Objective To investigate the effect of wearing long wavelength filter glasses on refractive development of children's hyperopia. Methods Case control study. Seventeen 5-7 years' old children with high hyperopia from optometry clinic of Eye and ENT Hospital Affiliated to Fudan University were enrolled in this research. The experiment design was self-control between right and left eye, 3 children were lost during two years' period of observation, all the children's hyperopic refraction were more than+6.00 D, cycloplegic by 1%atropine. All the children were required to wear long wavelength filter glasses for 6 hours after waking up, the rest of the time with the conventional glasses. Refraction, axis and red/green match point were tested before the intervention and 3, 6, 12, 18, 24 months, after the intervention. Results After two years' intervention, hyperopia decreased, eye axis increased, the best corrected visual acuity increased both in experimental eyes and control eyes, but there were no statistically significant difference between the two groups at each time point. All children were with normal color vision, compared to the long-wavelength light, the hyperopic eyes were more sensitive to middle-wavelength light, no significant difference was found between two groups, red/green match points were 42.802 ± 1.216 and 42.889 ± 1.560 respectively. After wearing long wavelength filter, red/green match point were significant decreased in the experimental group in 6 months and 12 months time points (6 months: 0.995 ± 0. 543 vs. 0.104 ± 0.143, t=3.04, P=0.005, 12 months:1.096±0.392 vs. 0.17±0.248, t=2.725, P=0.008). The experiment eyes were more sensitive to long-wavelength light than the control eyes. But in later time, there was no significant difference between two groups. Conclusion Wearing long wavelength filter glasses two years has no effect on refractive development on children with high hyperopia, but it can cause short-term chromatic adaptation, making hyperopic eyes more sensitive to the long-wavelength light.%目的：探讨在高度远视眼儿童配戴滤除中短波长色光的红色镜片，对其屈光发育变化的影响。方法自身病例对照研究。选取2010年7至9月复旦大学附属眼耳鼻喉科医院视光中心门诊5～7岁双眼高度远视眼的儿童17例，其中男性9例，女性8例，采用左右眼自身对照，入选儿童为1%阿托品睫状肌麻痹后验光确定双眼屈光度数均>+6.00 D。干预期间要求试验眼每天晨起连续配戴试验眼镜6 h，其余时间配戴常规眼镜。在干预前和干预后3、6、12、18、24个月分别对患儿进行屈光度数、眼轴长度、红绿平衡点等测量，最终失访3例，完成14例。双眼各项指标数据符合正态分布，其差异比较采用配对t检验。结果24个月后试验眼和对照眼的远视度数均有所下降，眼轴增加，最佳矫正视力增加，但两组之间的差异在各时间点均无统计学意义；所有儿童干预前均具有正常的红绿色觉，试验眼和对照眼红绿平衡点分别为42.802±1.216和42.889±1.560，差异无统计学意义；相较于长波长的色光，远视眼球对于中波长的色光较为敏感。配戴红色滤光镜片后，试验眼与对照眼红绿平衡点6个月时分别下降0.995±0.543和0.104±0.143（t=3.04, P=0.005）；12个月时分别下降1.096±0.392和0.170±0.248（t=2.725, P=0.008）；试验眼对长波长色光的敏感性较对照眼增强。但在干预后期，两组间差异无统计学意义。结论配戴滤除中短波长色光的红色镜片24个月对儿童远视眼屈光发育及最佳矫正视力没有影响，但早期出现红绿平衡点显著降低，红色滤光镜片可以引起短期的色觉适应，使得远视眼球对长波长色光敏感度增强。（中华眼科杂志，2017，53：33-38）
