Simple Ways To Avoid Computer Vision Syndrome

Updated on November 20, 2014

Computer Vision Syndrome : Be Eye Aware

If you use a computer regularly, there is quite a high chance that you suffer from CVS, that is Computer Vision Syndrome. Ergonomic studies have shown that most computer users have some or all of the eye problems that can develop with prolonged use of computers.

Working with my adult beginner students in their computing class, I make sure to remind them to blink. It's a simple, but effective preventative measure. Viewing a computer screen close-up, and focusing intently on it, can cause you to stare at the screen. After a while, this will reduce the rate at which you blink, leading to dry eyes and eye strain. In turn this can lead on to other eye problems and headaches. Blinking and keeping hydrated are useful tips for us all. In this lens, I offer some additional preventative measures and tips that I hope will help you reduce or prevent CVS symptoms.

Safe Viewing - Allow your eyes to rest

One very simple way to reduce eye strain is to allow the eye muscles to rest. If you focus continually on the computer screen, you can overload the muscles for close vision. The solution is simple, just look away from the screen and focus on something at least 20 feet away. Use the 20-20-20 rule: every 20 minutes, focus on something at least 20 feet away, for 20 seconds. You just have to remember to do it! If you work too intently to remember, you could try using a built-in reminder, such as the EyeDefender freeware rest reminder.

Another useful option is a pair of computer glasses. They have lenses specially designed to reduce the eye strain that can come with prolonged computer use. You should, in any case, have regular eye checks. If you need corrective glasses or contact lenses, wearing them will help to protect your eyes. If you don't need to wear corrective lenses, you could still find computer glasses beneficial and you should certainly consult an eye doctor if you are having any eye problems from computer use.

There are many Designs of Computer Glasses available

Generally, they are not expensive, and could save you years of headaches and eyestrain. I find it surprising how often I have to suggest to adult beginners that they get their vision checked. this is usually because they are hunched up close to the screen, squinting or complaining that they can't read text on the screen. If you have any of these difficulties, please get your eyes checked.... For your own good!

Do You Take Breaks?

I tell my students to take regular breaks when computing. They usually nod wisely... but, I wondered if they do take breaks from computing when they go home.

Tell the truth, do you take regular breaks from your computer?

The Best View

Whether you use a desktop computer or a laptop, there are some issues to bear in mind. For me, the first is size. As a teacher of computing, I believe you should minimise your use of small-screened devices. I have a desktop computer, a laptop, a netbook and an iPad. It's very difficult to work on the netbook - I bought it for emergency use whilst travelling. It was OK for emails and facebook, but I found it hard to write letters or edit photos with such a small screen. The iPad has a slightly larger working screen, but I see this more as a fun, communication toy. It gave the netbook the boot from my travel bag as it is significantly lighter. So, when I work seriously, it has to be the larger-screened desktop or laptop computers.

When I got fed up with the hefty old monitor taking up most of my working space, I upgraded to a flat-screen monitor. I couldn't even give the old monitor away! Not surprising really, as it was so difficult to move around (ouch, my back...). For good computer-health, it should be possible to adjust the position of your monitor to prevent back and neck ache, and cut glare (see below). The prices of LED and LCD flat-screen monitors have reduced significantly in the last few years, and the quality has improved dramatically, so it is now possible to get a sleek, large-screened monitor at a very reasonable price.

Once you have the right monitor, make sure it is adjusted to suit you. It's easy to adjust the brightness of the screen. For a PC, click the start button, select "control panel" from the menu. This will open the control panel window. Select "hardware & sound", and then "display". Here you can adjust screen resolution, screen brightness, and other display settings, such as text size.

Use the best equipment you can

It's not necessarily about spending a lot of money. It's more about considering the size of your work space, the layout of the room, and checking out the consumer reviews available on all good websites.

Do you need to replace your monitor?

Using a good quality monitor can completely change your computing experience! I'm very happy with my Viewsonic monitor.

Keep your distance

Over the years, I have seen a few students who hunch-up close to the computer screen. I usually ask them if they have had their eyes checked recently. If not, I advise that they should. Sitting to close to the screen can aggrevate the issues caused by glare. It can also lead to postural problems, back and neck ache. If you need to wear glasses for computing, please do so - protect your vision!

Your viewing distance should be 18 to 24 inches, looking slightly down at the monitor, elbows at your sides, and your wrists straight. Check yourself now!

And, keep it tidy, unlike the photo... If your workspace is untidy and cluttered, it will be much more difficult to keep on top of your workload and keep up these good health tips.

Laptop trays

I'm not a great believer in slouching on the couch or lying in bed with a laptop. However, if you must do it, you can mitigate some of the issues by using a correctly designed laptop tray. And, that doesn't mean "a cushion"! Laptop trays can also be very useful for preventing the laptop from over-heating. That, I approve of!

Are you sitting comfortably?

Don't forget this important aspect of computer health and safety. You should be able to sit comfortably, at the correct distance, and with your back appropriately supported.

Ergonomically-designed kneeling chairs can help you regain a natural posture and reduce lower back strain. They also sit you in a correct position to allow your diaphragm to move efficiently, which is good for promoting better circulation and breathing.

Myth or Reality?

Are we obsessed with health and safety? Is it all just a scare story? Or is it sensible to take some precautions to protect your eyes?

Do you consider your health while using the computer?

Cut the glare

Glare is one of the main causes of eye strain. A bit like magpies, we have a tendency to like bright, shiny objects, but bright, shiny computer screens are a definite eye-health hazard. There are some simple tips for cutting down glare to protect your eyes.First, make sure that your screen is positioned and adjusted correctly. If you can, place the screen at 90 degrees to your window, but don't sit in a twisted way, as that will just give you a different kind of problem! Anti-glare film on your windows can cut glare and help to maintain a comfortable working temperature in the summer months.

If you work after dark, be careful about the room-lighting. You should diffuse the light on ceiling lamps or desk lamps by using a shade or globe to soften the light. But, don't work in the dark - it's too difficult to see the keyboard, and will also strain your eyes!

There are many screen filters available which can be clipped over or attached to the screen. These filters can cut the glare and reduce eye strain, but also they can protect from static and radiation. Pick a lightweight filter, of the correct size for your screen. Some filters also help with privacy and protection of confidential information, by narrowing the angle for the viewing the screen.

Anti-glare screen filters

Make sure you select a filter that is the correct size for your computer screen!

Reduce Glare In Your Rooms

Of course, it isn't just computer screens that are affected by glare. If you prefer, it is simple enough to fit anti-glare film to your windows. This has the advantage of helping to maintain room temparature during the summer months, and cutting down on harmful radiation. And a bonus: protection of your book covers, photos and other valuable objects from sun-induced fading.

      @Snakesmum: Great tip here... after looking at the screen for a while, look away into the distance to see something in the garden. Really helps to relax the eyes!

      I have my PC close to a window, where I can see my cat in her outside pen, and birds on the birdbath. This helps me to look away from the screen more often. Good tips!
