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.
