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 the ability to read and concentrate. This underlines the importance of regular eye tests with the optician for you and especially for young children.
Treatment
The condition is generally mild and does not require treatment beyond the 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.
