TopVue Premium for Astigmatism are toric contact lenses designed to correct astigmatism. They are made of a modern silicone-hydrogel material. The shape of the TopVue Premium for Astigmatism lenses ensures the stability of the lens in the eye. TopVue Premium for Astigmatism is characterized by high oxygen permeability with a high water content.

The ability to transport oxygen molecules in TopVue Premium for Astigmatism lenses is 104 Dk / t. Oxygen is carried from the air to the cornea of the eye through microscopic channels.

TopVue Premium for Astigmatism toric lenses are packed in a blister pack and are immersed in a liquid enriched with a moisturizing substance - sodium hyaluronate, which is compatible with the natural environment of the human eye. Thanks to this, the eyes are moisturized, which prevents possible irritation, and the lenses are comfortable to wear throughout the day.

Astigmatism is a visual defect characterized by a disturbed rotational symmetry of the eye, caused by the irregular shape of the cornea or lens. To provide an effective solution in the correction of astigmatism, the cylinder and degree of the lens axis must be specified.

The special shape and mass distribution of the TopVue Premium for Astigmatism lens means that the lens is not felt when blinking, and the eyelid moves naturally over the lens. The natural blinking process also helps to keep the lens stable. This is very important with toric lenses because the stable lens ensures that the cylinder and axis are exactly where they are correcting in the eye.
