ATN Viper Night Vision Goggle: Customer Reviews & Product Details

There is no way you can keep one eyed closed during the entire time you'd be wearing this; when I initially did a search on Amazon it was for "goggles," not a monocular, so the title is misleading. And having both eyes open while using it isn't an option as what you see out of each eye is quite different. However, ours was defective so this is really a moot point: Regardless of which position the on/off switch is in, the device stays on as long as the battery is installed. So quality-control is obviously an issue in at least a third of cases with this device (given that the other two reviews were both positive).

My son loves this product, he's barely taken it off since we got it a month ago! We did notice that it gives slight tunnel vision, and he does regularly bump into walls, but as he's only 2 1/2 that is to be expected!
These are great, I think everyone should have a pair, and then no one needs to be afraid of the dark! And we save on energy because we don't need lights (as often) mind you, you go through a lot of batteries!!!

This is one of the best investments ive made in a while.
Perfect for airsoft, and for camping, and for hunting, and for everything involving darkness.
Not the best image, but for the price...... i didnt expect more than this.
It really is much better than i imagined..... installation was really easy.
This is perfect for my needs.
