Weekly lenses toric
Toric contact lenses for two-weekly dispose
Toric contact lenses are specially manufactured for lens wearers with astigmatism. Astigmatism is defined as an irregular curvature of the cornea that causes a distorted vision. It can be corrected with glasses or special contact lenses. The difference to “normal” spherical contact lenses is only the shape of the lens that needs to fit the astigmatic eye shape.
The deformed cornea is also the reason for the required fixed position of the lens in the eye. The stability is achieved by either a prism in the lower area of the lens or by a blink-induced adjustment, depending on the technology chosen by the manufacturer. The shape of the contact lens is defined through additional specifications, namely the “cylinder” and the “axis” of the lens.
Weekly contact lenses, unlike daily disposables, can be worn up to 14 days. In order to reach such a long wearing period, the lenses have to be cleaned and stored correctly. While taking care of your lenses, always keep in mind that different care products match different contact lenses. Even if the care process is executed correctly, the lenses have to be disposed at least every two weeks to make sure they stay fresh and hygienic. With their extended wearing time and the cleanliness and hygiene, weekly contact lenses combine the advantages of daily and monthly lenses.
