Eye-Related Pain Induced by Visually Demanding Computer Work

Abstract

Eyestrain during visually demanding computer work is related to the orbicularis oculi muscle. Muscle pain development during demanding, low-force exercise is associated with increased muscle blood flow, possible secondary to different muscle activity pattern, and/or increased mental stress level in subjects experiencing pain compared with subjects with minimal pain.

Computer‐related visual symptoms in office workers

“…Interestingly, a recent paper has shown significant changes in both blood flow and muscle load in the orbicularis oculi muscle following demanding computer work. This may provide an objective method of quantifying computer related visual symptoms 22 …”

Reliability of Muscle Blood Flow Measurements in Orbicularis Oculi

“…5 Near-infrared light (810 nm) from a light-emitting diode (LED) was directed toward the skin, absorbed and scattered in the underlying tissue. 5 Near-infrared light (810 nm) from a light-emitting diode (LED) was directed toward the skin, absorbed and scattered in the underlying tissue.…”

Effectiveness of a participatory eye care program in reducing eye strain among staff computer users in Thailand

“…In addition, there were significant positive correlations between eye-related tiredness and orbicularis oculi muscle load and eye-related pain and muscle blood flow. Muscle pain development during intentional short-term interventions such as eye exercises can relieve strain on the eyes and also refresh the mind, reflected by improvement in the visual reaction time 14,15. Therefore, sufficient blinking and performing eye exercise may help relieve dryness and tension accumulated in the muscles of the eye.…”
