Blurred images at both distance and near.

What is Astigmatism?

Irregular curvature of the eye resulting in blurred vision.


Astigmatism is caused by irregularities in the curvature of the parts of the eye responsible for focusing light rays
(the cornea and the lens). An even curve (a round eye) results in even distribution of the light rays making up an image,
which will be clear. If the curvature of the eye is uneven (rugby ball shaped), light rays will be unevenly distributed,
causing blurred images at distance and at near.


The opticians’ prescriptions will show two numbers, called ‘Sphere’ and ‘Cylinder’. The larger the cylinder is, the
more astigmatism there is and the greater the blur.
