Introduction: We depend on eyesight more than any other of our senses to maneuver through the space around us. In a fraction of a second, our eyes work with our brain to tell us the size, shape, colour, and texture of an object. Our eyes are body's most highly developed sensory organs. The use of computers and television in the era of information technology has given new heights to the professional success rate and it saves time but on the other hand, it has led to an increase in the number of patients with ocular complaints.

Aims: The objective of the study was to study the effect of eye exercise techniques along with kapalbhati pranayama on Visual Reaction Time (VRT).

Material & methods: Total 60 subjects in an age group of 18-30 were recruited in the study. All the subjects were divided into two equal groups (study group and control group) containing 30 subjects (18 male & 12 female) each. Both the male and female subjects were selected on the basis of their voluntary involvement. Visual reaction time for red and green light was recorded from all 60 subjects before the start of the study. Study group subjects were trained to practice various eye exercise techniques and kapalbhati pranayama for 8 weeks regularly whereas control group were busy with their routine activities. After 8 weeks, visual reaction time was measured for red and green light from all 60 subjects.

Statistical analysis: Data expressed as Mean ± S.D, Student t -test was applied for analysis of data, p value <0.05 is taken as statistically significant.

Results: Statistical analysis of data shows that there is a significant decrease in the visual reaction time for red and green light after intervention in study group (p value <0.05). Whereas there is no significant decrease in VRT in control group (p value >0.05).

Conclusion: The results of our study suggest that simple eye exercises along with pranayama helps in improvement of visual reaction time.
