在给中学生测量眼球屈光度时,先用视力表测视力,以后用双星明眼水点眼,然后用检影法测量眼球的远点距离,再用检眼镜片矫正,效果很好。 无锡市第六制药厂生产的0.25％的托品酰胺眼水,仅需点眼一次即可满足检影需要,对青少年学习影响不大,可以诊断假性近视,对预防青少年近视眼病有意义。扩瞳检影法测量屈光度很准确,尤其散光眼,减少了主观盲目性,为大规模验光提供了便利。 In measuring the refraction of eyeballs for middle school students, first with the visual acuity chart to measure vision, later with double star Mingyan water eye, and then use retinoscopy to measure the distance of the far point of the eye, and then ophthalmic lens correction, the effect is very good. Wuxi sixth pharmaceutical production of 0.25% tropicamide eye water, eye contact only once can meet the needs of retinoscopy, little effect on young people can diagnose pseudo-myopia, prevention of juvenile myopia is meaningful. Pupil retinoscopy measurement of refractive error is very accurate, especially astigmatism, reducing subjective blindness, providing convenience for large-scale optometry.
