An astigmatism is an eye condition that is usually corrected using contact lenses, eyeglasses or surgery. An astigmatism is actually an irregular curvature of the cornea and this causes a refractive error in the eye. Almost everyone has some sort of this eye condition and for those that have significant curvature treatment is recommended.
A normal eye is shaped like a sphere but someone with this eye condition will have an eye that is shaped like a football or even in a shape like the back of a spoon. Therefore when the light goes into your eye it will refract in several different direction so that only a section of what you are looking at is in focus. With an astigmatism you may have blurry sight at all distances.
Most times this eye condition is hereditary and your eye may be like that when you are born. However sometimes this can be caused by too much close work, incorrect posture and pressure on the cornea due to the eyelids. Some symptoms include fatigue, eyestrain, headaches and blurred vision. An exam is needed to correctly diagnose an astigmatism.
Most times this is corrected by using contact lenses or eyeglasses. If you want contact lenses then you will need to have toric lenses specifically prescribed as these have a greater ability to bend light in the needed direction then the more usual contact lenses. You can also have refractive surgery as this changes the shape of your cornea. The type of surgery will depend on your type of astigmatism.
May times you do not need to have surgery. You should talk with your eye doctor about the treatments that will work for your type of astigmatism. They will be able to recommend the best treatments and you will be back to seeing normally. His eye condition is very treatable.
