Research has shown disparities in the incidence of astigmatism in members of Black, Indigenous, and People of Color BIPOC communities when compared with white populations. Black children, Hispanic children, and Asian children are all at an increased risk of astigmatism compared with non-Hispanic white children.

Astigmatism is when the front surface of your eye, called the cornea or lens, has imperfect curvature rather than being round.
Many people who have mild astigmatism may not even realize it. People who have more severe astigmatism can have symptoms that include blurred vision, eye discomfort, squinting, and headaches. Imagine your cornea is like a sphere, similar to a beach ball — that would be an eye with no astigmatism.
With astigmatism, the cornea is shaped more like an American football. Tests for astigmatism include the following: Visual acuity This test involves reading letters of different sizes on a distance chart. There are alternative methods for children or nonverbal people. Keratometry or topography Both of these tools can measure the curvature of the cornea to measure the astigmatism. The astigmatism measurement is one part of an eyeglasses prescription, says See.
Laser surgery can correct some types of astigmatism; an eye exam is necessary to determine who is a candidate for this type of corrective surgery. Laser-assisted subepithelial keratectomy LASEK In this procedure, the above surgery is performed but the cornea is accessed by loosening the epithelium the protective cover of the cornea with a special alcohol rather than cutting the cornea and creating a flap. Lens removal and replacement with a clear IOL improves vision. Intacs surgery This surgery is an option for some people with keratoconus that worsens to the point where glasses or contact lenses no longer provide clear vision.
Two small plastic crescents called Intacs are placed within the cornea to make the corneal surface more regular, which can improve vision, although glasses or contact lenses are sometimes still needed. Reading Benefit : This exercise helps to release the strain and pressure caused by astigmatism, and must be done 2 to 4 times a day. Exercise 4: Vision Breaks Benefit: This exercise relieves eye pressure and strain.

However, if you do need treatment, options are available, including corrective eyeglasses, contact lenses, and refractive surgery.

If you have vision problems, you should see your eye doctor to take an eye exam and discuss your options to help you achieve clear vision. Astigmatism is an eye condition caused by an irregularly-shaped cornea. People with astigmatism have blurry vision from both near and far distances.
Mild forms of astigmatism usually do not require correction. For those with severe astigmatism, contact lenses, eyeglasses, or surgery may be needed. Astigmatism can be broken down into five categories. Not all astigmatism is the same. Astigmatism can vary in severity. The degree of astigmatism is measured in diopters.
For context, a perfect eye that has no astigmatism has 0 diopters, but some people have between 0. People who have about 1. There are three numbers on any glasses or contact prescription, and the last two refer to astigmatism. Spherical indicates whether you are nearsighted a minus sign or farsighted a plus sign. Cylinder measures the severity of astigmatism. Axis measures where astigmatism is located in degrees from 0 to Nearly 33 percent of Americans have astigmatism to some degree.
Mild astigmatism is considered normal. Most people have it and do not need corrective lenses or surgery to see clearly. You may not even notice any symptoms with a mild case of astigmatism. Moderate astigmatism is a little more serious and generally requires corrective lenses or laser surgery in order for you to see clearly. While you may be able to get by without wearing glasses or contacts, chances are that you will notice the symptoms of moderate astigmatism and glasses and contacts can certainly help.
