Ask Dr Miriam.

Byline: MIRIAM STOPPARD

Qsm My optician has said I have astigmatism and will require special glasses.

Can you tell me what it is? A It's an uneven curvature of the cornea at the front of the eye that distorts vision, resulting in blurring of small print.

f e You'll probably have noticed difficulty in reading and sometimes trouble with both near and distant vision.

Your vision can usually be corrected by glasses with specially curved lenses to compensate for the uneven cornea and sometimes rigid contact lenses are also effective because they smooth out the cornea's surface.

There's also surgery for refractive errors, such as lasik (when the cornea is re-shaped by a laser).
