YES

It emits Inferred Light the only thing that would be able to see it would be another pair of these or actual Night Vision Goggles. other then that nothing can be seen by the naked eye.

Check batteries are in right and make sure to turn it on, on the back of the battery pack. I had not troubles getting it to work doing these things.

I am not familiar with the gun your describing but the cyclops does distort distance so I would think that targeting a scope would be hard. I have not tried using it with a scope.

i have nerer done airsoft but i do hunt and i don't think you would be able to aim with them on and you can not judge distane very well and i would not try running with them on the veiw screen is on the right side and you can open the left to see without the goggles but there is not a lense over it so you might get hit in the eye but they are fun but after i have them on for about 20 minutes they bother my eyes these are for my son i just tried theme out around the house and they work you can see a good distance you are able to make thing out but you can not read lables and the screen is small and i would not pull to hard on the straps they do not seem to be that great but it is a toy and i got mine for $68.88

My husband was having the same problem at first. There is an on/off switch on the top near the batteries.

correct -- there is just one view window for the night vision - and it is in the right eye.

The goggles take five(5) "aa" batteries. I use the alkaline type for digital cameras, they last about 4.5 to 5 hours constant on in use.

No, and I wear glasses. Just put the unit on slightly loosely, and adjust the straps for comfort. There is plenty of room inside them for your glasses.

With adult supervision, 5 to 8 years old, after that age most kids follow the instructions.( from 9 to ? and on up)
