Astigmatism, Explained
Can You Wear Color Contacts?
If your eye doctor has mentioned astigmatism, or you're just trying to understand blurry vision that doesn't quite fit "nearsighted" or "farsighted," you're in the right place. Here's what astigmatism actually is, and what it means if you're hoping to wear color contacts.
What Is Astigmatism?
Astigmatism happens when the cornea (the clear front surface of your eye) isn't perfectly round. Instead of a symmetrical curve, it's shaped more like a football than a basketball. This causes light to focus at more than one point instead of a single point on the retina, which results in blurred or distorted vision at any distance, near or far.
It's extremely common. Most people have some degree of astigmatism, and many don't notice it unless it's significant enough to affect daily vision.
What Causes Astigmatism?
Astigmatism is mostly about the shape of your eye, and a few things influence that:
- Genetics — it often runs in families
- Eye injuries — trauma that affects the cornea's shape can cause or worsen astigmatism
- Eye surgery or conditions — some procedures or corneal conditions can change its curvature over time
Astigmatism Symptoms
Common signs include:
- Blurry or distorted vision at any distance
- Eyestrain or headaches, especially after reading or screen time
- Squinting
- Difficulty with night vision
If any of this sounds familiar, a comprehensive eye exam with an optometrist is the best next step. They can measure the exact shape of your eye and let you know what's going on.
Can You Wear Color Contacts With Astigmatism?
Here's the honest answer: standard color contacts are designed to be spherical, meaning they correct vision evenly across the lens. If you have astigmatism, a standard lens can rotate on your eye and may not sit or feel the way you'd expect, and it won't address the specific distortion astigmatism causes.
Lenses designed specifically for astigmatism are called toric lenses, which are weighted and shaped to stay in a fixed position on the eye. At Dimple Color, we don't currently offer toric color lenses. If you have astigmatism and want to wear color contacts, the best move is to talk to your eye doctor about your options. They can tell you whether your degree of astigmatism is mild enough to work with a standard lens, or whether you'd need a toric fit elsewhere.
Astigmatism vs. Myopia
Myopia (nearsightedness) means distant objects look blurry while close-up objects stay clear. Astigmatism is different: it causes blurred or distorted vision regardless of distance. It's possible to have both at once.
Astigmatism vs. Hyperopia
Hyperopia (farsightedness) means close-up objects look blurry while distant objects stay clearer. Astigmatism, again, affects vision at all distances rather than just close-up work. Many people have some combination of the two.
