Abstract

Background:

Comfortable working at near and intermediate tasks depend on the efficiency as well as coordination of accommodation and vergence systems. At present, the need for near and intermediate visual tasks has been dramatically increased, requiring prolonged computer- and gazette-related works. It demands excessive working of the extraocular and ciliary muscles. It may cause eye fatigue and other associated asthenopic symptoms. Globally, eye fatigue is one of the most commonly reported conditions in nonpresbyopic population with asthenopic symptoms. It is necessary to get relief from eye fatigue for better near and intermediate tasks.

Materials and Methods:

Thirty-two undergraduate optometry students who were symptomatic based on a validated eye fatigue questionnaire were included after a baseline comprehensive eye examination. Based on the eye fatigue symptoms score, they were equally assigned to a control group and an exercise group with sixteen participants in each. The exercise group performed yoga ocular exercises for up to 6 weeks after which the eye fatigue symptoms were reassessed in both groups.

Results:

In the exercise group, there was a statistically significant reduction in eye fatigue scores (P = 0.003), whereas the eye fatigue scores showed significant increment in the control group after 6 weeks (P = 0.044).

Conclusions:

Yoga ocular exercises reduce the eye fatigue symptoms score by increasing the efficiency of extraocular muscles. Hence, it could be considered as a therapeutic and nonpharmacologic intervention for reducing the eye fatigue and associated asthenopic symptoms.
