Moisturising lenses with hyaluronic acid
Lock in moisture for all-day comfort. Hyaluronic acid creates a moisture reservoir that keeps the lens hydrated through most of the day—reducing dryness even during long, screen-heavy hours.
Why hyaluronic acid matters
The top comfort benefits, at a glance.
01
Instant hydration on insertion
A cushion of moisture from the very first blink for a fresh, comfortable start.
02
Sustained release for 16+ hours
Moisture is released gradually through the day rather than lost in the first hours.
03
Improved tear-film stability
A more stable tear film means clearer vision and less end-of-day dryness.
How hyaluronic acid keeps you hydrated
Hyaluronic acid (HA) is a natural moisturiser that binds water molecules at the lens surface. Embedded in the lens, it is released with each blink and integrates into your tear film.
The evidence
Independent and internal testing substantiates the moisture-retention benefits.
Reduction in reported end-of-day dryness in internal wearer testing.
Sustained surface hydration across a typical wearing day.
of trial wearers rated comfort “good” or “excellent”.
"Our optimised HA matrix releases moisture exactly when the eye needs it—at the blink—so comfort stays consistent from morning to night."

Hydration & comfort
How does hyaluronic acid improve comfort?
Hyaluronic acid (HA) is a powerful moisturiser that binds water molecules, keeping the lens surface hydrated. Clearlii lenses release HA gradually through the day, reducing dryness and maintaining comfort in screen-heavy or dry environments.
What role does vitamin enrichment play?
Clearlii Vitamin lenses contain micro-encapsulated vitamin E, an antioxidant that combats oxidative stress from UV light, pollution and digital devices. This helps reduce the sensation of fatigue and irritation.
Do Clearlii lenses protect against blue light?
Yes. Select Clearlii designs include UV and blue-light filters that protect against harmful rays while still allowing beneficial light to pass through - particularly helpful for wearers with high screen exposure.
