Astigmatism

Astigmatism is where the cornea is shaped like a rugby ball instead of its normal shape of a football. When someone suffers with astigmatism the cornea has two different curves, one steeper and the other flatter.

Astigmatism affects both distance and near vision and can cause headaches and eyestrain. This blurred vision is due to the light and image focuses on more than one point in the eye. The visual problems can be corrected using spectacles, contact lenses and some forms of refractive surgery.
