When we call moody+ S-Series “medical-grade,” we mean it in the way eye care professionals do: defined materials, measurable performance, and safety-first verification—not marketing buzzwords.
S-Series is built on olifilcon A, a silicone hydrogel material chosen for a single mission: a true “Rest Day” lens that supports clear comfort on the days your eyes need a reset—especially if you experience dryness, sensitivity, or long screen hours.
Below is what “clinically guided” means in practice.
Material-Level Medical Evaluation, Not Assumptions
In the contact lens industry, the strongest safety signals come from structured evaluation—including biocompatibility, ocular response, and real-world comfort endpoints.
For the silicone hydrogel technology behind S-Series, material-level evaluations and pre-market assessments have been conducted in collaboration with leading teaching hospitals and medical centers in Taiwan as part of a partner-led medical validation process.
Why it matters: clinical evaluation helps translate lab performance (like oxygen transmissibility) into real-world ocular comfort indicators, such as reduced hypoxia-related stress and better long-wear tolerance.
Important clarity: Hospitals may evaluate materials or lens technologies as part of broader research and pre-market programs. Specific protocols and datasets may not always be publicly shareable due to institutional and regulatory constraints.

While traditional hydrogel lenses often deliver an oxygen transmissibility ($Dk/t$) of around 20–30, the S-Series delivers a breakthrough 187.5 $Dk/t$—effectively providing up to 6x more oxygen to your cornea compared to standard color lenses. In plain terms, olifilcon A is engineered to help provide: - High oxygen transmissibility (Dk/t) to support a well-oxygenated cornea - Soft, low-stiffness comfort to reduce “lens awareness” - Stable surface hydration for smoother blinking and less dryness This is why S-Series is positioned as a weekday comfort partner—the lens you choose when your priority is ocular comfort and eye-friendly wear.
