Could You Have An Eye Astigmatism?

How Astigmatism Causes Blurred Vision

The first layer of the eye is the cornea, which is a transparent, dome-shaped layer. From there, the light passes through the pupil and the lens. The cornea and the lens are two parts of the eye that help focus the light. Corneal astigmatism occurs when the cornea, the transparent, dome-shaped layer of the eye, is misshapen. Lenticular astigmatism occurs when the lens’ shape is distorted. Both of these types result in blurred vision at all distances. Blurred vision is the result of a refractive error, since either the cornea or the lens is not allowing light to focus properly at the back of the eye, and may do so in more than one place.

Though blurry vision is the most common symptom of astigmatism, it does not always mean blurry vision is the result of this condition, since other refractive errors, such as nearsightedness or farsightedness, also cause it. This is why diagnosing astigmatism, discussed next, is so important.
