Have you heard of 20-20-2 rules? More and more digital lifestyles are likely to relax. The 20-20-2 rules are designed to do exactly.
According to recent data, people around the world see the screen connected to the Internet and spend about 6 and a half hours every day. Generation Z occupies a notch with an average of 8 hours and twin for five hours and a half every day.
It is not easy for the eye.
Globally, over the last 20 years, especially myopia or myopia, myopia and myopia have increased sharply. Myopia or myopia myopia is a state where distant objects look blurry. There are several factors that can rise rapidly when the prevalence of myopia increases due to digital lifestyle.
- It has been extended nearby: The extended use of the screen in activities such as reading, game or work can increase the risk of myopia or exacerbate progress. The eyes remain in a long -term focal state, which can contribute to the axial kidney (physical change associated with myopia).
- Outdoor time decrease: Studies show that when the time is reduced outdoors, the risk of muscular development increases. The ability to concentrate on distant objects from natural light and outdoors is a protective factor.
- Screen distance: Holding a screen too close to the eye (less than 30-40 cm) can increase tension and increase the risk of developing or worsening myopia.
- Lack of rest: Continuous screen use without regular breaks increases the risk of tension in the eye.
- Posture and lighting: If the posture is not good during the use of the screen and the lighting is inappropriate, it can indirectly contribute to visual discomfort and tension, which can exacerbate myopia progression.
According to the World Economic Forum, the global prevalence of myopia is expected to rise to 50%of the world’s population by 2050, as partially increasing nearby work and screen exposure. In another study reported by Guardian, nearly four -quarter children spend less than an hour of external and about 20%regularly. In terms of this, children reduce their time outdoors than prisoners, as mandatory by the UN guidelines, “every day, who gets an appropriate one -hour exercise outdoors”. What can you do to deal with this problem? That’s where 20-20-2 rules appear.
20-20-2 What is the rules?
This simple rules can create a world of eye health, especially children.
one, After working nearly 20 minutes, the children should look at the object from a distance for more than 20 seconds.. Studies show that children should avoid distances of less than 20 minutes (30 cm) for 20 minutes.
Second, they also have to do it It is intermittently intermittently for at least 2 hours a day. Especially in childhood, outdoor light exposure is important because it can cause the release of retinal dopamine, slowing down and preventing myopia. Your students are also contracting outdoors, which reduces your myopia stimuli, with less depth and image blurring.
The other thing is to ensure the appropriate screen ergonomics when using a smartphone. Keep your arm length on the device screen. Keep your cell phone downward. To reduce glare and contrast on the screen, make sure the room is not good. To talk about glare, invest in a blue light filter for your phone (For Fairphone 5) Reduce the tension of the eye. Set the screen time limit for the age of children and make sure you spend more time outdoors every day. What is your age? WHO is recommended for screen time until at least 3 years of age. After that, children should not look at the screen for more than an hour a day.
Along with the New Year, it is a perfect time to use 20-20-2 rules in life. You will see your own difference. Let’s make 2025 for better screen movements.
