When we go to the eye doctor for a check-up, we are often told that we have both presbyopia and astigmatism, or nearsightedness and astigmatism. What is astigmatism? Is it caused by nearsightedness or farsightedness? How can we treat astigmatism? This blog answers your questions.

What is astigmatism?

Astigmatism is the inability of parallel rays of light entering the eye to focus accurately on a single point, preventing the formation of a clear image. It occurs because the curvature of the eye's refractive tissue (mainly the cornea) is not a perfect sphere.

Astigmatism can be categorized into regular astigmatism and irregular astigmatism. Patients with regular astigmatism see images with a clear offset direction, while patients with irregular astigmatism see images that are a mess.

In addition to vision loss, astigmatism patients are also prone to visual fatigue. Visual fatigue is mainly manifested by symptoms such as dizziness, headaches and nervousness. In addition, patients with highly asymmetrical degrees of astigmatism in both eyes tend to tilt their heads to clear their vision. This can cause strabismus. Teenagers with astigmatism who are not treated in time can also develop amblyopia.

How does astigmatism develop?

Astigmatism can be congenital, associated with certain genetic factors. It may also be acquired:

Bad eye habits, such as lying down or sitting in a rocking car, reading a book, or using a cell phone. These behaviors can put a lot of strain on your eyes.

Failure to correct vision in a timely manner. Nearsightedness or presbyopia without timely glasses or use of inappropriate lenses. The patient often squints to see clearly, and the eyeball is squeezed by the eye muscles for a long time.

External Pressure. An impact to the eye or prolonged exposure to high pressure and strong environments can also distort the cornea and create astigmatism.

Although astigmatism is often discussed along with presbyopia or nearsightedness, they are not necessarily related. People without nearsightedness or presbyopia can also suffer from astigmatism.

What should we do?

There are three ways to treat astigmatism: wearing glasses, wearing corneal contact lenses, and undergoing surgery. Wearing glasses is undoubtedly the easiest, most affordable, and safest method.

First, you need to get a prescription from a professional eye doctor and then buy a pair of nearsighted or reading glasses with the right prescription. You can buy them at the doctor's office, or you can pick up a stylish and personalized pair of glasses online based on your prescription.
