CooperVision Releases MyDay Silicone Hydrogel Daily Disposables in U.S.

CooperVision, Inc., has introduced its MyDay silicone hydrogel daily disposable contact lenses to the U.S. market, noted the company in a emailed press release. The new daily disposable lenses are made with Smart Silicone chemistry, a technology that delivers the benefits of both hydrogel and silicone hydrogel lenses, according to CooperVision. Smart Silicone optimizes oxygen permeability in a lens that is just 4.4% silicon—the lowest percentage of silicon found in a silicone hydrogel, daily disposable lens. By using less silicon, Smart Silicone leaves more room in the lens for built-in channels of comfort-enhancing moisture. It also enables a modulus of only 0.4 MPa—lower than any other 1-day silicone hydrogel lens—to make MyDay the softest silicone hydrogel daily disposable available. And while the lens provides the optimal softness of a hydrogel, it remains strong enough to ensure the exceptional handling of a silicone hydrogel lens.

With a smooth lens surface and rounded edge, MyDay daily disposable lenses reportedly provides a more natural feeling as the eyelid glides effortlessly over the lens. Testing shows that the lenses not only have immediate comfort at insertion, but they have excellent comfort over the course of the day. MyDay lenses are naturally wettable, unlike surface coated lenses. Built-in UV protection filters 85% of UVA and 96% of UVB rays, helping promote long-term ocular health. CooperVision first introduced MyDay lenses in Europe in June 2013, then rolled out distribution to Australia and New Zealand in early 2014.

MyDay daily disposable lenses feature sphere powers from +6.00D to -10.00D (0.50 steps after +5.00D and -6.00D); a base curve of 8.4mm; a diameter of 14.2mm; a Dk/t of 100 (@ -3.00D); and a modulus of 0.4 MPa.
