Let’s face it. Whether you use a computer for work or at home (or
both), you’re more than likely spending at least 2 hours at a time
staring at the screen. It’s just the way it is these
days, computers
have brought so much enrichment into our lives as well as increased
productivity. The problem is that the eye was never designed for such
close activity for hours on end and as a result, Computer Vision
Syndrome or Eye Strain has become a very common complaint.
Symptoms of computer vision syndrome include physical fatigue,
decreased productivity, increased number of work errors, headaches and
neck or shoulder pain. You may also experience irritation, dryness,
redness or a burning sensation in the eye as well as blurred or double
vision after computer use.
The good news is that with a few little changes, you can prevent, reduce or relieve computer related eye strain.
1. Have an eye test
Regular eye tests with your optometrist are extremely important for
preventing or treating computer vision syndrome. Your prescription may
have changed over time and updating this may be all that is required to
resolve the symptoms of eyestrain. It is recommended to have an eye test
every year if you spend a lot of time working on the computer.
In addition, your optometrist can discuss various options with you to
address eyestrain such as anti-reflective and blue light blocking
coatings on your spectacles. Your optometrist may also suggest glasses
specifically for computer work. For example, if you wear bifocals or
progressive lenses, you may be tilting your head at an awkward angle
causing muscle aches and eye strain. A different type of lens, such as
an extended focus or occupational lens may be more suitable for you.
2. Relax your eyes
Focusing fatigue is another cause of eye strain and occurs from
constantly focusing on your screen. On a regular basis, look away from
your computer screen and focus on distant objects. Looking at distant
objects relaxes the focusing muscle in the eye, which reduces eye
fatigue. Try doing this for 20 seconds every 20 minutes. Better still,
take a break from the computer. It’s a good excuse to go for a quick
walk or make yourself a cup of tea.
3. Dry eyes and blinking
It sounds simple enough but quite often people are so engrossed in
what is on their screen that they forget to blink. It’s important to
blink often to keep your eyes hydrated. If you still experience dry eye,
your optometrist will be able to suggest eye drops or gels to keep your
eyes hydrated.
4. Check your lighting
Quite often eye strain can be caused by too much or too little
sunlight coming into the window or by the lighting in the room being too
bright or dim. Try the visor test to see if lighting may be a problem.
Look at your monitor and cup your hands over your eyes like a baseball
cap. If your eyes immediately feel better, then you need to change your
lighting. Experiment with brighter or dimmer lighting as well as angles
of lights to determine what feels more comfortable.
5. Reduce glare
An anti-glare screen attached to your monitor can help reduce glare and reflections that cause eye strain.
6. Upgrade your monitor
Most computer users now have LCD screens but on the off chance that
you still have an old style CRT monitor, it’s time for an upgrade. CRT’s
can flicker which will contribute significantly to eye strain. LCD
screens on the other hand, are easier on the eye and usually have an
anti-reflective surface. Choose one with the highest resolution possible
and the larger the screen the better.
7. Play around with your monitor settings
The ability to adjust your settings is there for a reason! Adjusting
your monitor settings can have a big impact on reducing the symptoms of
eye strain and fatigue. Adjust the brightness so that it is the same as
your surroundings and the text size is comfortable to read. If the white
background in this article looks more like a light source than a
background, then it’s too bright.
Black text on a white background is the best combination for the
eyes. Text size can be adjusted on all computers and web browsers so
choose a size which is comfortable for you.
If you are able to adjust your monitors colour temperature, reduce
the amount of blue and favour orange and red. Blue light has been
associated with eye strain as well as macular degeneration.
8. Clean your monitor
Not only will this keep your screen nice and clean, but dust
particles can decrease screen sharpness making the eyes work harder.
9. Modify your workstation
Review the way you are set up at your workstation. If you have access
to someone who is trained at assessing workstations, it’s worth having
them take a look. Check your posture and ensure that your workstation
and chair are at the correct height and that you are sitting at the
right distance. Your monitor should be between 45 to 75 centimetres away
from your face. The top of your monitor should be around eyebrow level
keeping your neck in a natural position.
So there you have it, some very simple tips to reduce computer vision
syndrome. And as always, see your optometrist if you have any concerns
