I must admit that the Eyeclops toy night vision optic looks really cool. I wondered if they worked as advertised since I actually saw the advertisement. Judging from the Amazon reviews, they do.
Yes, the optic is somewhat disorienting. Yes, it's a monocular with a narrow field of view and no depth perception. But guess what? All that is still true even with most current gen military systems. Trust me, I've almost fallen down a flight of stairs while stumbling around in the dark using military training units.
Now I'm not saying that the Eyeclops is equivalent to that military unit. It's a toy that is probably too fragile for a $70 item that you're going to give to a 10 year-old. I'm just saying I wish they'd had these when I was that accident prone 10 year-old.
