3. Refractive Errors
Refractive errors can impair vision, making it hard to see clearly. Specifically, astigmatism can cause blurred vision at any distance. Recall that astigmatism is caused by an abnormally- shaped cornea that prevents light from focusing adequately on the retina. Additionally, it can also occur when the lens of the eye has an abnormal shape.
In some cases, this refractive error can cause double vision. In fact, astigmatism is a common example of monocular diplopia. If you are experiencing constant headaches, blurry vision at different distances, eye discomfort, and/or double vision you should schedule an appointment with your eye doctor. This is important because astigmatism is easily treatable (eyeglasses, contact lenses) and the best way to diagnose it is through an eye exam.
