目的:通过规范某动态视力检测与训练仪的操作流程和使用，探讨动态视力与静态视力(SVA)、动态视力与视标运动速度之间的关系。方法:用某动态视力检测与训练仪检测138名双眼裸眼视力均达到1.0及以上健康男性招飞预选对象的SVA、动态视力(包括DVA和KVA)值，并用SPSS软件进行统计学分析。结果:138名被检对象双眼或单眼的SVA值与分别在30、60、100 km/h运动速度下测得的双眼或单眼的KVA、DVA值相比较，SVA均显著高于KVA和DVA，差异均有统计学意义(n P<0.01)；当视标运动速度从30 km/h提高到60、100 km/h，双眼或单眼KVA、DVA值均随视标运动速度提高而下降，且无论单眼或双眼的KVA值在3组间比较差异均有统计学意义(n P<0.01)；视标运动速度在30、60、100 km/h时，双眼KVA、DVA值高于单眼，差异均有统计学意义(n P0.05)。n 结论:该动态视力检测与训练仪性能稳定、良好，海军飞行员选拔过程应当考虑进行动态视力的检测。“,”Objective:To explore the relationships between the dynamic vision and the static vision, and between the dynamic vision and the speed of visual targets through the standardized operation of the dynamic vision testing and training apparatus.Methods:The dynamic vision testing and training apparatus was used to measure the static visual acuity (SVA), kinetic visual acuity (KVA), and dynamic visual acuity (DVA) of 138 healthy male pilot candidates whose binocular uncorrected visual acuity (UCVA) were at least 1.0. The testing results were statistically analyzed by SPSS.Results:The monocular and binocular SVA of the 138 research subjects were significantly higher than the monocular and binocular KVA and DVA measured at the motion speed of 30, 60, and 100 km/h respectively, and the differences were statistically significant (n P<0.01). When the moving speed of the visual target was increased from 30 to 60 and 100 km/h, both monocular and binocular KVA and DVA were decreased, and the differences of KVA at each speed, either monocular or binocular, were statistically significant (n P<0.01). When the moving speed of the visual target was at 30, 60, and 100 km/h, the binocular KVA and DVA were higher than the monocular ones with statistically significant differences (n P0.05).n Conclusion:The dynamic vision testing and training apparatus has a stable and good performance, and therefore the dynamic vision test should be adopted in the navy pilot recruitment.
