Repeated low-level red light exposure may improve myopia among children: Study
Repeated low-level red light exhibited a stronger impact on myopic children compared with premyopic individuals suggests a study published in the British Journal of Ophthalmology.
A study was done to compare the effects of repeated low-level red light (RLRL) treatment on axial length growth and refractive error changes in myopic and premyopic children. Subjects were assigned randomly to four subgroups: myopia-repeated low-level red light group (M-RL), myopia-control group (M-C), premyopia-repeated low-level red light group (PM-RL) and premyopia-control group (PM-C). Subjects in the RLRL group completed a 12-month treatment composed of a 3 min repeated low-level red light treatment session twice daily, with an interval of at least 4 hours, for 7 days per week. Visits were scheduled before and at 1-month, 3-month, 6-month, 9-month and 12-month follow-up after the treatment.
