Astigmatism is a very common vision condition which is faced by most people. Most people think it is not a serious vision problem. At certain level, astigmatism has no impacts on vision and does not need special treatment. However, when astigmatism results in distorted or blurred vision, eye discomfort and headaches, astigmatism correction is needed.What is astigmatism? Astigmatism is a kind of vision disorders (usually blurred vision) caused by distortions in the curved shape of the front surface of the eye (cornea) and/or the curvature of the lens inside the eye. It can also be caused by years of stress and strain on the eyes. The strain on the eyes can weaken the tiny muscles around the eyes. Problems appear when the eyes need to change shape of cornea or lens. An irregular shape of cornea or lens prevents light from focusing properly on the retina, the light sensitive surface at the back of the eye. As a result, vision becomes blurred at any distance.Astigmatism usually comes together with other vision problems like nearsightedness (myopia) and farsightedness (hyperopia). All of these vision conditions are called refractive errors because they influence how the eyes bend or "refract" light. Now the question is how we can do the astigmatism correction when we have these errors. Below are just a few tips which you can do to heal astigmatism.You can use a pendulum for astigmatism correction. You just lie on the floor and swing the pendulum over your head. Try to follow and focus on direction where the pendulum moves. This exercise can keep your eyes focused on one object. If you keep doing this exercise, your eyes will have better capability in focusing on a certain object.When you feel your eyes are tired, you should take a break. Spend a few minutes to relax your eyes. During the break you can have eye exercise by moving your eyes around. You can also look at the yard or green grass outside. Keep your eyes away from your computer monitor if you work with a computer. Relaxation can release the tense of tiny muscles on your eyes. After the relaxation you will recover your vision.Another treatment for astigmatism is called Orthokeratology (ortho-k). This treatment uses a series of specially designed rigid contact lenses to slowly reshape the curvature of the cornea. What is good about this treatment is that it is painless.Eye surgery is also another option for treating astigmatism. The surgery usually uses laser. The purpose of the surgery is to reshape the cornea by removing a small part of eye tissue.
