Abstract: The purpose of this measurement is to study the distribution of static depth DL and the interrelation of stereoscopic vision and depth DL among.Chinese male young people. Active depth DL determining apparatus (controlled by electrical means)and adjusting method were used. 1293 young people, aged 18 to 25, wereexamined on seven opthalmological tests. It is found that 1159 Ss were nor-mal; 134 abnormal (including 51 abnormal stereoscopic vision patients). The results showed that the mean of the static depth DL of 1159normal Ss is 2.95 sec(arc) (SD 1.79 sec(arc))and the distribution range is0.45-5 45 sec (arc). The meam of the static depth DL of the abnormal subjects is biggerthan that of the normal. The difference between these two means is verynotable.
