N2 - Purpose: To report a case in which the axial length (AL) shortened and the choroid thickened due to the use of violet light-transmitting eyeglasses. Observations: A 4-year-old boy with high myopia was referred to Keio University Hospital. He was prescribed standard eyeglasses. Six months after the first visit, his best-corrected visual acuities were 1.2 and 0.4 in the right and left eyes, respectively, with the standard eyeglasses, and he was diagnosed with anisometropic amblyopia. The right eye then was patched for 6 hours daily during the daytime. Because of the availability of violet light-transmitting eyeglasses, we changed the eyeglasses and instructed his parents to have him engage in outdoor activities for over 2 hours daily to be exposed to sufficient violet light. As a result, the violet light entered his left eye and minimal violet light entered his right eye. The changes in the ALs, choroidal thicknesses, and cycloplegic objective refractions in the right and left eyes during 2 years of wearing violet light-transmitting eyeglasses were +0.85 and −0.20 mm, +4.9 and + 115.7 μm, and −1.02 and + 1.88 D, respectively. Conclusions and importance: We successfully described a case in which the myopia improved, the AL shortened, and the choroid thickened after using violet light-transmitting eyeglasses.
