Spending more time outside may help slow the progression of short-sightedness.
Although there is no conclusive evidence on how to prevent short-sightedness, numerous studies have indicated the following may well assist in preventing or slowing the progression of short-sightedness in both children and adults.
Increase the amount of time you spend outside each day. The brightness of natural light is thought to limit the rate of progression.
Take regular breaks from close work e.g. look away from your desk for a minute or so to change focus, or change tasks every 30-60 minutes to alter the focusing demands on your vision.
Try to limit additional close work (over and above school or work) to two hours per day. This includes reading, hand held computer games, drawing, homework and computer work.
There has been a role suggested for vitamin D in the control of myopia and although there is currently no significant evidence to support this, we would suggest that you may wish to take vitamin D supplements.
