Other than your skin, almost every other part of your body cannot be fully examined without either entering the body (with a scope) or scanning your body with an imaging device (such as a CAT scan, MRI or ultrasound).

This gives your eye doctor the ability to determine most eye problems just by looking in your eye.

So what exactly are NVGs and what is the technology behind them? What other visual expectations do our military troops use to give us the edge in a battle?

Expertly made night vision goggles can spot a target close to 200 years away. NVG use infrared and thermal detection technology to capture the image in the darkest of circumstances. The electronic information that comes...
