Article Snippet: Binocular vision in older people with adventitious visual impairment: sometimes one eye is better than two Faubert and Overbury , A between‐within repeated measures design, Canada , N = 49 (AMD) , 79.2 ± 9.2 , Visual acuity Spatial contrast sensitivity , Spatial sine wave gratings generated using Nicolet Optronics 2000 contrast measurement system. Six spatial frequencies were tested: 0.17, 0.33, 1.0, 2.01, 3.81, and 7.63 cycles per degree of visual angle , Best monocular acuity was equal to binocular acuity 55% (27) showed summation/suppression (binocular contrast sensitivity function greater or equal to best monocular contrast sensitivity); 45% (22) showed binocular inhibition For binocular inhibition group, there was a binocular disadvantage for the medium to lower spatial frequencies (2 nd , 3 rd and 4 th spatial frequencies).
