Astigmatism is a very common but usually minor condition caused by an irregular-shaped cornea or lens.
The symptoms can be blurred or distorted vision. If left untreated, it can also lead to headaches and eye strain.
Astigmatism can go undiagnosed for years. And it can affect ability to read and concentrate. This underlines the importance of regular eye tests with the optician for you and and especially for young children.
The condition is generally mild and so does not require treatment beyond prescription of corrective glasses. “Toric” contact lenses suitable for astigmatism are also available nowadays for people who prefer contact lenses to spectacles.
In some – more severe – cases, corrective laser surgery may be appropriate.
