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.
