Understanding Astigmatism with an Optometrist Near You: Causes and Symptoms

Clear vision is something most folks don’t think twice about—until it’s gone. Astigmatism is one of those eye conditions that can quietly blur the edges of your world. At Vision Source Fredericksburg Road, your eye doctor in San Antonio, TX, we sometimes see patients who’ve lived with it for years without even knowing. It’s more common than many realize, and thankfully, it’s manageable with the right care.

What Is Astigmatism?

Astigmatism happens when the front surface of the eye—called the cornea—isn’t shaped the way it should be. Instead of being round like a basketball, it’s more like a football. That uneven curve causes light to bend in different directions as it enters the eye. The result? Blurry or distorted vision at both near and far distances.

Some people also have lenticular astigmatism, which means the lens inside the eye is misshaped too. Either way, the eye struggles to focus light correctly on the retina, and things don’t look quite as sharp.

What Causes It?

Most of the time, astigmatism is something people are born with. It can also develop as the eyes grow or change over time. In other cases, it may come after an eye injury, surgery, or a condition called keratoconus, which causes the cornea to thin and bulge.

It’s not caused by reading in the dark or sitting too close to the TV—those are old myths. The shape of the eye is mostly determined by genetics and natural development.

Common Symptoms

The signs of astigmatism can be subtle at first. Some folks may just think they’re tired or need to blink more. But over time, the symptoms usually become more noticeable. They can include:

• Blurred or fuzzy vision

• Headaches, especially after reading

• Eyestrain or squinting

• Trouble seeing clearly at night

• Difficulty focusing on fine details

Getting Diagnosed

An eye exam is the only way to know for sure. During your visit, we’ll check how your eyes focus light, measure the shape of your cornea, and find out what kind of prescription you need—if any. It’s a quick and painless process that can make a world of difference.
