Astigmatism Against the Rule

Astigmatism is a vision condition that affects the way light is focused on your retina, the light-sensitive surface in the back of your eye. It is a common and treatable eye condition that causes blurred or distorted vision. Astigmatism is an eye condition caused by an irregularly shaped cornea. Astigmatism “against the rule” means that the steepest and flattest parts of the eye are in an unusual pattern.

Astigmatism “against the rule” is usually caused by an irregularity in the surface of the cornea and the lens. An irregularly shaped eye interferes with the normal focusing of light onto the retina, so that it produces a distorted image. This type of astigmatism doesn’t necessarily mean that the eye is abnormally shaped, but rather that the focusing of light is not as it should be.

The symptoms of astigmatism “against the rule” include blurry vision, double vision and ghosting where images appear double or distorted. Depending on the severity of the condition, a person may need glasses, contacts or surgery to correct the vision. Astigmatism “against the rule” can be treated with eyeglasses, contact lenses or refractive surgery.

Eyeglasses are the simplest treatment for astigmatism “against the rule” and can provide clear vision. The lenses in glasses correct the irregular focusing of light, allowing images to be seen clearly. Contact lenses are also effective for treating astigmatism “against the rule,” and can provide better vision than eyeglasses in some cases. For people who cannot or don’t want to wear glasses or contacts, refractive surgery is an option. This procedure reshapes the surface of the cornea to correct the irregular focusing of light.

Astigmatism “against the rule” is a common eye condition that can affect the way people see. It can affect one or both eyes and can be corrected with glasses, contacts or surgery. If you are experiencing blurry vision or other problems with your eyes, it is important to see an eye doctor to determine the cause and discuss treatment options.
