Preventing computer related eyestrain

Continued from last edition

3. Use computer eye glasses: computer eye glasses are special prescription glasses that decrease strain on the eye by narrowing the focus of your eyes to the mid and near ranges.{{more}} They come with special antireflective coatings and may have a mild tint.

4. Increase the size of the fonts on your computer. If you are using a PC, hold down the control key while moving the scroll wheel of your mouse. With a Mac hold down the command key and the + key

Also use the zoom feature on your computer. You can find this in the view menu on a PC. You can zoom the entire screen on a Mac. There are downloadable programmes that can increase the text size.

You can also use the full screen mode in Microsoft Office to work.

5. Watch how you sit as this may cause shoulder and backaches. Use Ergonomic chairs that give good back support.Also adjust the height of the desk or chair so that the middle of the computer screen is about 20 degrees below eye level. The screen should be at a distance of 16-30 inches from the eyes

6. Blink frequently: Usually we blink at a rate of 15 times/min, but when working on a computer, our blink rate is reduced to 5 times /min because we continuously stare at the screen. When blinking is reduced, the eyes may become dry and irritated

7. Also avoid sitting in front of an air vent or air conditioner or facing its draft while working. This dries out the eyes. Using lubricating eye drops can help reduce dryness. Pay special attention to this if you use contact lenses.

When all is said and done, paying attention to these tips can make all the difference. Do not hesitate to ask your eye care practitioner for more tips to prevent eye strain.

Take care of your eyes and happy computing!
