmatism is a common eye condition that occurs when the cornea (the clear outer layer of the eye) or the lens inside the eye has an irregular shape, which causes light to focus unevenly on the retina at the back of the eye. This can lead to blurry or distorted vision at all distances, and may also cause eye strain or headaches.
Astigmatism can be corrected using glasses, contact lenses, or refractive surgery. Glasses or contact lenses work by correcting the uneven curvature of the cornea or lens and allowing light to focus properly on the retina. In some cases, a combination of glasses and contact lenses may be needed to correct astigmatism.
Refractive surgery is another option for correcting astigmatism. There are several types of refractive surgery, including LASIK, PRK, and LASEK, that can reshape the cornea to correct the irregular curvature that causes astigmatism. These procedures are generally safe and effective, but not everyone is a good candidate for surgery and there can be potential risks and complications.
It’s important to see an eye doctor for a comprehensive eye exam if you are experiencing blurry or distorted vision, as astigmatism can often be corrected with the right treatment.
