INTRODUCTION Light as medicine may seem like a new concept, but scientists have known since at least the late 1800s that certain wavelengths of light in prescribed doses can be used to heal the tissue [1,2]. For the eye and vision care community, light is being used as Intense Pulsed Light Therapy (IPL) for dry […]
Effect of Repeated Low-level Red Light on Myopia Prevention Among Children in China With Premyopia
Abstract Importance Myopia is a global concern, but effective prevention measures remain limited. Premyopia is a refractive state in which children are at higher risk of myopia, meriting preventive interventions. Objective To assess the efficacy and safety of a repeated low-level red-light (RLRL) intervention in preventing incident myopia among children with premyopia. Design, Setting, and Participants This was […]
Low-intensity, long-wavelength red light slows the progression of myopia in children: an Eastern China-based cohort
Abstract Purpose To determine the effect of low-intensity, long-wavelength red light therapy (LLRT) on the inhibition of myopia progression in children. Methods A retrospective study was conducted. One hundred and five myopic children (spherical equivalent refractive error [SER] −3.09 ± 1.74 dioptres [D]; mean age, 9.19 ± 2.40 years) who underwent LLRT treatment (power 0.4 mW, wavelength 635 nm) twice per day […]
Investigation of the Efficacy and Safety of 650 nm Low-Level Red Light for Myopia Control in Children: A Randomized Controlled Trial
Abstract Introduction: To evaluate the 6-month efficacy and safety of 650 nm low-level red light (LLRL) for myopia control in children. Methods: This was a single-center, single-masked randomized controlled trial. A total of 224 children aged 6-12 years with spherical equivalent error (SER) of – 6 diopter (D) to – 0.5 D were enrolled, and were randomized […]
Effect of Violet Light-Transmitting Eyeglasses on Axial Elongation in Myopic Children: A Randomized Controlled Trial
Abstract The fact that outdoor light environment is an important suppressive factor against myopia led us to invent violet light-transmitting eyeglasses (VL glasses) which can transmit violet light (VL), 360–400 nm in wavelength, for the suppression of myopia, and can meanwhile block harmful ultraviolet waves from sunlight. The current study is a double-blinded randomized clinical […]

Myopia Control Effect of Repeated Low-Level Red-Light Therapy in Chinese Children: A Randomized, Double-Blind, Controlled Clinical Trial
Abstract Purpose: Repeated low-level red-light (RLRL) therapy is an emerging treatment for myopia control. Nevertheless, previous studies are limited by open-label design. Our study aimed to assess the efficacy and safety of RLRL therapy in controlling myopia progression compared to a sham device with only 10% of the original power. Design: Randomized, double-blind, controlled clinical trial. Participants: A […]
