In new research published in the British Journal of Ophthalmology, investigators analyzed the short-term effect of different intensities of sunlight exposure on blood-flow perfusion (BFP) after reading. Give me some background first. Previous research has found that increased intensity and duration of sunlight exposure may reduce the risk of developing myopia. Additionally: Altered fundus blood flow is considered to play a role in the pathogenesis of myopia and serves as a predictive indicator for myopia development. To back this up: Clinical studies have demonstrated that myopic patients often exhibit diminished choroidal and retinal BFP, contributing to scleral hypoxia and subsequent myopia progression. Now, talk about the study. Investigators conducted a parallel, randomized controlled trial (RCT) at the China-based Shanghai Eye Disease Prevention and Treatment Center from August to September 2022. Participants selected were randomly assigned to either: Low-illuminance (4k lux...
