The cornea is the thin transparent covering of the eye. It contributes a large part to the power of the eye. If the cornea is not perfectly round and smooth (like the surface of a lens) it induces astigmatism, and results in vision distortion. Astigmatism can be present in young children or could develop during puberty. In children, astigmatism is a common cause of a “lazy eye”.

Common Symptoms Of Astigmatism

Astigmatism can affect you at any time, so it is necessary to be aware of any signs that you may be suffering from it. The most common symptoms include:

Headaches
Eye strain
Squinting
Distorted or blurred vision at all distances
Difficulty driving at night

When vision begins to appear blurred or fuzzy, either from a known injury or an unknown development over time, a visit to an optician is required. Some vision problems like eye strain can come and go on their own but can still be symptomatic of a more serious disease which would require treatment.

Testing For Astigmatism

Testing for astigmatism is usually part of a comprehensive eye exam. It is important to always be aware of any changes in your vision. Besides astigmatism, it is also useful in detecting any common vision problems. If you notice any changes in your vision, visit your eye care professional for a comprehensive eye examination.
