Clearlii Monthly Advanced
A silicone-hydrogel monthly lens that contributes high oxygen flow to the eye. Thanks to the lens’s effective moisture retention, it delivers high comfort and sharp vision in every situation.
The science behind our perfected comfort
Every Clearlii Monthly Advanced lens combines several key technologies, engineered to work together for all-day comfort and clarity.
Silk & Soft Edge Design
A unique edge design for increased mobility and tear-fluid flow beneath the lens, for a more stable tear film—while the soft design minimises friction against the eyelid.
UV protection
UVA and UVB protection that helps shield your eyes from the sun’s harmful UV rays.
Silicone hydrogel
The silicone-hydrogel material contributes to increased oxygen supply, maintaining clear and unirritated eyes with good visual acuity all day.
Backed by evidence, not promises
Every Clearlii Monthly Advanced lens is developed through extensive research, independent testing and real clinical studies—so both wearers and clinicians can choose with confidence.

Evidence from every angle
Multicenter studies confirm superior moisture retention and comfort, with over 95% of participants rating the experience "excellent" or "very good".
II.
Measured, not marketed
From oxygen permeability to a stable tear film, every metric is verified by independent laboratories to ISO standards.
III.
Trusted in daily practice
