Astigmatism Diagnosis
Astigmatism symptoms come on slowly. Go to an eye doctor if you notice changes in your vision. You’ll need a complete eye exam. Your doctor will test the sharpness of your eyesight by asking you to read an eye chart.
Astigmatism tests
Your doctor will also use tools to measure your vision, including:
Phoropter. You look through a series of lenses to find the ones that give you the clearest vision.
Keratometer. This machine measures the bend in the center of your cornea. It finds the steepest and flattest curves. The measurements tell your doctor about the shape of your cornea and how well it can focus.
Autorefractor. This device shines light into your eye and measures how it changes as it bounces off the back. This gives your doctor an idea of which lenses you need.
Corneal topographer. This technology gives the most detailed information about your cornea’s shape. The doctor tells you to look at a specific point. Meanwhile, the device collects thousands of tiny measurements. A computer builds a color map of your cornea from the data. Your doctor will refer to it if they plan surgery for astigmatism or cataracts. They might use it to fit contacts. It can also help diagnose keratoconus.

Contact lenses can also help, but you’ll need a special pair.
All contacts rotate when you blink. The soft lenses used for astigmatism, called toric lenses, are designed to return to the same spot each time.

What Is Astigmatism?
Astigmatism is a common eye condition that can cause blurry vision. How common is it? We surveyed 450 people who wear prescription glasses or contact lenses and found that nearly half (48%) have astigmatism.
Astigmatism occurs when the eye isn’t perfectly round. For example, instead of being shaped like a sphere, the eyeball is shaped more like an egg.
When your cornea and/or lens are not round, light refracts differently creating two images that overlap and cause blurry vision.
A perfectly round eyeball distributes light evenly throughout your cornea for clear vision. If your eye is shaped more like an egg or football, the light entering your eye will bend more in one direction.
The two general types of astigmatism are:
Horizontal: Your eye is wider instead of taller.
Vertical: Your eye is taller instead of wider.
For many people, the astigmatism isn’t severe enough to warrant corrective action; however, if you do have a more severe astigmatism, it is treatable with corrective lenses or refractive surgery, like LASIK.
