This study is to investigate the safety and efficacy of novel eyeglasses that emit VL from the frames. This is a double-masked, randomized, pilot clinical trial conducted in a clinic in Japan. Forty-three children with myopia were enrolled. Participants were randomly assigned to two groups, wearing VL-emitting eyeglass frames (VLf) that emitted VL of 310 \u03bcW\/cm2 (VLf group, n = 22) or pseudo-placebo eyeglass frames with a minimal emission of VL (&lt;10 \u03bcW\/cm2) (control group, n = 21). The exposure time was 3 h per day. The primary outcomes were visual acuity, tear film break-up time, corneal endothelial cell density, and the slit-lamp\/fundus examinations. The secondary outcome was the 6-month changes in the axial lengths and cycloplegic refractions. Forty-one (95%) participants were included; twenty-one in the VLf group and twenty in the control group. No significant differences were seen in any safety evaluation. Significant changes were seen in axial elongation, choroidal thickness, and cycloplegic refractions in the subgroup analysis of 8- to 10-year-old children (p &lt; 0.05), but otherwise no significant differences were seen. The VLf showed short-term safety and effectiveness against myopia progression.<\/jats:p>","DOI":"10.3390\/jcm11206000","type":"journal-article","created":{"date-parts":[[2022,10,11]],"date-time":"2022-10-11T22:18:13Z","timestamp":1665526693000},"page":"6000","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":50,"title":["Short-Term
