Blurry vision is not the only symptom of astigmatism, people with this condition can also experience eyestrain or discomfort, headaches, difficulty seeing at night. Some people are born with astigmatism and may not know they have it until they are screened for it during an eye test. People who discover they have astigmatism can still live relatively hassle-free lives. The most common way to treat the symptoms for astigmatism are glasses, contact lenses, and refractive surgery.
Refractive errors are the most common of the ocular problems among all age groups. According to studies and reports from the World Health Organization, they are also the first cause of visual impairments and the second cause of visual loss worldwide, as 43% of global visual impairments are due to refractive errors. Uncorrected refractive errors were the cause of blindness in 6.8 million people in 2010 worldwide. In the United States astigmatism occurs in 1 out of 3 people.
