Clinical case studies

How Clearlii lenses perform in the real world—a selection of representative cases across comfort, fitting and visual performance.

Comfort

Dry-eye wearer, daily screen use

A 34-year-old office worker with screen-related dryness switched to Clearlii Vitamin. After two weeks, reported sustained comfort into the evening and reduced end-of-day dryness.

Fitting

First-time wearer, active lifestyle

A new wearer fitted with Clearlii Daily for sport and travel. High first-fit success and easy handling led to confident, independent wear within one visit.

Acuity

Astigmatism, demanding visual tasks

A patient with astigmatism trialled Clearlii Vitamin Toric. Stable orientation and clear acuity supported long, detail-heavy working days.

Oxygen

Long-hours monthly wearer

A commuter needing extended, cost-effective wear moved to Clearlii Monthly Advanced. Silicone-hydrogel breathability maintained white, comfortable eyes across long days.

For practitioners

From data to the chair

Clinical case studies translate trial data into the situations opticians actually face: the screen-fatigued patient, the borderline dry-eye wearer, the lapsed lens user ready to try again. Each case documents the presenting need, the lens selected, the fitting rationale and the measured outcome.

They are designed as practical reference, not promotion—so you can match a Clearlii lens to a real patient profile with confidence.

Using the case library

Can I request the full case data for my practice?

Yes. Registered eye-care professionals can request detailed case documentation and the underlying study summaries through our partnerships team.

Are these cases peer-reviewed?

Our case studies draw on internal clinical data and peer-reviewed literature. Each references its source so you can evaluate the evidence yourself.

How do I match a case to my patient?

Cases are organised by presenting need—dryness, screen use, astigmatism, lapsed wear. Find the closest profile, then confirm the fit with your own assessment.
