CooperVision's premium daily silicone hydrogel lens — Smart Silicone™ technology and Aquaform® Comfort Science deliver Dk/t 100 oxygen performance with a naturally moist, comfortable 54% water content surface. 30 lenses per box.
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.
🌿 Same lens as the 90 Pack — identical Stenfilcon A material, Smart Silicone™ technology, and Aquaform® Comfort Science. The 30-pack is the monthly ordering format for MyDay wearers who prefer flexibility, or who are trying the lens for the first time before committing to bulk stock.

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.
💡 Tip: Satisfied with MyDay 30 Pack? The 90-pack at contactlens365.com provides the same lens at significantly better per-unit value — the practical upgrade once you have confirmed fit and comfort over a full month of daily wear.
The lens is completely identical in both packs — same Stenfilcon A material, same Smart Silicone™ technology, same Aquaform® Comfort Science, same specifications. The 30-pack provides approximately one month's supply per eye. The 90-pack provides three months per eye and offers a better per-lens price. The 30-pack is the right format for first-time wearers and those who prefer monthly ordering flexibility.
No. MyDay is a daily disposable lens — open a fresh blister each morning and discard the lens at the end of the day. No cleaning solution, no storage case, and no maintenance are required.
A 30-lens box provides approximately one month of supply for one eye, assuming daily wear. Two boxes — one per eye — provide approximately one month for both eyes.
The standard MyDay spherical lens does not correct astigmatism. CooperVision offers a separate MyDay Toric variant — consult your eye care professional about which version is right for your prescription.
No. Contact lenses of any kind should be removed before swimming, showering, or entering a hot tub. Water exposure significantly raises the risk of serious eye infection, including Acanthamoeba keratitis.

No — unless your eye care professional has specifically approved extended wear for you. MyDay is designed for daily wear and should be removed each evening before sleep.
