To correlate between eye complaints of computer users and reduced blinking rate. This study was carried on 20 subjects .all were computer complaining of one or more symptom of computer vision syndrome. Rate of blinking was calculated using digital web camera during work and during casual conversation. Tear break up time and Schirmer`s test was done for all patients during work and at rest. Marked reduction in blinking rate/min from 16.5 to 4.8. Mean tear break up time changes during work was 10.85sec and at rest was 11.2 sec the mean Schirrner's test was 13.5mm during work and 12.9 at rest. Blinking rate is markedly reduced during computer using giving an interpretation for the computer vision syndrome complaints
