Astigmatism may be one of the most commonly misunderstood eye conditions. Many believe it’s caused by improper lighting, that it can lead to more serious eye problems, or—something we’ve all likely thought at some point—that it’s called “astigmatism.”
The Basics Of Astigmatism
So let’s clear the air here: the term “astigmatism” comes from the Greek “a” (without) and “stigma” (point or mark). Astigmatism is a type of refractive error in which the eye does not focus light evenly on the retina. Astigmatism is caused when the lens, cornea, or both are not completely smooth, and therefore do not perfectly focus light as it enters your eye, leaving you with blurry vision.
Astigmatism and other refractive errors, like myopia (nearsightedness) and hyperopia (farsightedness), are usually genetic and develop naturally, often from birth or during childhood. Astigmatism is diagnosed through Eye Exam.
What is the main cause of astigmatism?
The symptoms of astigmatism may differ in each person. Some people don’t have any symptoms at all. The symptoms of astigmatism include:
- blurry, distorted, or fuzzy vision at all distances (up close and far away)
- difficulty seeing at night
- eye irritation
- Trouble focusing
- Blurry sight
- Trouble driving at night
Prescription eyeglasses or contact lenses and refractive errors surgery such as LASIK.
Different People Experience Different Levels Of Astigmatism
Astigmatism is actually very common. Astigmatism is a type of refractive error in which the eye does not focus light evenly on the retina. Many of us have some level of astigmatism, but it’s not enough to warrant corrective treatment. Other patients with severe astigmatism may experience other symptoms.
