CooperVision MyDay® Daily Disposable 30 Pack is CooperVision's flagship premium daily silicone hydrogel lens — available at contactlens365.com in the convenient 30-lens monthly format. The MyDay is built on Stenfilcon A with two proprietary technologies that together solve the central tension of silicone hydrogel lens design: Smart Silicone™ achieves Dk/t 100 oxygen transmissibility without sacrificing water content, and Aquaform® Comfort Science integrates moisture structurally throughout the material rather than relying on surface treatments that deplete over the course of the day.

The result is a daily disposable lens with 54% water content and Dk/t 100 — a combination that most silicone hydrogel platforms cannot achieve simultaneously. Where conventional silicone hydrogels trade lower water content for higher oxygen performance, Smart Silicone™'s unique molecular architecture provides both. For wearers who have previously had to choose between oxygen performance and all-day moisture comfort, the MyDay 30 Pack represents a genuinely different option in the daily lens category.

Product Details

Smart Silicone™ technology addresses a fundamental limitation of conventional silicone hydrogel design. Standard silicone hydrogels achieve high Dk/t by packing silicone molecules densely within the polymer network — which necessarily displaces water and produces lenses that typically contain 33–46% water. Smart Silicone™ uses fewer, larger silicone units that achieve the same oxygen transmissibility while preserving significantly more of the polymer's volume for water retention, producing a 54% water content alongside Dk/t 100 in the same daily lens.

Aquaform® Comfort Science complements Smart Silicone™ by ensuring the high water content is maintained throughout the wearing day rather than progressively lost. Because moisture is structurally integrated within the Stenfilcon A material rather than applied as a surface wetting agent, it does not deplete with blinking, handling, or exposure to challenging environments. The wearing experience at hour 14 is therefore genuinely comparable to hour 1 — not a gradual decline from comfortable to acceptable.

The 30-pack provides approximately one month's supply per eye, making it the right format for first-time MyDay wearers evaluating the lens before moving to the 90-pack, or for wearers who prefer the flexibility of placing a fresh order each month. The 90-pack version of MyDay is available at contactlens365.com for those who prefer the economy format — the lens specification is identical in both pack sizes. Always confirm your current prescription with your eye care professional before ordering.

Who Is It For?

How to Use

• 1Wash your hands thoroughly with soap and water. Dry with a lint-free towel before handling any lens.
• 2Open the blister carefully — peel back the foil without squeezing the pack.
• 3Check orientation — the lens should form a smooth bowl shape. Flared edges mean it is inside-out. Never insert an inside-out lens.
• 4Insert gently by holding lids open and placing the lens onto the cornea. Blink to settle.
• 5Check comfort and vision. Discomfort or blur? Remove, inspect, and reinsert. Persistent issues — consult your eye doctor.
• 6No solution needed. As a daily disposable, no lens case or cleaning solution is required.
• 7Remove before sleep unless your eye doctor has specifically approved overnight wear.
• 8Discard after one day. Never reuse a daily disposable lens.
