If you’ve just been told you have astigmatism, and the word alone made you slightly nervous, let me reassure you immediately: it’s one of the most common optical conditions there is, it’s not a disease, and it’s corrected with a standard pair of glasses. That’s it. No surgery, no drops, no drama.
In a perfectly spherical eye, the cornea (the clear front surface) is curved equally in every direction, like a football. In an eye with astigmatism, the curve is slightly steeper in one direction than the other – more like a rugby ball. That uneven curve means light focuses at two different points rather than one, which causes things to look slightly blurred or smudged at certain angles, rather than uniformly sharp or uniformly soft.
Most people have at least a small amount of astigmatism. It’s so common that it would almost be unusual to find an eye with none at all. Low levels often cause no noticeable symptoms and don’t need correcting. Higher levels cause blurring, ghosting around lights (especially at night), and sometimes headaches or eye strain.

The simplest way to think about it Astigmatism isn’t a problem with your eye – it’s a shape. Your cornea is slightly oval rather than perfectly round, so light focuses unevenly. Glasses or contact lenses correct for that shape, and the blur goes away. |
In Glasses
A cylindrical correction (the CYL and AXIS numbers on your prescription) is built into the lens to compensate for the uneven curvature. Your lens type – single vision, varifocal, or occupational – works the same way whether you have astigmatism or not; the correction is just added to whatever else your eyes need. There’s no visual difference in how the glasses look.
In Contact Lenses
Standard contact lenses sit on the eye and rotate freely. That’s fine for a spherical correction, but astigmatism needs the lens to stay oriented at a specific angle. Toric contact lenses are weighted and shaped to hold a stable position on the eye, delivering the cylindrical correction at the right axis. They come in daily, monthly, and multifocal options – astigmatism hasn’t been a barrier to contact lens wear for a long time.
What About Laser Eye Surgery?
Laser correction for astigmatism is well-established and effective. It works by reshaping the cornea to make the curvature more even. It’s not something we perform at a high-street practice, but if it’s something you’re considering, we can advise on suitability and refer you to a specialist.
Children are often diagnosed with astigmatism at their first eye test and it’s almost always straightforward to correct with glasses. If it’s significant enough to affect vision in one eye more than the other, it can contribute to a lazy eye (amblyopia) if left uncorrected – which is exactly why early testing matters. In most cases, the right pair of glasses is all that’s needed.

No - astigmatism is a common variation in the shape of the cornea, not a disease. It's easily corrected with glasses or contact lenses.
Yes - toric contact lenses are specifically designed to correct astigmatism. They come in daily, monthly, and multifocal options.
It can change over time, like any part of your prescription, but it doesn't inevitably get worse. Regular eye tests track any changes.
Yes - it's common in children and usually straightforward to correct with glasses. Early detection matters because uncorrected astigmatism can contribute to lazy eye.
Your glasses will include a cylindrical correction (CYL and AXIS values) but look and feel exactly the same as any other pair. No special frames or unusual lens types are needed.
