The study by Fedtke et al1 demonstrated significant decreases in axial elongation and refractive progression through dynamic optical signals (weekly alternating spectacle films), while maintaining good visual performance, offering an innovative strategy for myopia management. However, based on clinical experience, we would like to discuss 2 key details that may potentially affect long-term adherence: variability in axial length measurement devices across centers and possible short-term visual discomfort during the weekly glasses-switching protocol.
