Abstract:
Objective:To investigate the impact of age and gender on kinetic visual acuity (KVA) and static visual acuity (SVA) in school children accepting physical activities. Methods:From May, 2018 to September, 2019, 1465 school children from various schools of Suzhou City were measured SVA and KVA with standard logarithmic visual chart and KVA detector. Results:KVA increased with age as six to nine years old, and decreased as eleven to 14. KVA was better in boys than in girls (t = 5.147, P < 0.001). SVA decreased with age as six to eight years old, fluctuated as eight to eleven, and decreased as eleven to 14, especially for girls. SVA was also better in boys than in girls (t = 3.692, P < 0.001). The prevalence of myopia increased with age as six to eight years old, and increased more significantly as eleven to 14. There was a low positive correlation between age and KVA (r = 0.046, P < 0.05), and a moderate negative correlation between age and SVA (r = -0.364, P < 0.05). KVA was positively correlated with SVA (r = 0.409, P < 0.05). Age, gender, KVA, right SVA and left SVA were the factors related with SVA. Conclusion:Vision is better in school boys than in girls. There is positive correlation between age and KVA. It is necessary to develop physical exercise according to age and gender to improve vision development, especially at the sensitive stage of visual function.
