Contrast sensitivity of deaf and hearing children for sine-wave gratings in mesopic conditions / Sensibilidade ao contraste de crianças surdas e ouvintes para grades senoidais em condições mesópicas

The aim of this study was to compare the contrast sensitivity (CSF) of deaf children and hearing children to spatial frequency of 0.25 to 2.0 cpd (cycles per degree of visual angle) at mesopic luminance level (0.7 cd/m2), using the psychophysical forced-choice method. Twenty children (7-12 years old...
