Product details
Purevision Toric lenses offer sharp and clear vision for those with astigmatism. Offering comfortable and stable vision for both long-sighted and short-sighted users, the high-quality design of these lenses ensures your eyes will stay moist and healthy throughout the day.
Each Purevision Toric contact lens is built from a silicone hydrogel material, which allows more natural oxygen to reach your eyes. An AerGel layer on the surface of the lens, also safeguards your eyes from any debris or harmful protein build-up which might affect your vision. It’s the combination of these materials that ensures your eyes remain white and clear while wearing Purevision Toric lenses.
Because each lens is so comfortable, it is possible to wear Purevision Toric contact lenses for up to 30 days and night’s non-stop without changing them. However, we recommend talking to your opticians before you do so, just to confirm if this will be suitable for your eyes.
Whether you’re working long nights at the office, or spending a day on the road. Purevision Toric lenses will keep your eyes fresh all day and night, so you can stay focused at all times.

Dk/t is common used and it states: the Dk per thickness of the lens. Usually for a lens at -3.00D, which makes it easier to compare different lenses brands.
