ABSTRACT
To obtain adequate information of illumination and lens types for visual acuity test of low vision patient, the relation between various illumination and vision was evaluated. Visual acuity for near and effective lens types were examined. Among the 28 patients (of 36 eyes), intensities of illumination were set at 200, 500, 1000 and 2000lux and the lenses of biconvex, aspheric and aplanatic were tested. The best visible range of illumination for the low vision patients was 500-1000lux, with lower power diopter for the same visual acuity and with aspherin and aplantic lenses. Results attained by our study may be applied for appropriate condition of illumiation and type of lens in the low vision care.
