You have to wonder whether this EMF glass stuff is safely put so close to sensitive areas of the brain such as the fight / flight zone. Who is really gambling on the safety of novel technology here?
Possibly we won't know for a dozen or more years by which time the technology will be seen for what it is, as will the unfortunate side effects.
I keep wondering about that man who developed cancer near his top left shirt pocket where he regularly put his cell phone AND near the point on his waist where he hung his cell phone. Penetration of six inches from the eyes and you hit the amygdala, so I wonder what crazies we will see shooting up the streets in about a dozen years time.
Just thoughts, of course, no facts, just concerns from what any one can read from the science journals.
I would encourage you to read such warnings and take them very seriously.
