Buy Toric Contact Lenses Online in Australia
Toric Contact Lenses are contact lenses used for people who require correction for astigmatism. There are a variety of designs for toric contact lenses. The most common design is the prism ballast design seen in Purevision Toric, Softlens Toric and Air Optix for astigmatism. These contact lenses have a design which is thicker at the base and thinner at the top. The effect of this design orientates the contact lens into the 6 o'clock position using the effects of gravity, this keeps the lenses in a stable position and therefore can be used to correct astigmatism. The Acuvue range of contact lenses use a different design which they have patented as ASD - Advanced Stabilisation Design. In this toric contact lens, the design has a thicker top and bottom. The contact lens maintains its position by its interaction with the wearers eyelids which hold the lens in its position. The advantage of this design is that it maintains its orientation even if the wearer tilts his head. Toric contact lenses great for correcting astigmatism and are available in all the advanced materials seen in spherical contact lenses.
