About working with VDU's and Computers
to computer screens can cause eyestrain, which in turn can cause Headaches,
Nausea and Dizziness.
Here are a few
simple precautions which can help protect you from eyestrain:
- Make Sure Lighting
is adequate. i.e. If natural Lighting feels insufficient, be
sure to have good ambient lighting from Above and slightly behind
the Monitor, being sure to reduce the amount of glare and any
reflections on the screen as much as possible.
- Use a filter on
the Screen, not only does this improve contrast, but it also
helps rude glare from the monitor.
- Take Regular breaks.
If you have looking at a screen for more than 45 minutes, you
should get up and take a break. Go for a cup of tea or coffee.
This is good practice, as it gives your eyes a chance to focus
on other things, allowing the muscles inside to stretch and
- Have regular Sight
tests, as occasionally ( especially people over 40) your normal
distance or reading spectacles can be to strong or to weak,
and a pair of intermediate spectacles may help take some of
the work away from your eye muscles.
With an increasing
number of people working with computers these days, opticians and doctors
see far more people who are suffering from eyestrain and many people do
not associate it with their work.
If you have not
had an eye examination, and you work with computers or displays of any
kind, then we highly recommend that you get your eyes tested as soon as
In the UK, your
employer is obliged to pay for a sight exam if you spend more than three
hours a day using a computer or display, and if spectacles are needed
for VDU or Computer work, then the company has to pay. We recommend that
you talk to the Health and Safety Representative at your place of work.
Newer screens help reduce
problems by having a higher refresh rate, this means the image is projected
onto the screen at a higher frequency than was the case some years ago.
Today the refresh rate of a modern monitor is between 70hz and 120hz
( a big improvement over the older models which used to project between
30 and 50 hz).
LCD screens may help too,
as these screens do not use the same raster technology which causes
a normal CRT (Cathode Ray Tube) Screen to flicker and cause problems.
Here is a quick link to Dixons
website, where you can find out more about CRT and LED technology.
