• The BLINK2 study demonstrated that the myopia control benefits of multifocal contact lenses in teenagers persist even after discontinuing their use, with eye growth returning to age-expected rates.
• Axial elongation increased slightly after switching to single-vision lenses, but the overall rate of eye growth remained consistent with age-related expectations, indicating no rebound effect.
• Starting myopia control treatment with multifocal lenses at a younger age and continuing until the late teenage years is a promising strategy for durable benefits.
• The high-add multifocal lens group maintained shorter eyes and less myopia compared to the medium-add and single-vision groups, highlighting the long-term efficacy of early intervention.
