Fig. 3From: Relationship between age, refractive errors and motor fusion in a normal Chinese adult population: a cross-sectional studyThe relationship between age and SE, divergence and FVR, (A) SE and age, (B) divergence and age, (D) FVR and age. The mean age was 42.1 ± 0.61 years, ranging from 20–59 years. SE, spherical equivalent. FVR: fusional vergence rangeBack to article page
