Do you suffer from headaches, blurred vision, dry or scratchy eyes or even neck or shoulder pain? You could be suffering from eye strain caused by prolonged computer use.
If you spend long hours in front of the computer screen, try these helpful tips to reduce eye strain:
1. Adjust chair height so computer screen is slightly below eye level.
2. Ensure the background lighting is adequate – it should be brighter than the screen.
3. Contact lens wearers may be more comfortable wearing glasses when working at the computer.
4. Position yourself so that you face into open space beyond the screen, not facing a wall.
5. Computer screens attract dust - clean yours regularly
6. Take a ten minute break every couple of hours.
7. Glance away from the screen from time to time, focus on distant objects or look out of the window.
8. Adjust the size of too small text so you don't have to squint. In Internet Explorer, go to View > Text Zoom on the menu bar.
9. Use an eye lubricant if necessary to reduce dryness.
10. Combat glare and reflections with curtains, blinds or a special anti-glare screen.
