Astigmatism

Astigmatism is a common eye condition that causes blurred or distorted vision at all distances. It occurs when the cornea or the lens of the eye is irregularly shaped. The degree of blurriness varies from person to person with it being mild for some and more severe for others.

There are two types of astigmatism, regular and irregular. Regular is where the curve of the cornea is more pronounced in one direction, either vertically or horizontally. When the uneven curve is across the whole surface, it is irregular. In both types, this irregular curvature prevents light from focusing onto a single point on the retina, resulting in blurred vision.

This condition can be present at birth or can develop later. It can also be caused by an injury, an eye disease or in some cases may be hereditary. Astigmatism symptoms include blurry vision at any distance, difficulty focusing, frequent squinting and difficulty with night vision. Eye strain and headaches are also common especially with prolonged periods of near activity.

A general eye examination can detect astigmatism. In most cases, it can be treated with corrective eye glasses or contact lenses. In more severe situations, the condition may require laser eye surgery to reshape the cornea. Because astigmatism can affect a child’s learning ability, it is essential to have their eyes tested before they start school if they are exhibiting any symptoms.
