People who have astigmatism are unable to see light evenly displayed on their retina. This can cause all sorts of issues, and it can also pose a safety risk in situations where people with this condition are driving at night or other instances where your vision is extremely important. Blurry vision is one of the most common signs that you have astigmatism. There are many variables that come into play when trying to figure out whether you can wear contacts with astigmatism.
If you have astigmatism, the good news is that you still will be able to wear contact lenses.
