Effect of fixation target on the contrast sensitivity in the foveal and parafoveal area
Vicent Sanchis-Jurado, Sophie Triantaphillidou, Edward Fry +1
Purpose To determine the influence on the contrast sensitivity when the stimulus contains a fixation target in two retinal locations, foveal and parafoveal. Methods Four young adul…
