Hi, my question is: Is the infrared sensor you need in order to play on the Wii harmful for eyesight (especially when you are a kid). Because I used to play on a Wii a lot and when I did I watched for a long time at the black sensor bar to point to in order to successfully play the games. Also is Infrared from an IR-camera to see at night bad to look into? I also did that now and then. Thanks in advance for your answer.
