Patients suffering from astigmatism do not have evenly round corneas, rather corneas with various curvatures (bumps and dips) in different directions.
There is a difference between genetic regular and irregular astigmatism. The latter can also be caused by eye disorders, such as inflammation of the cornea or cataracts.

The malformed cornea leads to irregularities in the refractive power of the eye, as a result of which points become lines when looking at objects.
Images and objects look more or less warped to the viewer. The world seems blurred.
