The Health and Safety Executive have on their web site a wide range of guidance. Here is a link to their document containing their guidance on the use of Visual Display Units (VDU’s), computer monitors and screens to the rest of us.
OK, so we all do it… those days where you spend the entire day sat at your desk staring at that rectangular glare that seems to get brighter and more intense as the hours tick on.
We’ve already advised you to take screen breaks. It might sound obvious, but this means actually moving away from the screen and not looking at anything with an electrical plug attached to it for at least five minutes every hour. When you work at a computer, your eyes are fixed in one position for extended periods of time. Think about the last time you blinked whilst reading this! It’s amazing our eye balls don’t look like the parched sands of the Sahara. Dried out and tired eyes lead to headaches, and so does dehydration.
In addition to screen breaks, make sure you’re drinking plenty of fluids whilst at work. Drinking plenty seems to me to be the simplest preventative measure against screen fatigue. I regret the days when I’ve forgotten to bring in my bottles of water, as come 2pm, I get sluggish and that headache brews – unlike the cup of tea I should have made myself earlier.
Finally, ensure that you’re working in a suitably lit environment. Don’t have the glare of the sun directly behind your monitor as you’re exposing your eyes to too many sources of light (different intensities and colours of light). Use blinds to block direct sunlight, use table lamps to illuminate your workspace, and learn how to set the brightness of your monitor to suit both the environment you work in and to make it comfortable on your eyes.
