230822 研究新发现:防蓝光眼镜可能是"智商税"
▍原文
Blue-light blocking glasses probably don’t do much to reduce eye strain, help keep people alert or improve sleep, according to a meta-analysis looking at 17 studies published Thursday. “There is still further research that needs to be done, but based on what we have, there is likely no advantage to using those glasses to reduce digital eye strain.” said lead author Laura Downie.
