Relationship between visual acuity and contrast sensitivity in flying cadets
摘要
Abstract
Objective To analyze the relationship between visual acuity and contrast sensitivity (CS) in flying cadets, and to discuss the possibility of applying CS test in pilot selection . Methods Ninety-eight samples who met the inclusion criteria were divided into two groups according to their visual acuity ( distant vision ≥ 1. 0 or 0. 8 ≤ distant vision < 1. 0 ). The contrast sensitivity function (CSF) values of the different groups checked under 4 spatial frequencies(3,6,12 and 18 cpd ) and 3 statuses(photopic, scotopic, scotopic plus glare) were compared. Results There were no significant differences in CSF values between the two groups under different spatial frequency or light conditions (P >0.05). There were significant differences in CSF values between the photopic group and scotopic group under different spatial frequency ( P < 0.05) , but no significant differences in CSF values were found between the scotopic group and scotopic plus glare group (P >0.05). Conclusion Some of the flying cadets may have normal visual acuity and abnormal CSF values , especially under the middle to high spatial frequency. Since the current physical examination standard of pilot selection fails in this aspect, we may select the CSF values at mid -high spatial frequency and under scotopic conditions as an index .关键词
