Abstract

THE human binocular threshold is more than 10 per cent lower than the monocular one. This finding has been explained on a statistical basis by Pirenne1, who assumed that the two eyes are independent. The extent to which binocular vision lowers the threshold depends on the relation between stimulus and response and on the absolute value of the threshold. The lower the threshold, tho greater is the benefit.
