Many people suffer from myopia. A survey has found that people who spend five hours or less a week outdoors have up to a 60 per cent chance of suffering shortsightedness.
Most children spend too much time reading or in front of computers, which damages their eyesight. I think students should look into the distance, for example at a faraway tree, for one or two minutes after reading or using the computer for 30 minutes.
The survey also stressed the importance of outdoor activities, which are good for our eyes and body. It is also important to have regular eye examinations so any problems can be found early.
When I was in kindergarten, we did eye-movement exercises after lunch. I believe children should be taught the importance of looking after their eyes from a young age.
Prevention is better than cure, so protect your eyes now.

Thank you for your letter, Cherrie. Wow, that's an argument for getting away from studying for a while. Many people in Hong Kong wear glasses, and it is true that looking at a fixed spot for a long time can have a bad affect on the eye muscles and lens.
Eye exercises are a great idea and many people say they help. Let's hope Young Post readers make it a habit to give their eyes a break while they cram for all those important exams.
