The benefits of silicone hydrogel lenses have been widely accepted by practitioners fitting 2-week or monthly disposable contact lenses. In fact, data suggests that approximately 88% of frequent replacement lenses are prescribed in silicone hydrogel materials. But that same data suggests that only about 22% of 1-day lenses are prescribed in SiHy.1 Should practitioners be embracing silicone hydrogel materials for daily disposable wearers as well? Absolutely! It has been reported that 1-day wearers in the United States wear their lenses for an average of 15 hours per day, 7 days per week.2 In light of those wearing habits, it certainly makes sense to maximize oxygen transmissibility for 1-day patients as well.
CooperVision is aware that 1-day lens wearers want it all: superior, long-lasting comfort, healthy breathability, effortless handling and UV protection. Unfortunately, they’ve traditionally had to compromise. Hydrogel lenses offer high water content, but low oxygen transmissibility. Silicone hydrogel lenses transmit oxygen superbly, but many have lower water content and may be less comfortable. The challenge that was therefore presented to CooperVision materials scientists was to develop a lens material that doesn’t compromise on comfort, breathability or ease of handling.
The solution came in the form of Smart Silicone® chemistry: the revolutionary hydrophilic long-chain molecule at the heart of MyDay’s sophisticated material. This 3rd generation silicone hydrogel material utilizes less than 5% silicon, allowing for >50% water content. With a modulus ≤0.4, it is the softest SiHy daily lens CooperVision offers. MyDay® lenses take silicone hydrogel 1-day lens performance to the next level, allowing practitioners to prescribe the ocular health advantages± of a high Dk material, while delivering your patients excellent all-day comfort, easy lens handling and UV protection.±±
MyDay® lenses excel in the key areas that matter most to you and your patients:
- HEALTHIER LENS WEARING EXPERIENCE: Silicone hydrogel material with a Dk/t of 100
- ALL-DAY COMFORT: Naturally water-loving lens material
- EASY HANDLING: Soft like a hydrogel lens, but with silicone hydrogel handling
- EXCELLENT VISUAL ACUITY: Aspheric optics
- UV PROTECTION: Inhibits 85% of UVA and 96% of UVB harmful rays
- FULL POWER RANGE: +8.00D to -12.00D parameters
- FITTING VERSATILITY OF CORNEAL CURVATURES±±±: Soft, low modulus 0.4MPa

± With higher oxygen permeability than hydrogel materials, silicone hydrogel contact lenses minimize or eliminate hypoxia-related signs and symptoms during lens wear.
±± Warning: UV-absorbing contact lenses are not substitutes for protective UV-absorbing eyewear, such as UV- absorbing goggles or sunglasses, because they do not completely cover the eye and surrounding areas. Patients should continue to use UV-absorbing eyewear as directed
