One of the main causes of high myopia rate is that many of us do not know or do not reinforce the importance of good reading habits.
Make sure your reading posture, and sit with your back straight, your neck and shoulder muscle should be relaxed. You may need to adjust your table and chair for better posture.
If you are choosing reading materials for your pre-school children, choose one with large prints and with lots of colourful pictures. Studies show that reading plain black and white text would worsen your myopia in pre-school children.
If you still find the lighting in your room not bright enough, you can use a reading light to supplement room lighting. When the lighting is dim, there is a tendency to hold the book too close to the eyes and therefore aggravating myopia. The reading lamp should be positioned close with its light shining from the side. Leaving the room lighting on would help to reduce any reflected glare by the reading lamp.
Fit an anti-glare screen on your monitor. If you have to refer frequently to a document, use a document holder and position it at the same distance and level as you eyes. Maintain a distance of at least 50m between your eyes and the computer screen. This is slightly more than the normal reading distance. The gaze should be directed down. Sit up straight. Do not slouch or crane your neck. Keep the neck and shoulders muscles relaxed. Have the centre of the monitor positioned below your eye label by 15 to 20cm.
Playing computer games (as with handheld video games) are particularly strenuous and playing time should be limited to 30 minute session.
We have all heard about the evil effects of cigarette smoking on our lungs and heart, but there has been little mention of the adverse effects of smoking on vision.
