Astigmatism symptoms causes and treatment

Astigmatism Symptoms, Causes, and Treatment

Many people suffer from different eye issues. One of these is astigmatism, which has symptoms and causes that can be difficult to diagnose. It can be hard to differentiate between it and other conditions. That’s because it’s quite like nearsightedness or farsightedness.

The good news is that treatments are available for those who suffer from this condition. But before you go for treatment, you must understand the diagnosis and treatment options available.

You should also know the causes and symptoms of this condition. This way, you can identify it correctly when visiting an eye specialist or doctor.

This article is a comprehensive guide to astigmatism. We’ll cover its symptoms, causes, and treatment options.

Astigmatism Correction and Treatment

Currently, there are two ways to treat astigmatism:z

  1. Prescription glasses or contact lenses

There are several prescription glasses next day online services. They help you get a pair of glasses or contact lenses within 24 hours. These services are available in most cities and towns. So you can easily order your lenses online and pick them up from the nearest store.

  1. Refractive surgery

Refractive surgery is an effective way to treat astigmatism. It can be performed under local anesthesia and doesn’t require incisions. An eye surgeon will reshape your cornea during the procedure. They’ll use a laser or other medical device to improve vision.


Before your doctor decides on a treatment option for astigmatism, you need an eye exam. Some ways they do this include:

Eye chart

An eye chart is a series of small letters in different sizes and colors. When an eye chart is done, you can opt for prescription glasses next day depending on diagnosis of the eye doctor. The eye doctor will ask you to read these letters from left to right while they measure your visual acuity. An example of an eye chart is the Snellen letter chart. It has rows of letters progressing from one through six.


A phoropter is an instrument with a series of lenses with different powers. The doctor will ask you to put each lens on and read the letters from left to right. They will measure your visual acuity through these lenses. Then they’ll find the one that gives you sharp vision without glasses or contact lenses.


An autorefractor is a machine that measures your visual acuity. You will sit in front of the machine and look at a series of lights or images. The machine will take measurements while you do this. Then your doctor will determine what kind of prescription lenses you need to see clearly.


A keratometer is a measuring device that measures the curvature of your cornea. It looks like a small machine with a lens on top and light below it. Your doctor will put drops in your eyes to dilate them so they can see better. Then put this instrument in front of one eye while you look at lights through the lens.

Causes of Astigmatism

Now, let’s examine the causes of astigmatism. You first need to understand that your eyes have two curves in them. These are the cornea and the lens.

The cornea is the clear part of your eye that covers the iris, the colored part of your eye. The lens sits behind this covering and focuses light on your retina. This signals your brain so you can see clearly.

These two conditions can cause astigmatism:

A refractive error

This is the most common cause of astigmatism. It occurs when there is a difference between the curvature of your cornea and the lens. This causes light to focus in front of or behind where it should be. This defect may also be present from birth. You can correct a refractive error with eyeglasses or contact lenses.

Other refractive errors

Other refractive errors may also cause astigmatism. These can be hyperopia (farsightedness) or myopia (nearsightedness). The cornea is too steep in hyperopia, causing light to focus behind your retina. In myopia, your cornea is too flat, and light focuses in front of your retina.

Astigmatism can also occur if the curvature of the cornea and lens are different in each eye (anisometropia). This is more common among children with Down syndrome. This is because they have a longer eyeball length than average.

Symptoms of Astigmatism and When to See a Doctor

Astigmatism has various symptoms, including blurry vision, headaches, and eye strain. You may also experience glare or halos around lights at night. The symptoms of astigmatism vary depending on how much you have and how severe it is.

You must visit your eye doctor if you experience any of these symptoms. If you have astigmatism, your doctor may recommend wearing glasses or contact lenses to correct the problem.

As for children, you need to observe them as they can develop the condition at a very young age. If you notice that your child has trouble seeing clearly or focusing, schedule an appointment with your doctor.


Astigmatism is a common eye condition. It can affect your vision and cause discomfort. If you have astigmatism, wearing glasses or contact lenses may help correct the problem. See your eye doctor if you notice any of the symptoms of astigmatism listed above.
