Your optician will be able to check your eyes to see if you have astigmatism. If you have it, it’s not the end of the world – it’s quite a commonly-occurring condition.
HOW CONTACT LENSES FOR ASTIGMATISM WORK
Toric contact lenses have different powers in different parts of the lens. They are made to stabilise to the correct position on the eye. This is unnoticeable by the wearer but gives people with astigmatism clear vision.
Disposable contact lenses that last 30 days. Clean and store them every day.
*** Dk/t=175 @ -3.00D. Compared to any monthly reusable lens.
† Most breathable daily disposable lens dk/t=156 @ -3.00D. Compared to any branded daily disposable lens
†† AIR OPTIX® NIGHT & DAY® AQUA lenses are approved for daily wear and for up to 30 nights continuous wear. Not everyone can wear lenses for a full 30 nights. Please consult your optician.
