How do toric contact lenses stay in the right orientation?
Blinking and movement typically rotate contact lenses on the eyes. But toric contact lenses have features that help maintain the correct orientation for astigmatism.
Here are two ways it’s done:
Traditional prism and peri-ballast
Prism ballast contact lenses are thin at the top, thicker at the bottom, the weighted bottom edge helps keep the lens oriented. With head and eye movements the contact lens may not remain stable due to the effects of gravity.
With eyelid stabilisation
ACUVUE® Toric Contact Lenses use an EYELID STABILISED® design. Harnessing the natural movement of your eyelids, our contact lenses ensure that however active you may be, your vision remains clear and stable.2
