Refractive errors are one of the most common reasons patients schedule eye exams with their eye doctors. A refractive error causes the eye to take on an abnormal shape, preventing light from passing through in a normal manner and resulting in blurry and distorted vision. The most common refractive errors are nearsightedness (myopia) and farsightedness(hyperopia). There is a third type of refractive error that is a bit different called astigmatism and it requires a different kind of treatment from an optometrist. At Modern Eyes Optometry, our eye doctor has years of experience providing Carlsbad residents with treatment for astigmatism.
What Is Astigmatism?
While you can get a general idea of nearsightedness or farsightedness even from a basic vision exam, this is not the case with astigmatism. Astigmatism happens when the cornea or lens of the eye is shaped incorrectly. These parts of the eye are supposed to be roundish, like a basketball, but when astigmatism is present, they are more like a football. Their presence is pretty obvious to an eye doctor when you are undergoing an eye exam, but it may be less obvious to you. Unlike myopia and hyperopia, astigmatism can make it difficult to see both close and distant objects. It is sometimes described as being like seeing the world through a funhouse mirror.
Causes and Signs of Astigmatism
Astigmatism is an irregular curve in the cornea or lens, that causes light to refract improperly, resulting in blurry or distorted vision. It occurs most often alongside nearsightedness or farsightedness. It is unknown exactly why the curvature happens, but whatever the cause is, it does seem to be hereditary. Sometimes, astigmatism develops following surgery or an eye injury. Some signs that astigmatism may be present include:
- Distorted or blurry vision
- Headaches
- Eyestrain or discomfort
- Squinting to see
- Poor night vision
- Double vision
