Longitudinal records obtained from three optometry practices in the central United States were used to assess the effect of bifocal lenses on the rate of childhood myopia progression. Rates in D/year were derived by linear regression for age spans between 6 and 15 years of age. Records were available for 52 persons who wore single vision lenses (SV group) during this entire age span, and 60 persons who wore bifocal lenses (BF group) during the complete period of observation. The mean rates of myopia progression were -0.44 D/year for the SV group, and -0.37 D/year for the BF group (difference not statistically significant). When rates were determined as a function of nearpoint phoria and near binocular cross cylinder net, the BF group had rates of myopia increase which were lower in magnitude than the SV group in children with nearpoint esophoria and of higher cross cylinder net.
从美国中部的三家验光诊所获取的纵向记录，用于评估双焦点镜片对儿童近视进展速度的影响。通过线性回归得出6至15岁年龄段的屈光度/年变化率。在整个该年龄段有52人佩戴单焦点镜片（SV组），60人在整个观察期佩戴双焦点镜片（BF组）。SV组近视进展的平均速度为-0.44 D/年，BF组为-0.37 D/年（差异无统计学意义）。当根据近点隐斜和近用双眼交叉柱镜净度数确定变化率时，在近点内隐斜且交叉柱镜净度数较高的儿童中，BF组近视增加率的幅度低于SV组。
