What is astigmatism?
Astigmatism is one of the common vision problems caused by the wrong shape of the cornea. According to experts, the cause of the condition is still unknown. However, genetics play a higher role in the cause.
It is often present at birth but can develop later in life. It can also occur as a result of an eye injury or after eye surgery. Astigmatism often occurs with nearsightedness or farsightedness.
Symptoms of astigmatism
Although symptoms may vary from individual to individual, some patients may have no symptoms at all. The main symptoms of astigmatism include:
blurred, distorted, or foggy vision at all distances (near and far)
night vision problems
eye strain
squinting
eye irritation
headaches
Who is at greater risk?
Astigmatism, a vision problem, can occur in children and adults. The likelihood of developing this condition may be higher in the following categories:
a family history of astigmatism or other eye diseases such as keratoconus (corneal degeneration)
scarring or thinning of your cornea
excessive myopia, causing blurred distance vision
excessive farsightedness that creates blurry close-up vision
a history of certain types of eye surgery, such as cataract surgery (surgical removal of the cloudy lens)
