Affected by the new coronavirus pneumonia, many schools have delayed opening hours. Therefore, online courses have become the only way for primary and secondary school students to take classes. In this special period, how should students protect their eyes from harm while using the Internet for learning?


The first is the choice of electronic products. When choosing electronic products for online classes, students are better off using large-screen, high-resolution electronics, such as a projector or a larger-screen TV or computer. The larger the screen of an electronic product, the farther the students can be from it during an online lesson, which will cause less damage to the eyes.

Second is the duration of the eye. Elementary school students should not spend more than two and a half hours a day watching electronic products, middle school students or college students should not exceed five hours a day. For students who go online at home, the three “20” principles are worth mentioning, that is, every 20 minutes, watching 20 feet away, and insisting on 20 seconds, this method is more effective in reducing eye fatigue. In addition, sitting upright and doing eye exercises every day are also important to protect your eye health.

Scientific research shows that sunlight plays a very important role in the prevention and control of myopia. It can promote the production of substances such as dopamine, promote the normal development of the human eye, and can delay the occurrence and development of myopia. Therefore, students can exercise moderately on the balcony or near the window when there is sunshine, which also plays an important role in promoting eye health.

If students stare at the screen for a long time and feel their eyes sore, then they can use hot towels to apply heat to their eyes in order to relieve the eye fatigue. In addition, parents can post a home vision chart in the room to measure the child’s vision and prevent their vision loss.
