Along with poor lighting, regular computer use is one of the biggest causes of discomfort for your eyes. Headaches, uncomfortable dryness of the eyes, mental tiredness and a gradual loss of sharp vision throughout the day are all tell-tale signs that prolonged computer use might be contributing to undue strain on your eyesight.
Millions of us rely on computers to do our jobs, and many people unwind after a long day by web-surfing, on social media or instant messaging. Numerous studies have proved that looking at a monitor or phone doesn't damage your eyesight in itself, but like so many things in life, doing it to excess can be unhealthy. The eyes were not intended to stare at a screen for hours on end, so if this is part of your daily life, how can you ease the burden on your eyes?
Firstly, adjust your seating position as you would in a car. Set your monitor and seat so that the centre of the screen is around two feet away and positioned slightly below your natural eye level. Adjust the screen brightness so that it isn't too piercing or dull. If necessary change the standard font size on your computer; bigger text will be easier to read. Don't be tempted to squint in order to see things clearly, since muscle fatigue will almost inevitably follow.
Lighting is a crucial component in avoiding eye strain. If your computer is near a window, could sunshine make it hard to see things clearly? Harsh artificial lighting is another potential problem, especially in the office;full spectrum lighting is much better for you than standard bulbs or striplights, since it gives a more accurate representation of real daylight. It's also considered helpful in reducing seasonal affective disorder.
Other things you can do to reduce eye fatigue include taking a few minutes away from the screen every hour, giving your eyes a chance to focus on more distant objects. When we stare at things, we tend to blink less, but regular blinking helps to prevent the surface of our eyes from drying out. Contact lens users are particularly susceptible to this, although lubricant eye drops can also be used to help restore the tear film layer. Screen filters reduce glare in bright environments, and it's important to keep dust off your monitor - it's much harder to see the screen clearly
through a layer of grime.
If you habitually use a computer screen, legislation obliges your employer to provide and pay for regular eye examinations and to contribute towards any spectacles which may be required specifically for computer use.
