How Do I Know if I Have Myopia or Astigmatism?

It’s not always easy to tell whether your blurry vision is caused by myopia (nearsightedness) or astigmatism, as both conditions can make it difficult to see clearly. However, understanding the differences can help you know when it’s time to schedule a comprehensive eye exam to find the right solution for your vision.

What Is Myopia?

Myopia, or nearsightedness, occurs when the eye is slightly longer than normal or the cornea is too curved. This causes light entering the eye to focus in front of the retina instead of directly on it. As a result, distant objects appear blurry, while close-up tasks such as reading or looking at your phone remain clear.

Common symptoms include:

• Blurred distance vision (especially when driving or watching TV)

• Squinting to see faraway objects

• Eye strain or headaches after trying to focus on distant targets

Myopia often develops during childhood and can progress with age, which is why regular eye exams are so important for both kids and adults.

Understanding Astigmatism

Astigmatism occurs when the cornea or lens has an irregular shape—more like a football than a basketball. This irregular curvature causes light to focus unevenly on the retina, leading to blurred or distorted vision at all distances.

Common symptoms include:

• Blurry or distorted vision up close and far away

• Difficulty seeing clearly at night

• Eye fatigue and headaches after prolonged visual tasks

Astigmatism can occur alongside myopia or hyperopia (farsightedness), which is why professional testing is needed to determine your exact prescription.
