Pre-myopia refers to a condition in which children have not yet developed myopia but exhibit insufficient hyperopic reserve (≤ +0.75 D). This is particularly relevant for young children aged 6 years and under; if their hyperopic reserve is depleted prematurely and they progress into the pre-myopia stage, the likelihood of developing myopia or even high myopia in the future becomes extremely high. Therefore, this study plans to conduct a parallel-design, open-label, single-center randomized controlled clinical trial to evaluate the efficacy and safety of artificial intelligence-assisted Defocus Incorporated Multiple Segments Triple Enhanced Design (AI-DIMS) spectacle lenses in preventing and controlling myopia in pre-myopic children aged 3 to 6 years.
