Symptoms
By Mayo Clinic staffSigns and symptoms of astigmatism may include:
- Distortion in portions of your visual field
- Blurred vision
- Eyestrain
- Headaches
When to see a doctor
If your quality of vision detracts from your enjoyment of activities or interferes with your ability to perform everyday tasks, see an eye doctor. An eye doctor can determine the degree of your astigmatism and advise you of your options to correct your vision.
If you're a healthy adult older than 40, have your eyes examined about every two to four years until age 65. After age 65, have them checked every one to two years for signs of eye disease or problems. If you have eye problems, such as astigmatism, you may need to have your eyes checked more frequently. If you're at risk of certain eye diseases, such as glaucoma, or you have diabetes, check with your doctor to see how often you need to have your eyes examined.
