Could special contact lenses slow worsening eyesight in young adults?
NCT ID NCT05955638
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether dual focus contact lenses (MiSight) can slow the progression of nearsightedness (myopia) in university students aged 18 to 21. Participants wear either the test lenses or standard single vision lenses for at least 10 hours a day. Researchers measure changes in eye length and prescription over time to see if the lenses reduce worsening eyesight.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- MiSight dual focus soft contact lenses
- What this could lead to
- If effective, these lenses could offer a way to slow worsening nearsightedness in young adults, reducing the need for stronger prescriptions.
- What could go wrong
- This is a small, early-stage study in a specific age group. Results may not apply to all myopes, and the lenses may not slow progression for everyone.

Inclusion Criteria: * Be a myopic students studying at university * Be aged 18-21 years at the start of the study * Show evidence of recent myopia progression prior to commencement of Stage 2 of the study. * Have read the patient information sheet and be happy to sign the consent forms * Be willing to adhere to the visit schedule and wearing times described in this protocol * Agree to lens wearing times of at least 10 hours per day, 6 days per week * Agree to accept either the control or test lens as assigned by the randomisation * Have BCVA of +0.10 logMAR or better in each eye Exclusion Criteria: * Previous myopia control use (optical or pharmacological) * Amblyopia * Ocular pathology such as keratoconus or recurrent corneal infections * Myopic Rx \> 10D * Astigmatism \>1D * Anisometropia \>1.75D * Binocular Vision anomalies (such as Tropia) * Medications that affect pupil size or accommodation * A known allergy to fluorescein or tropicamide * Biomicroscopic findings that would contraindicate contact lens wear * The investigator considers that it is not in the best interest of the subject to participate in the study.
