enhances contrasts and prevent the
entry of blue light, which causes the
most discomfort.
•
Personalised adaptation of contact
lenses in case that it is necessary to
correct a refracting defect such as
nearsightedness, farsightedness, as-
tigmatism, or eyestrain.
•
And lastly, follow simple visual ergo-
nomic rules that enable us to improve
our eyesight and, accordingly, our job
performance:
o
Keep a correct distance from the com-
puter, between 50 and 60 cm.
o
Place the computer screen in such a
way that our eyes are aligned with the
top border so that our eyesight looks
downwards, a more ergonomic posi-
tion which also allows our eyelids to
keep our eyes more lubricated.
o
Avoid reflections on the screen and
this way, our brain will not have to eli-
minate the reflected image and we will
save time.
o
Avoid drafts on our eyes and blink fre-
quently to improve the lubrication of
the ocular surface.
o
When we work at a close distance,
it is recommended that we cover
our eyes every 90 minutes with our
hands, trying to visualise with our
eyes closed that we are, for example,
in a theatre and that the curtain goes
down slowly, this way our brain will
perceive darkness and our eye focus
will relax.
o
Washing our eyes with cold water or
with any relaxing solution when we
start to notice symptoms fatigue.
It is necessary to go for an eye check-up
once a year and, of course, as soon as we
notice any of the above-mentioned symp-
toms. The optometrist is the one responsi-
ble for checking the health of our eyes and
the professional who will determine if it is
necessary to use eyeglasses, contact len-
ses, if vision therapy is necessary and will
also explain the vision hygiene rules that
we should take into account to improve
the performance of our eyesight.
