Computer Vision Syndrome (CVS)

Friday, September 19, 2003


The effects of oral intake of Black Currant anthocyanosides (BCA) have been found to relieve the eye fatigue, dry eyes and backaches associated with sitting for long hours in front of a computer screen or a video display terminal.The rapid spread of computers and videos display terminals in the home and workplace has led to an increase in ocular and visual problems, including eye discomfort, blurring of distant objects, eyestrain, asthenopia (visual fatigue) and lower back pain.

Subjects in a double blind, placebo-controlled, crossover study were assigned to four groups:

1) Group given placebo
2) Group given 540 mg of BCA
3) Group given 270 mg BCA
4) Group given 50 mg BCA

The result showed a statistically significant improvement in dark adaptation with the larger amount of BCA. It was also shown that oral intake of BCA has the effect of preventing myopic refractory shift after visual tasks on a video display terminal. BCA intake resulted in a significant difference in terms of prevention of fatigue of the eye and low back pain, as shown by means of the study questionnaire.
