Can a lens put the brakes on worsening Short-Sightedness?
NCT ID NCT07804043
First seen Sep 04, 2026 · Last updated Sep 04, 2026
Summary
This trial tests whether special eyeglass lenses, called Stellest 2.0, can slow the progression of short-sightedness (myopia) in young adults compared with standard lenses. Participants will wear either the special lenses or standard ones for at least 12 hours a day for two years. Researchers will measure changes in eye length and prescription strength to see if the special lenses make a difference. They will also check how comfortable the lenses are during the first few months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Essilor Stellest 2.0 myopia-slowing eyeglass lenses
- What this could lead to
- If effective, these lenses could offer a non-invasive way to slow myopia worsening in young adults, potentially reducing the need for stronger prescriptions and lowering the risk of eye complications later in life.
- What could go wrong
- The trial is relatively small and focuses on young adults, so results may not apply to other age groups. The lenses may not slow myopia as much as hoped, and some people might find them uncomfortable to wear for the required 12 hours a day.

Inclusion Criteria: * Spherical equivalent (SE) measured under cycloplegia using an autorefractometer, within the range 4 D ≤ SE ≤ -0.75 D for each eye * Not currently receiving, nor having received, any preventive treatment for myopic progression in the 12 months prior to inclusion (orthokeratology, soft defocus contact lenses, low-concentration atropine eye drops, corrective spectacles with peripheral defocus) * Myopic progression of at least -0.25 D in at least one eye during the year prior to inclusion (measurements documented by autorefractometer, with or without cycloplegia, or via previous optical prescriptions) or documented progression of axial length of +0.1 mm during the year prior to inclusion * Primary optical correction via spectacles (occasional use of contact lenses if applicable) or agreement to wear spectacles for at least 12 hours a day, every day * Enrolled in or a beneficiary of a social security scheme * Signed informed consent to participate in the study by the adult patient or by a person with parental authority for minor patients Exclusion Criteria: * Confirmed syndromic myopia or findings suggestive of syndromic myopia * Obvious strabismus or significant heterophoria * Corrected visual acuity \< 8/10 in at least one eye * A history of eye surgery (excluding eyelid surgery) in at least one eye * Hyperopia or non-myopic astigmatism * Anisometropia, i.e. a marked difference in correction between the two eyes * Advanced retinal disease in at least one eye, such as myopic maculopathy * Specific visual impairments in at least one eye requiring personalised treatments other than conventional corrective lenses * Intolerance to optical corrections (conventional lenses or lenses with peripheral defocus) * Patients subject to legal protection measures * Pregnant or breastfeeding women * Participation in another interventional clinical trial (drug clinical trial)
