Myopia can be triggered by congenital hereditary factors, which are unavoidable. However, acquired myopia is mostly caused by bad living habits. Identifying these risk factors enables effective prevention of nearsightedness.

Six Major Causes of High Myopia Incidence

Unhealthy eye usage habits

Watching TV at close range, playing mobile games for extended hours, reading while lying down and other improper eye-straining behaviors easily induce myopia.

Unbalanced and poor diet

Frequent intake of high-calorie junk food, sugary snacks, carbonated drinks and puffed food provides little nutrition and hinders normal eye development.

Excessive exposure to digital devices

While the internet brings convenience, it severely damages children’s eyesight. Prolonged mobile phone use distracts students from study and leads to myopia, dry eye syndrome and other ocular diseases.

Insufficient physical activity and outdoor time

Modern children rarely go outside for sports after classes, and this group faces a much higher risk of developing myopia.

Harmful environmental conditions

Reading in dim light, together with air pollution, noise and haze, all impair visual function.

Chronic sleep deprivation

Staying up late and inadequate sleep accelerate eyesight deterioration. A regular rest schedule with 6 to 8 hours of sleep daily is essential for eye health.

Effective Measures to Prevent Myopia

Stick to eye exercises

Though often overlooked, standardized eye exercises relax eye muscles, boost ocular blood circulation and relieve visual fatigue, slowing the progression of myopia and alleviating discomfort for high myopia sufferers.

Adopt scientific eye-use rules

Heredity accounts for some severe high myopia, yet most cases stem from poor habits: reading or scrolling phones in bed, studying in dim lighting, and overusing screens. Avoid prolonged eye strain to protect vision.

Look into the distance regularly

Taking breaks to gaze far away and stare at the sky relieves mental stress, relaxes ciliary muscles and stabilizes eyesight. Step away from electronic screens as often as possible.

Supplement vitamins adequately

Vitamins protect the optic nerve and reduce myopia risks. Eat plenty of vitamin-rich fruits and vegetables to prevent and ease nearsightedness.

Conclusion

Myopia brings persistent troubles and cannot be completely cured once developed. Therefore, active prevention and timely intervention to slow myopia progression are extremely important.
