Multifocal soft contact lenses (MFSCLs) are widely used to control myopia progression in children. However, their optical design may affect visual quality, especially under glare conditions, potentially influencing their daily visual performance.
To evaluate the impact of MFSCLs on shape discrimination threshold (SDT) under glare in myopic children by comparing changes in SDT under glare and non-glare conditions, with both MFSCLs and single vision spectacles.
Thirty-seven myopic children (37 eyes) were enrolled and fitted with both MFSCLs and single vision spectacles for binocular myopia correction. Assessments included uncorrected and corrected visual acuity, corneal curvature, pupil diameter (PD) in a dark environment, and SDT with glare (SDTon) and without glare (SDToff). Measurements of the right eye were analyzed. SDTs were compared between lens types and lighting conditions, and correlations with ocular parameters were evaluated.
All participants achieved optimal MFSCL fit. No significant difference in SDTon or SDToff was observed between MFSCLs and spectacles ( > 0.05). However, SDTs were significantly elevated under glare compared to non-glare conditions ( < 0.001). In the MFSCL group, SDTon was significantly correlated with PD in the dark ( = 0.336, = 0.042), as was the glare-induced SDT change (SDTdiff; = 0.354, = 0.032). In the spectacle group, SDTdiff was significantly associated with spherical equivalent refractive error ( = 0.435, = 0.007). No serious adverse events occurred, and mild corneal staining resolved with appropriate care.
MFSCLs did not significantly worsen SDTs under glare in myopic children compared to spectacles, suggesting they do not exacerbate disability under glare. These findings support the continued clinical use of MFSCLs for myopia management without compromising visual performance under glaring conditions.
多焦点软性接触镜（MFSCL）被广泛用于控制儿童近视进展。然而，其光学设计可能会影响视觉质量，尤其是在眩光条件下，这可能会影响其日常视觉表现。
通过比较佩戴MFSCL和单焦点眼镜时在眩光和非眩光条件下形状辨别阈值（SDT）的变化，评估MFSCL对近视儿童眩光下SDT的影响。
纳入37名近视儿童（37只眼），为其佩戴MFSCL和单焦点眼镜以矫正双眼近视。评估包括未矫正和矫正视力、角膜曲率、暗环境下的瞳孔直径（PD）以及有眩光（SDTon）和无眩光（SDToff）时的SDT。分析右眼的测量结果。比较不同镜片类型和光照条件下的SDT，并评估其与眼部参数的相关性。
所有参与者的MFSCL佩戴情况均达到最佳。MFSCL和眼镜之间的SDTon或SDToff未观察到显著差异（>0.05）。然而，与非眩光条件相比，眩光条件下的SDT显著升高（<0.001）。在MFSCL组中，SDTon与暗环境下的PD显著相关（=0.336，=0.042），眩光引起的SDT变化（SDTdiff）也是如此（=0.354，=0.032）。在眼镜组中，SDTdiff与等效球镜度显著相关（=0.435，=0.007）。未发生严重不良事件，轻度角膜染色经适当护理后消退。
与眼镜相比，MFSCL在近视儿童眩光下并未显著恶化SDT，表明它们不会在眩光下加剧视力障碍。这些发现支持在不影响眩光条件下视觉性能的情况下，继续将MFSCL用于近视管理的临床应用。
