Eye protection in spring is the time when the visual environment should be friendly

The visual environment is one of the risk factors for myopia. Families and schools must actively create a friendly visual environment and jointly protect their children’s bright future. Recently, the Beijing CDC WeChat public account issued relevant reminders.

How to create a visually friendly environment for your family?

The first is to provide appropriate tables, chairs and lighting to ensure a suitable reading and writing environment.

Try to prepare adjustable study desks and chairs for children, and regularly adjust the height of desks and chairs according to the height of the child. Appropriate desk and chair heights make it easier for children to maintain correct reading and writing postures when reading and writing, and are less prone to fatigue. In addition to preventing and controlling myopia, it can also treat myopia. Abnormal spinal curvature has a preventive effect.

The study table is placed next to the window. The long axis of the desk is perpendicular to the window. Natural light enters from the side opposite the writing hand to prevent the shadow of the hand from affecting the line of sight when writing. Too strong or too dark light will have adverse effects on the eyes.

Choose a desk lamp with “CCC” certification and place it in front of the opposite side of your writing hand. When children read and write at night, they should use room ceiling lights and table lamps at the same time to ensure sufficient and coordinated lighting on the reading and writing surface and the surrounding environment.

Help and urge children to maintain correct pen holding posture and sitting posture when reading and writing, and achieve “one foot, one inch, one punch”. In particular, the “one foot” distance is very important, but it is easily overlooked.

The second is to choose and use electronic products rationally and create a good screen usage environment.

When online learning is required, provide children with large-screen electronic products such as TVs and desktop computers. For the same screen size, choose electronic products with high screen resolution.

Pay attention to the placement of electronic products to ensure a safe viewing distance. The viewing distance of the TV is not less than 4 times the diagonal distance of the screen, the horizontal viewing distance of the computer is not less than 50cm, and the viewing distance of the mobile phone is not less than 40cm.

Control the time you spend using electronic products. Preschool children should use electronic products as little as possible, and the total non-learning screen time of primary and secondary school students should not exceed 1 hour a day. You can set the time for using electronic products with your children in advance, and use alarm clocks, hourglasses, and timers to remind your children regularly.

Even if the screen is in “eye protection mode”, you should control the time you use electronic products to reduce symptoms such as visual fatigue and dry eyes caused by using your eyes at close range for a long time. Parents are asked to lead by example, try to put down their mobile phones, spend more time with their children, and protect the eyes of the whole family.

The third is to create a good sleeping environment, go to bed early and get up early, and have a regular schedule.

Artificial lighting and the use of electronic products at night can easily cause circadian rhythm disorders and increase the risk of myopia.

Do not place a TV or computer in the child’s bedroom, use light-proof curtains at night, do not turn on a night light when sleeping, and sleep in a dark environment at night.

Help children develop a work and rest schedule and arrange their work and rest reasonably. Go to bed on time during weekends, holidays and school days and have a regular schedule.

 How to create a visually friendly environment in schools?

In accordance with the “Hygienic Requirements for Myopia Prevention and Control of School Supplies for Children and Adolescents” (GB40070-2021), the school provides students with a good lighting and lighting environment to ensure the illumination and uniformity of classroom blackboards and classroom desktops.

Each classroom is equipped with adjustable desks and chairs or 2-3 types of desks and chairs according to the height range of students. Desks and chairs of the same type can be placed in rows. The height of the desks and chairs should be adjusted once every semester, at least every month. Change student seats once.

Create an eye-friendly and eye-protecting atmosphere on campus, or carry out popular science displays on interesting eye-loving and eye-protecting knowledge to subtly cultivate students’ awareness of eye-loving and eye protection; or post eye charts in classrooms to remind students to self-test their vision and pay attention to their personal vision health.

Finally, whether at home or at school, students must learn to alternate between near and far, combine work and rest, and relieve tension and fatigue. Primary and secondary school students should take a 10-minute break after reading, doing homework, or studying using electronic products for 30-40 minutes; preschool children should take a 10-minute break after using their eyes at close range for 15-20 minutes. You can relax your eyes through distant views, eye exercises, outdoor activities, closing your eyes, etc.
