In the astigmatic eye, the front of the cornea is not equally round; it is slightly oval in shape. As a result, the rays of light that enter the eye are bent unequally and cause distortion of the image, resulting in loss of visual acuity.
Your vision will be sharper with a special lens that has extra power in a specific direction in the lens. This will help to correct for the shape of your eye. As it’s a correction for the shape of the eye, it will help sharpen vision at all distances.
Many people have some degree of astigmatism
How to check if your current glasses have a correction for astigmatism:
- Hold your existing spectacles away from your eyes
- Look at a distant object with a straight surface through one of the lenses
- Rotate the lens. If you can clearly see the distortion of the straight surface as you rotate the lens you are likely to have lenses that correct for astigmatism.
How do you see the fan below? Do all lines appear equally clear? If not, you may have some degree of astigmatism.

Signs that you might have an astigmatism
If your notice that your vision is distorted from both close up reading to looking into the distance, you may have astigmatism. This is not uncommon, with more than 95% of the population having some level of astigmatism after all our bodies are rarely perfectly asymmetrical.
Astigmatism and Contact Lenses
Due to recent advances in technology it is now possible to get contact lenses if you have an astigmatism. Soft contact lenses wrap to the shape of the eye and can be made in a form, whereby the power varies across the lens. Known as toric lenses, they require more specialist fitting than basic soft contact lenses as the angle and power of the correction needs to be matched to your requirements and made so that they will float appropriately in your eye. These are normally daily wear disposable lenses or may be of that type that are replaced after either two weeks or a month.
