Do blue light blocking glasses work?

Usually, blue light blocking glasses are yellowish, and this obvious color shift can cause serious visual fatigue. The aggravation of visual fatigue will not control myopia and will accelerate the progression of myopia. The most important thing is that some parents have the misconception that blue light blocking glasses can control myopia. If they allow children to use electronic products without guidance and control, myopia will definitely progress. During online classes, the best way to avoid the blue light damage of electronic products should be to relax their eyes between two classes. You can learn from the 20-20-20 rule recommended by the American Academy of Ophthalmology, which is to look at objects 20 feet away for at least 20 seconds for every 20 minutes. Also, you can take a break of 10-15 minutes between each online class. You can choose to look at the distance, play table tennis at home, or have fun with parent-child interaction. In this way, the tense shoulder and back muscles can be relaxed while the eyes are relaxed and rested. Not only can it prevent and control myopia, but it is also very helpful for improving the efficiency of learning. Teach children to blink their eyes more consciously when watching the electronic screen, and use a warm wet towel to heat the eyes during rest. A humidifier can be used at home to increase the humidity of the surrounding environment. This can effectively prevent dry eyes caused by looking at the electronic screens for a long time.
