This article will use an interesting and popular science approach to help you understand the causes and preventive measures of myopia. Let us say goodbye to glasses and protect our bright eyes with love and care!

The “black hand” behind myopia

Staring at the screen for a long time

Staring at the screen for a long time

Imagine that our eyes are like a sophisticated camera that needs to constantly adjust the focus to capture a clear picture. However, when we stare at mobile phone screens, computer screens and other electronic devices for a long time, our eyes need to maintain a close focus for a long time, which will keep the eye's adjustment muscles in a state of tension, just like a rubber band that is stretched all the time, and will lose its elasticity over time. If this state continues, it will cause damage to the eye's adjustment function, which will lead to myopia.

Modern life is fast-paced, and many people like to stay at home, enjoying air conditioning, WiFi and delicious food. However, long-term indoor life will lead to a lack of outdoor activities and natural light exposure for the eyes. Natural light contributes to the normal development of the eyeball and the improvement of the visual system, while the lack of natural light exposure will put the eyes in a sub-healthy state and increase the risk of myopia.

Eye health requires adequate nutritional support. However, modern people's diets often have nutritional imbalances, especially lacking key nutrients such as vitamins and minerals . These nutrients are essential for the normal development of the eyeball and the function of the visual system. If these nutrients are lacking, the structure and function of the eye will be damaged, which will lead to vision problems such as myopia.

Excessive use of the eyes is one of the main causes of myopia. Therefore, we need to arrange the time we use our eyes properly and give our eyes a rest every once in a while. You can use the "20-20-20" rule, which means looking at a place 20 feet (about 6 meters) away for at least 20 seconds every 20 minutes to allow your eyes to fully relax and adjust.

Increase time spent outdoors

Outdoor activities not only help relieve eye fatigue, but also allow the eyes to be exposed to more natural light, which is conducive to the normal development of the eyeball and the improvement of the visual system. It is recommended to do at least two hours of outdoor activities every day to give the eyes sufficient exercise and rest.

Balanced diet and nutritional supplements
