I'm wondering what the long term effects of eye exposure to IR are. From the little I've read online (e.g., http://www.extremecctv.com/Infrared/safety_paper.cfm; there are other articles elsewhere - do a search), there seems to be legitimate concern.
My thought is wearing sunglasses might not help because sunglasses normally protect at the other end of the spectrum i.e., UV.
Plus, we're staring at the monitor and not really blinking much (given how intense our simulators are) , all the while our eyes are bathed in the warm glow of the track IR.
Those of us who build their own IR transmitters can turn off the IR LEDs from the track IR, leaving those of us who don't know how (or don't want to spend the extra time or money) to leave the IR on.
