CTOnews.com August 23 news, analysis company Cochrane recently joined Melbourne University and London University, conducted 17 controlled trials, found that the market sales of "anti-blue lens (blue filter lens)" to improve "computer-induced eye fatigue" or "sleep quality" effect is not significant, the results of the paper published in "Cochrane Database of Systematic Reviews," CTOnews.com partners can view here.

It is reported that the research team mainly evaluated the effect of "blue filter lens" on improving visual performance, protecting retina and improving sleep quality compared with "ordinary lens." They analysed data from all relevant randomised controlled trials they could find and conducted 17 trials in six countries. The number of participants in each study ranged from 5 to 156, and the time taken to evaluate lenses ranged from "less than a day to five weeks."

▲ Laura Downie, head of the cochranelibrary study, said that compared with traditional lenses, it is difficult for users to reduce visual fatigue caused by computer use when using anti-blue lenses. Researchers cannot guarantee that these "anti-blue lenses" can improve users 'vision quality, nor can they guarantee that wearing relevant glasses can "improve sleep" and "promote retinal health." Therefore, the research team believes that, People "should be aware of these findings" when deciding whether to buy such blue-light-resistant glasses.

Laura Downie said: "Over the past few years, there has been a heated debate about whether anti-blue lenses have physical value. Studies have shown that patients in many parts of the world wear these lenses regularly, and there is a range of claims on the market about their potential benefits, including 'they can reduce eye fatigue associated with the use of digital devices, improve sleep quality and protect the retina from light', although the evidence for these claims is' not conclusive 'according to available surveys."
