Frequently Asked Questions about AIR OPTIX® for Astigmatism Contact Lenses

Q: What is astigmatism?

Astigmatism is a slight difference in the shape of your eye, causing fuzzy, blurred vision at all distances. The oval shape of eyes with astigmatism causes images to be processed differently than eyes with a more circular shape, as shown below.

Eye with astigmatism

Because astigmatism causes images to be processed at two points on the back of the eye, each lens that corrects for astigmatism require two prescriptions that must remain in the same place relative to the eye. If the lens rotates, vision will become blurry. So, lens stability is key to consistently clear vision.

Q: What are toric contact lenses?

Eye

Contact lenses that correct astigmatism are called toric contact lenses. They are made specifically to address the slight difference in shape of your eye that can cause fuzzy, blurred vision. A toric contact lens has two prescriptions—one to correct astigmatism, and the other to correct near- or farsightedness. They are designed to remain stable on the eye and not rotate as you blink or move your eyes.
