Research on the influence of various factors on the treatment of myopia has advanced considerably from what it once was. Previously, it was thought that genetics played a dominant role in the development and progression of myopia. However, recent studies have shown that acquired environmental factors may have a greater impact on myopia treatment than genetic factors. 1. Reading distance. It was found that the reading distance of myopic children is much smaller than that of orthoptic children. During adolescence and childhood, the eye is more adjustable and the eye wall is more extended. Reading distance is too close to the ciliary muscle and extraocular muscles will be under high tension. Over time, myopia will develop or weaken the effect of myopia treatment. 2, prolonged close eye use. This eye habit tends to cause the ciliary muscles to be in a state of long-term tension, resulting in muscle spasm when farsightedness forms a blurred image that eventually develops into myopia, or stops myopia treatment in its tracks. 3, television and video terminals. The impact of prolonged television viewing and computer playing on myopia treatment is intensifying, and survey results show that the average myopic child watches TV (12.78?9.28) h per week, compared to an average of (8.91?5.95) h per week for non-myopic children. 4. Night lighting. In a combined study of existing visual acuity in children aged 2 to 16 years and exposure to light before age 2, it was found that children who slept in a brightly lit room regularly during age 2 had a 48% chance of needing myopia treatment in the future. Children who slept in dark rooms had a 9 percent chance of needing myopia treatment. 5. Lack of outdoor activities. Outdoor activities are not only physical exercise, but also include outdoor games, picnics, walks and other leisure activities.
