Virtual reality and health

I love all the new technology coming out, but I am not blind to the possible negative consequences.

1. Smart watches
Do you really want something sending out bluetooth signals glued to your wrist 24/7? Proximity means something and having something right up next to your skin might not be the smart thing to do.
2. virtual reality head mounted displays
Most of these devices have displays which are basically cell phone screens... and the problem is that you put these devices maybe a maximum of an inch from your eyes. Is it really a good idea to have that right up against your eyes? It seeing a LED or OLED screen that close to your eyes good for your eyes? The samsung gear vr really is putting a cellphone right in front of your eyes. Some people think putting a cellphone up to your ear and head isn't a good idea.. how about putting up an inch or so from your eyes?
3. Wireless everything
At what point does something possibly relatively harmless become harmful in large amounts?
