根据2025年12月的一项研究,每日屏幕时间超过3小时的儿童在10岁之前发育近视的可能性为两倍。 Kids with over 3 hours of daily screen time are twice as likely to develop nearsightedness by age 10, according to a December 2025 study.

2025年12月发布的一项新研究发现,每天花在屏幕上三个多小时的儿童10岁前发育近视的可能性是那些使用屏幕有限的儿童的两倍。 A new study released in December 2025 finds that children who spend more than three hours daily on screens are twice as likely to develop myopia by age 10 compared to those with limited screen use. 研究人员将这种上升归因于长期近工接触和室外活动减少,这有助于调节眼睛发育。 Researchers attribute the rise to prolonged near-work exposure and reduced outdoor activity, which helps regulate eye development. 美国儿科学会建议,2至5岁儿童每天的检查时间不超过一小时,年龄较大的儿童在更长的课时持续休息。 The American Academy of Pediatrics recommends no more than one hour of screen time per day for children aged 2 to 5 and consistent breaks during longer sessions for older kids.
