My personal experience in maintaining vision: First, maintain a healthy weight and exercise regularly. Obese people are at greater risk of diabetes and high blood pressure, which are extremely harmful to eye health. Second, exercise outdoors regularly, especially in the morning sun, which is extremely beneficial for maintaining vision. Third, avoid reading for extended periods. You can get up every now and then to practice standing against a wall, or practice Tai Chi for a few minutes, which combines standing with standing. As long as you practice the correct posture and are diligent with yourself, standing has miraculous effects on promoting blood circulation and clearing your eyes. You'll see immediate results after practicing for just three minutes. Practicing Tai Chi often sparks new and creative ideas, making it a skill worth learning. Fourth, if you have myopia, get LASIK surgery after age 25. This technique has been around for over 30 years and is very mature and safe. The key is to maintain healthy habits after surgery to maintain your vision. Wearing glasses can still make various exercises inconvenient, which can subtly reduce your exercise time and hinder the development of healthy habits. Fifth, without these healthy habits, many people begin to experience presbyopia in their early 40s, which can worsen over time and cause various inconveniences. With good habits, these annoyances can be much less severe.
