Astigmatism is a common refractive error that can be corrected for using glasses or contacts. However, for a long time, people with astigmatism could not wear contacts, which means that not everyone knows that there are options. Here at Mills Eye Care in Mooresville, NC, we enjoy helping people discover the modern world of contact lenses for astigmatism.
What is Astigmatism?
In order to understand why it is more difficult to fit people with astigmatism for contact lenses, we have to consider the condition. Normally, the front of the eye is a smooth, curving surface, like a soccer or baseball. When people are nearsighted or farsighted, the curve is flatter or steeper, but the overall dome-shape is still smooth. Astigmatism is when the curve of the eye is steeper in some places than others, more like a football.
The difficulty of correcting for this error is that it means that people with astigmatism need a different lens power in some parts of their lenses than others. This is easier to do with glasses than with contacts, but that does not mean that there are no contact lens options.
Contact Lenses for People with Astigmatism
There are currently a few options for people who have astigmatism and want to wear contact lenses. Both soft and hard contact lenses are usually an option unless you have an extremely high degree of astigmatism.
- Soft toric lenses use a special technology that prevents rotation of the lens in the eye so that the proper correction stays in the right place.
- Hard, gas permeable (GP) lenses retain their shape and replace the irregularly curved surface of the eye.
- Hybrid lenses offer soft edges for comfort and GP centers for sharper vision.
- Toric GP lenses are available for people with extremely high degrees of astigmatism.
Soft lenses are typically more comfortable, which is why many people stick with them. Depending on your prescription, there are also disposable toric lenses for people who prefer to wear a fresh pair every day and skip the cleaning and storage.
GP lenses tend to provide sharper vision, but they can be more difficult to adjust to wearing. Rigid GP lenses, as well as hybrid lenses, typically require more complex fittings. They are also more expensive upfront, although the fact that you wear them for longer before replacing them may mean that the cost evens out in the end.
