Astigmatism can cause night blindness which is the most dangerous symptom. After the sun has set, astigmatism patients can hardly see the road and motorist. So they are not supposed to drive in the darkness. Actually, people with astigmatism suffer a lot besides night blindness. When people have astigmatism, their cornea or lenses tends to refract light in two or more places, which causes blurred vision or field. This will lead to severe headache. Sensitivity to light can occur to people with astigmatism. For them, taking measures to protect the eyes from light is necessary. There are also cases in which the patients suffer from dizziness that is related to astigmatism. If the patients focus on the objects close to or far away from them, they will feel eyestrain. This can be solved by just closing eyes to have a rest. However, astigmatism can be cured. You should consult your doctor and choose the treatment that best suits you.
