Study name	Progressive myopia treatment evaluation for NaturalVue multifocal contact lens trial (PROTECT)
Methods	Randomised parallel‐group design
Participants	Inclusion criteria: aged 7 to < 13 (inclusive), SER error between −0.75 and −5.00 D, astigmatism ≤ −0.75 D, anisometropia < 1.00 D Exclusion criteria: previously worn or currently wears rigid or gas‐permeable contact lenses, including OK lenses, appears to exhibit poor personal hygiene, that, in the investigator's opinion, might prevent safe contact lens wear, current or prior use of BFs, PALs, atropine, pirenzepine, MF or specialised contact lenses, or any other myopia control treatment
Interventions	Intervention: MF contact lenses Comparator intervention: single vision contact lenses
Outcomes	Primary outcome: change in refractive error from baseline Secondary outcome: change in AL from baseline Maximum follow up: 36 months
Starting date	December 2021 Estimated end date: August 2025
