초록
본 연구는 콘택트렌즈 착용자와 안경 장용자 그리고 정시안의 대비감도를 비교하기 위해 시행되었다. 조사 대상은 만 19-26세로 근시 70안과 정시 30안을 대상으로 시행하였다, 근시안 그룹은 안경장용자 48안과 콘택트렌즈 착용자 22안으로 모두 교정시력이 1.0 이상인 안구를 대상으로 시행하였다. 공간 대비감도는 EyeView
The aim of the present study was to compare the contrast sensitivity of soft contact lens wearers, spectacle wearers or emmetropia. Seventy myopic eyes and thirty emmetropic eyes aged 19 to 26 years were collected. The myopic group included 48 eyes corrected with spectacle lenses and 22 eyes of them corrected with contact lenses, too: all had corrected vision acuity of 20/20 or better. Spatial contrast sensitivity was measured using the OPTEC 6500 contrast sensitivity view-in tester included the EyeView Functional Vision Analysis software at photopic or mesoopic condition. There was no significant difference in contrast sensitivity between spectacle lenses and emmetropes. Myopes corrected with soft contact lenses showed statistical sensitivity losses at 1.5, 12 cycle/degree spatial frequencies. In conclusion, our findings suggest that loss of contrast sensitivity in soft contact lens wearers might be interpreted as evidence for corneal disruption before corneal pathological events occur in contact lens wearers. Contrast sensitivity testing appears to be a useful method for evaluating soft contact lenses.
