Our vision can
coexist with the new
technologies, although
we must learn how to
adapt it

for a long time looking at a short distance.
Our vision has not evolved at the same rate
as our daily habits. It was not that long ago
that we spent our time gathering and hun-
ting and at that time we needed good vision
for long distances as well as good periphe-
ral vision so that we could be aware of what
was happening in our surroundings , thus
ensuring our survival. Currently, we spend
most of our time in closed environments,
increasingly smaller, working at a close dis-
tance and this leads to several symptoms,
such as irritation, watery and red eyes, the
sense of having sand in our eyes, cloudy
vision at close distances, difficulties for
looking afar after spending too much time
looking at things up close, double vision,
ocular pressure, etc.
Since 80% of the information that we re-
ceive, process and interpret is provided by
our eyesight, we should be aware of the
role that it plays and the impact that this
could have on our working lives. Its impor-
tance is such that, in processes such as re-
ading, 100% of the information is perceived
through our eyes.
We should be aware that vision problems
in relation to our job performance when we
work with computers are problems that can
be avoided and that there are several solu-
tions for addressing these problems.
•
The use of special prescription eye-
glasses with corrective lenses to
reduce fatigue when we work at a
close distance.
•
Vision therapy to improve the perfor-
mance of our vision system, making
it less difficult, for example, to focus
our eyesight.
•
The use of eye-drops to moisten the
ocular surface sine working in front
of a computer screen reduces the
number of times that we blink and
this can produce ocular dryness.
•
The use of selective absorption fil-
ters that reduce fatigue, since it
