With the development of modern technology, people’s lives are increasingly inseparable from electronic products, which has also made vision problems gradually become a topic of general concern. So what behaviors will affect vision? What sports are good for vision? The following will provide you with some useful references by exploring these issues.
Myth 1: Does watching TV affect vision?
Many people think that watching TV will affect vision, but in fact this is not entirely correct. Although staring at the TV screen for a long time will cause a certain burden on the eyes, in comparison, the screens of electronic devices such as mobile phones and tablets are smaller and put more pressure on the eyes. Especially when watching short videos, due to the short content and frequent switching of the video, it is easy to cause eye fatigue, which in turn causes vision problems such as myopia. Therefore, we should try to avoid using electronic devices such as mobile phones and tablets for a long time, especially not in dim environments. At the same time, you can reduce the pressure on your eyes by adjusting the screen brightness, color temperature and other settings.
Myth 2: Is exercise good for vision?
Exercise not only helps to maintain physical health, but also has a positive impact on vision, among which outdoor exercise is particularly important. When exercising outdoors, people can stay away from the interference of electronic products and let their eyes get enough rest and relaxation. At the same time, the ultraviolet rays in the sun help promote the secretion of dopamine in the eyes, thereby inhibiting the growth of the eye axis and preventing the occurrence of myopia. In addition, some specific sports can also help improve vision.
1. Swimming: The visual environment in the water is very different from that on land. Swimming requires the eyes to constantly adjust the changing distance and direction, which can exercise the eye muscles, enhance the eye coordination ability, and improve hyperopia and myopia.
2. Eye movement: Eye movement includes up and down, left and right, squint, tracking objects, etc. Eye movement training can be used to strengthen eye muscles, enhance eye adjustment ability and visual field.
3. Yoga: Yoga exercises help reduce eye pressure and promote eye blood circulation. At the same time, certain yoga positions can also improve myopia and astigmatism.
4. Volleyball: Volleyball requires quick response. The process of chasing and hitting the ball can exercise eye muscles, enhance hand-eye coordination and spatial perception.
5. Squash: Squash requires quick response, predicting direction and distance, and training the coordination and sensitivity of eyes and hands. At the same time, activities in a small venue can also increase eye focus.
Of course, the benefits of exercise for vision are not achieved overnight, and long-term persistence is required to see obvious results. Therefore, we should develop good exercise habits and integrate exercise into daily life.
Myth 3: Pay too much attention to myopia?
When checking their vision, many people only pay attention to whether their myopia has decreased, but in fact, the axial length is more meaningful for reference. Axial length refers to the length of the anterior-posterior axis of the eyeball, which is closely related to myopia. The longer the axial length, the higher the myopia. Therefore, paying attention to the changes in axial length can more accurately understand the condition of vision. Of course, the measurement of axial length requires professional equipment and technology, which is difficult for ordinary people to do in daily life.
But we can infer the trend of axial length changes by observing our vision conditions, eye habits, etc. For example, if you find that your myopia continues to increase, or your eyes often feel fatigue, dryness and other discomforts, it may be a manifestation of the gradual increase in axial length. In this case, we should adjust our eye habits in time, increase the time of outdoor exercise, avoid using electronic devices for a long time, etc. At the same time, you can also consider consulting a professional ophthalmologist for more detailed examination and treatment.
