Q: Precisely what is astigmatism and just how can it be corrected?

A: Someone with astigmatism comes with a unevenly curved cornea – the clear covering from the front of the eye – or unevenly curved lens inside their eye, shaped more like a rugby ball than a football.

Imagine a rugby ball sliced by two along its longest part. The cut surface is definitely an oval shape, and also you position the cut surface flat using a table. Imagine you are looking at it from its pointed end – the sides curve up steeply. Imagine you are searching for it from halfway between two pointed ends – the sides curve a smaller amount steeply. Now you have an exaggerated version of the model of the astigmatic cornea.

It is corrected by spectacles having a cylinder shape built in the lenses for a certain angle. Contacts may correct astigmatism – mild astigmatism is usually corrected by an ordinary gas-permeable lens. People who prefer a soft lens or have higher levels of astigmatism can use specially designed 'toric' soft lenses.
