小心！智慧型手機會讓你失明 Watch Out! Your Smartphone Can Make You Go Blind
A Canadian teenager recently lost her sight after several hours of watching Netflix on her smartphone, and is still not quite back to 20/20 vision after three months of wearing corrective eyeglasses. It may be rare for such symptoms to last so long. Doctors say, however, that the number of cases of poor vision is increasing rapidly, especially among young gadgetusers. What was once mainly a health issue of the aged is now becoming common even among the very young as they spend ever more of their time looking at tiny screens.
The problem, doctors say, is that small print and pictures viewed up close force the eye's muscle to bend more than it should in order to focus. This tires the muscle, often resulting in partial loss of vision by the end of the day.
Happily, common sense is enough to avoid serious eye damage from smartphones. Spending less time on your favorite gadget, and letting your eyes rest before using it again, should make for a safe experience online. So give your eyes a break!
