Síndrome visual informático: manejo actual basado en la evidencia

The set of ocular discomforts associated with the use of screens is called Computer Visual Syndrome (CVS), and it is an increasingly frequent reason for consultation in clinical practice. The etiopathogenesis of CVS is multifactorial, so the use of different medications, supplements, filters, and devices to improve symptoms has been studied.

The use of screens produces an alteration of the ocular surface that increases the risk of presenting dry eye. On the one hand, among the studies carried out in this regard, the supplementation with omega-3 fatty acids, the use of artificial tears and mucin secretagogues have shown a statistically significant benefit in improving symptoms.

On the other hand, there is no scientific evidence to support the use of blue light filter lenses and despite the fact that berry extracts could produce an improvement in the symptoms of dry eye and visual fatigue, there is still a lack of consistent scientific evidence that demonstrates their benefit.

Lastly, taking periodic breaks, using proper body posture and avoiding long periods of screen use is recommended, the distance and orientation of the screen being relevant.

The objective of this article is to evaluate the scientific evidence that exists in this regard associated with CVS.
