While encouraging teachers and learners to use computers, we must be conscious of the fact that their excessive use can lead to eye strain. We must have a sensible approach to computer use in order to protect our eyes.
You can do a number of things to prevent eye strain, such as buying a bigger screen, or replacing your old monitor with a flat LCD screen, or buying an anti-glare screen. All of these come at a cost, which you or your school may not be able to afford.
The best thing you can do for your eyes won’t cost you anything: just take short breaks during computer sessions. Sometimes you look so intently at the screen that you hardly blink – and blinking is important since it keeps the eyes moist. You can compensate for this by looking away from the screen from time to time – or even better, get up and walk around in the room, since this is good for your muscles and skeleton too.
It may be necessary to remind learners in a computer room to tear themselves away from the computer screen this from time to time – and don’t forget that you must also do so!
