The most common symptom of astigmatism is blurred vision. Some people describe it as double vision but in only one eye. Some people with astigmatism develop eyestrain, squinting and headaches from working to focus on near or distant objects. People are born with astigmatism, but it may not be noticed until a child begins to attend school or learns to read.
