A method and apparatus for allowing a user who wears spectacles including at least one lens having a positive magnification factor, to view a distant object through both the lens of the spectacles and a telescop
Control drivers had significantly better visual acuity (logMAR -0.05±0.04) than visually impaired drivers (logMAR 0.69±0.09, P<0.01), even when these drivers used their bioptic telescope (logMAR 0.13±0.04, P<0.01). Log contrast sensitivity was poorer among bioptic drivers (1.51±0.19 vs 1.80...
