TopVue Air for Astigmatism are toric contact lenses design to correct astigmatism. They are made of an innovative silicone-hydrogel material. TopVue Air for Astigmatism are characterized by high oxygen permeability and a high water content. The design of TopVue Air for Astigmatism contact lenses uses progressive technology that provides stable positioning of contact lenses on the eye, in every situation, throughout the day.
TopVue Air for Astigmatism contact lenses
feature a stabilization technology called SHT PrismBallast, which helps
to achieve the perfect positioning of the lens on the eye. The prism ballast
design makes the lower part of the lens thicker, using gravity to facilitate a
perfect fit on the eye. The SHT PrismBallast technology eliminates the rotation
and movement of the lenses, because the mass of the ballast is distributed in a
Because of their special shape and distribution of mass, TopVue Air for Astigmatism contact lenses provide smooth movement for the eyelid over the whole area of the eyeball. The natural process of blinking also helps the lens to stabilize. The lenses work with the unique motion of your upper and lower eye lids to help keep the lenses in place.
TopVue Air for Astigmatism contact lenses are packaged in a blister pack filled with a solution that is fortified by added sodium hyaluronate. Sodium hyaluronate has absolute compatibility with the physiological environment of the eye. Thanks to the sodium hyaluronate solution, TopVue Air for Astigmatism lenses are comfortable from the first use.
The innovative technology of silicone-hydrogel materials allows TopVue Air for Astigmatism to transport atmospheric oxygen to the cornea through microscopic channels at a very high rate. This ability to transfer oxygen (transmissibility) is 100 Dk/t in TopVue Air for Astigmatism. Another important parameter of all contact lenses is their water content. TopVue Air for Astigmatism contains 45% water. Thanks to their high water content, they remain sufficiently hydrated throughout the day. This high water content also reduces deposits on the lens surface and minimizes the risk of infection.
