Astigmatism of the Eye
Astigmatism is one of the most misunderstood terms in the optical world. While quite a few know that they have astigmatism, lots of people really don't have an understanding of what it implies. In reality, most adults do have some extent of astigmatism. Determined by the severity, it could or could not have an effect on overall eyesight.
What Causes Astigmatism?
Astigmatism happens once the cornea is not wholly spherical in form. This incorrect curvature with the cornea leads to light getting refracted in the eye improperly. When light is not handled by the eye the right way, it can make seeing complicated. For individuals with astigmatism, viewing at any distance may be tough to do.
What are Astigmatism Symptoms?
Individuals with astigmatism usually suffer from headaches, eye strain, blurred vision and eye tiredness. While most people are born with a curvature of the cornea, some will develop it later in life as the result of an injury to the eye or other eye condition. If you detect any adjustment in your vision, it's important to visit the optometrist.
How is Astigmatism Treated?
This problem is easily treatable in most people. Toric lenses will be prescribed to correct astigmatism. These lenses bend the incoming light to account for how the cornea is reacting to light entering the eyes. Laser surgical procedure is another possibility to properly treat astigmatism although many people opt for the significantly less invasive method of contact lenses or eyeglasses.
For anyone with astigmatism who doesn't have farsightedness or nearsightedness, vision correction may not be necessary. For other folks, if the astigmatism is serious or is accompanied by farsightedness or nearsightedness, vision correction is usually needed. An eye exam by a Doctor of Optometry can easily diagnose astigmatism.
