Astigmatism is a condition that causes blurry or distorted vision in the eyes. It occurs due to a refractive error, forcing light to be focused unevenly on the retina. While the cause of astigmatism is still unclear, experts believe that it may be due to genetic factors. The mechanism of the condition involves abnormalities in the lens of the eye or irregular curvature of the cornea. The diagnosis of astigmatism can be achieved through patient history, the examination of the eye, and an eye exam. Astigmatism was first identified by Thomas Young in 1801.

There are three options for the treatment of astigmatism, which includes spectacles (glasses), contact lenses, or surgery. Spectacles are the easiest and simplest way to correct the condition. However, contact lenses have the advantage of providing a wider field of vision. Surgery can also be performed to permanently change the shape of the eye. This condition is observed to affect individuals of all ages. In Asia and Europe, as many as 30 to 60 percent of adults are affected.

Astigmatism Symptoms #1: Blurry Vision

Blurry vision occurs when the image one sees is no longer sharp. It is a common ocular symptom that can be caused by presbyopia, use of atropine, cataracts, diabetic retinopathy, glaucoma, macular degeneration, retinal detachment, optic neuritis, and more. In astigmatism, the blurry or distorted vision occurs at all distances.
