CooperVision® MyDay® lenses are made with Smart Silicone™, a revolutionary new hydrogel silicone lens material that uses less silicone and delivers more oxygen to your eyes compared with other brands. Why less silicone? This design leaves more room for moisture, which makes these lenses exceptionally breathable and good at providing all-day comfort. The sleek design also helps with easy insertion and removal, is healthier for your eyes, and gives the lenses a softer feel. These are the kinds of lenses that will make you forget you are wearing lenses at all!
