Under normal circumstances, the human eye is shaped like a globe. This allows light to reflect off the lens and create clear images. With astigmatism, the eye is shaped like a football. That causes the light to be reflected off the lens in ways that create blurry and out of focus images.
How Is It Diagnosed?
Optometrists use regular eye examinations to detect astigmatism at its earliest stages. It is an extremely common issue that can be detected using lights reflecting off the eye lens. Astigmatism is one of the conditions the eye doctor is checking for when he shines the light in your eyes. During the eye exam, the eye doctor will take a look at your eyeball to see if there are any changes in its shape.
Prescription glasses or contact lenses can be used to alter the way the lens reflects light, which will correct the problems caused by astigmatism. As the person gets older, their eyewear prescription may have to be altered to keep up with the changes in the eyes. This is why it is important that people have their eyes examined on an annual basis. As the eye changes, your doctor can change your prescription to keep your vision clear.
Is Surgery Used?
In some extreme cases, a procedure called refractive surgery is used to alter the shape of the cornea and correct the problem. Laser eye treatments are the most popular forms of refractive surgery. Each surgical procedure is diagnosed and executed on an individual basis as no two eyes are ever exactly the same.
When you keep your annual eye appointments, your eye doctor can easily diagnose astigmatism and recommend several treatment options. The cause of astigmatism is not quite understood, but there are plenty of effective ways available to make sure that you can always see clearly.
