Online published on 21 November, 2019. Abstract Younger populations of this modern age are highly exposed to digital screens of different kinds of electronic gadgets. Continuous exposure to digital screens leads to eye strains/visual fatigue which may impact poor orientation and reduction in efficiency. Aim To assess the visual fatigue among young male and female subjects by using critical flickering fusion frequency (CFFF). Material and Method A total of 60 young healthy adults of age 17–19 years were invited to participate. Of them 30 were males and 30 were females. The CFFF and visual fatigue protocol consists of the subject has to observe flickering light emitting from red LED module. The changes in light flickering were recognized and report by the subjects. The resulting data was statistically analyzed. Results Mean CFFF values for male participants are 45.7 ±23.5 Hertz, female participants is 41.4 ±13.9 Hertz with highly significant p value =0.000. The result of our study appears to be reflecting sex differences in visual fatigue. A statistically significant difference between male and females CFFF data was observed. Conclusion CFFF can be considered to be a non-invasive tool, useful for screening of diseases of the optic nerve and also an effective indicator of visual fatigue. Occurrence of visual fatigue is seems to be more common in young females than young males which may impact their work performance. This might be reduced by proper guidance; simple changes and precautions such as maintain distance between the screens and eye, regular blinking while seeing the devices.
