Clariti® 1 Day Toric contact lenses are now manufactured by CooperVision specifically for those who suffer from astigmatism. CooperVision manufacture these contact lenses from silicone hydrogel which not only provides excellent all-day wearer comfort but in addition allows the highest levels of oxygen to pass through to your cornea ensuring the best possible eye health. The unique aspheric design offers clear all-day vision whilst the patented AquaGen® technology ensures your contact lenses stay comfortably moisturized throughout the day. In addition, the special aspheric back surface optimizes the lens position on the eye again aiding visual clarity. Clariti® 1 Day Toric monthly contact lenses come with UVA and UVB filters to help protect your eyes from harmful radiation. Sunglasses are still recommended, however.
