Astigmatism Q & A

What is astigmatism?

Astigmatism isn’t a disease; it simply means your eyeball isn’t perfectly round. A round eyeball enables incoming light to bend evenly, giving you clear vision. If you have astigmatism it means your eyeball is shaped more like a football, so light bends unevenly. The uneven bending of light makes your vision blurry because only a part of what you’re looking at is in focus.

Astigmatism can be mild or severe, and it can change over time. Your optometrist at ReVision Optix can provide you with the right glasses or contact lenses to correct your vision and enable you to see clearly.

Why would I have astigmatism?

Astigmatism is usually something you’re born with, and it commonly runs in families. There’s no known reason why some people have differently shaped eyeballs, but it’s a natural phenomenon and doesn’t indicate you have any health problems.

Some people develop astigmatism after injuring their eye or suffering an eye disease, and it can occasionally develop after eye surgery. You can’t bring on astigmatism by straining your eyes to read in low light or by sitting close to the television.

How do I know if I have astigmatism?

Your optometrist can pick it up during your routine eye exam. If you’re experiencing blurry vision, you should make an appointment at ReVision to get your eyes checked. You might have other problems, such as near- or farsightedness, which can also cause blurry vision.

Your optometrist can tell by examining your eyes whether you have astigmatism and, if necessary, prescribe the right glasses or contact lenses to correct the problem. If your astigmatism is only slight, you might not need any treatment.

Another option is refractive surgery, which involves using a laser to change the shape of your cornea, but most people with astigmatism can see perfectly well with the right glasses or contacts.

Your optometrist can create lenses for your glasses that counteract the shape of your eye and enable you to see clearly. If you wear contact lenses, you need special lenses for astigmatism called toric lenses.

Standard contacts move around as you blink, which makes no difference if your eye is round. However, with astigmatism, your eye is more football shaped, so if the lens moved to a different position your vision would get blurry again. Toric lenses do move when you blink, but to keep your vision in focus, they return to their original position.

If you have blurry vision, it could just be a simple case of astigmatism that your optometrist can easily correct for you, so call ReVision Optix today to book an appointment, or use the online tool.
