alright, dig this-
night vision and infrared imaging could work, but it would be very expensive to do so. although the eyeclops night vision goggles are very cheap, the range for them is only about 50 feet. If you look at the design, it is obvious that those goggles are toys. Real night vision costs at least $150, and perform far better. The problem is not only the quality of the optics, though; it is also a question of proper mounting and use. Adapting a mount onto the helmet can be a tricky proposition, and you also have to worry about eye relief. If you don't set the distance from your eye to the viewfinder correctly, you won't be able to see the image. The complication is the lens- it may block the night vision device, causing improper eye relief (since most night vision goggles have an inch or so of eye relief). Now, there is a way to adapt night vision into the helmet, but it's expensive, unforgiving, and a real pain to explain all the steps and materials necessary.
