Dry Eye and Computer Screens

At the Dry Eye Centre we have been astounded by the number of working-age patients that we see. Until recently dry eye in this group was uncommon. In our modern world many of us spend most of our day in front of a computer screen or using tablets or mobile phones. When we perform this type of activity our blink rate drops significantly as does the quality of the blink (often it stops being complete). One explanation is that when we concentrate it is similar to when we used to hunt...and if you blink when you are hunting you lose the prey.

Many of our patients report that when they go on holiday their symptoms often improve, and studies have shown that increased computer use can lead to Dry Eye. Heavily concentrating on a computer, mobile phone or tv screen has been shown to significantly reduce your normal rate of blinking.

Blinking performs two very important functions. First, it replenishes the tear layer across the eye and secondly it squeezes the Meibomian glands that release the lipid layer of the tears that stops the tears from evaporating. Once we stop blinking properly, the Meibomian glands can start to become blocked by the oil that is not being released as it should. This leads to a vicious cycle which eventually gives the symptoms of dry eye.

Once the glands are blocked it is possible to use Intense Pulsed Light therapy to unblock them and then to institute blinking exercises to stop the problem occurring again. 

If you think you are suffering from dry eye due to screen use, please come see us for an assessment. We can treat you before things become chronic and recommend therapies and exercises for you to do to keep your Dry Eye at bay.
