Outdoor sports VS indoor eye protection, which way is more conducive to protecting eyesight?


Recently, there has been a heated discussion about the protection of eyesight on the Internet. As the problem of excessive use of eyes and vision decline is widespread nowadays, many people want to improve their eyesight through some methods. So, which way can protect eyes more effectively, outdoor sports or indoor eye care?
When it comes to outdoor activities, some people worry that glaring sunlight might harm their eyes. In fact, sunlight serves as nature's best eye coach. The gentle fluctuations in natural light intensity allow the lens and ciliary muscles to move flexibly. The distant mountains and lush trees seen outdoors help relieve eye fatigue, while fluttering butterflies constantly adjust focus. When you look up at the light spots between leaves, your pupils automatically adjust—these all contribute to exercising eye muscles. More importantly, expansive outdoor views help decompress eyes and achieve complete relaxation. Studies show that 2 hours of daily outdoor activity can effectively prevent myopia. However, precautions are needed during midday when intense sunlight may damage retinal health. It's best to wear sunglasses during this time.
Eye care in indoor environments primarily focuses on light management and maintaining proper eye habits. Avoid reading under harsh light or using your eyes in dimly lit areas – lying down to scroll through your phone after turning off the lights is a bad habit. Keep computer screens at arm's length, ideally about 30cm away. Since most indoor spaces have a maximum viewing distance of five meters, follow the "20-20-20" rule: After 20 minutes of close-up work, take a 20-second break to look at objects 20 feet (6 meters) away. Additionally, eye exercises can be beneficial. During limited time, massage acupoints around your eyes to stimulate and relax eye muscles.
In conclusion, whether it's outdoor activities or indoor eye protection, taking measures will ultimately help safeguard your vision. After all, the key to eye care lies in prevention and maintenance. Generally speaking, these two approaches complement each other and work best when combined. If you can't guarantee time for outdoor activities, make sure to relax your eyes as much as possible!
