Astigmatism Hard to Correct?

A lot of people where glasses. In fact, it is estimated that 30-50% of people in the United States and Canada wear glasses or eye contacts. There are many reasons for why people wear glasses, though the most common is astigmatism.

Astigmatism is an eye condition that is not understood by some people, and it’s really no wonder, considering the fact that it isn’t as often discussed as it really should be. That’s why we’ll talk about astigmatism and we’ll answer the question is astigmatism hard to correct?

What is Astigmatism?

It’s quite possible that you or someone you know has an astigmatism. It’s an extremely common problem that practically every person experiences to one degree or another. To properly understand what an astigmatism is, it’s important to first discuss the basics of the human eye.

A normal human eye is spherical in shape and properly refracts light. When the light is properly refracted, the vision is crystal clear. A person can see in perfect 20/20 vision.

If, however, a person’s eye is shaped like a football or the back of a spoon. In other words, it’s not spherical shaped and is known as being “irregular”. Since it is oddly shaped, the light is refracted in different directions. Thus, the vision is blurry—how blurry depends on the severity of the astigmatism.

Now that you know all of that, you can think of an astigmatism as being a condition of the eye in which the cornea is irregularly shaped. Due to this, the light is refracted in different directions and may cause the eye to be extremely blurry.

Not everyone requires glasses, but nearly everyone has a form of an astigmatism. The reason why not everyone with an astigmatism requires glasses or contact lenses is because not all astigmatisms create extremely blurry vision. Some are so subtle that a person may not even know they have an astigmatism.

Where Does Astigmatism Come From?

There are actually several possible causes of astigmatism, which can make it tough for an eye doctor to tell you where it came from. Astigmatism may be inherited genetically—if your parent has it, chances are you will, too. It can be caused by too much pressure on the cornea by the eyelids or due to incorrect
posture. It may also be caused by an increased use of the eyes for work.

What are the Symptoms?

People who have an astigmatism may experience headaches, fatigue, eye strain and blurred vision at all distances. It is important to note that not everyone experiences all of these symptoms, so just because you experience one symptom and not the other, it doesn’t mean you don’t have an astigmatism.

Is Astigmatism Hard to Correct?

The word astigmatism can be a little scary to some people. That’s because they automatically think of it as being a possibly hard thing to correct. Lucky for them, it isn’t hard to correct at all.

The two most common treatments for astigmatism is the use of glasses or contact lenses. Another possible way to correct astigmatism is to have laser eye surgery which corrects the shape of the cornea.
