According to the saying, we had better not make our eyes stare at the light directly. However, in fact, it will depend on the source and intensity of the light. That is to say, if you stare at the lamp, it will produce no long-term ill effect except the eye strain. When you make your eyes have a rest, the strain will go away immediately. Of course, if you stare at some other lights those are not strong; your eyes will not get hurt. On the other hand, if you make your eyes stare at the strong light, such as staring at the sun, then your retina of your eyes will get hurt. If you make the pose for long time, there are more possibilities that your eyes are getting nearsighted or your nearsighted will get worse. What’s worse, if you often make your eyes stare at the sun, at last your eyes will mat get blind. You should notice.
