Astigmatism is a common eye problem that causes blurred vision, headaches, and eye strain.
If you have an astigmatism, the clear outer covering of your eye (cornea, or lens) is more oval-shaped than round. Your cornea directs light rays into your eye. Then it focuses the light rays on the retina at the back of the eye. If the surface of the cornea has an oval shape, light rays may not focus on the retina as they should.
Eyeglasses, contact lenses, or surgery can correct this problem. Contact lenses for astigmatism are called toric lenses. Some may need to be custom-made. They may cost more than ordinary contact lenses.
Astigmatism is an abnormal curvature of the clear outer covering of the eye (cornea), causing blurry vision.
The cornea directs light rays into the eye and focuses them on the light-sensitive retina at the back of the eye. If the surface of the cornea is irregular, light rays may not focus properly on the back of the eye.
Vision problems caused by astigmatism can be treated with eyeglasses, contact lenses, or surgery.
