With so many different night vision devices to choose from, why would one choose to use night vision goggles as opposed to a monocular or some other type of scope device?
There are several reasons. The first, and most not so obvious, is the that the army has traditionally trained many of their soldiers to use the night vision goggle. With a head or helmet mount, the goggle allows for a hand-free operation, giving the soldier the ability to use a gun, operate a tank or vehicle, or fly a plane or helicopter while wearing the goggles.
The second reason, and the stronger of the two, is eye-strain. Looking through goggles is easier on the eyes and produces less eye strain than looking through a monocular or scope type set up. If you are operating a tank, armoured vehicle, doing a ground survey, performing a tactical area search and rescue, or flying a plane or helicopter the night vision goggle (aviator night vision - another article coming soon...!) would be the correct choice based on the minimal eye strain. Looking through goggles allows your eyes to adjust to the green color based vision without having to deal with the darkness of night poking in from your other eye. This can easily cause a headache, which you obviously don’t want when operating a vehicle or plane on an important mission. It is one thing to operate a vehicle or plane and another to concentrate on your aim through a scope, where you typically close one eye to get a better view of the target.
The view through NVDs can be a lot like looking down a tunnel. Your normal field of view is almost 190 degrees – but that is cut down to 40 degrees with NVDs. That side -- or “peripheral” -- vision you’re accustomed to, and from which you often see dangers, is just not there. To adjust for that you must constantly turn your head to scan for the dangers on either side of you that you can’t see in your narrow field of view. Not the greatest in ground battle situations, but what can you do? That's the price for being able to see in almost complete darkness.

It is really nice to use night vision goggles especially for armies or soldiers that are usually fighting in battles. This is more comfortable and user friendly. They will not hassle while they are on operation because night vision goggles do not need to be hand held either. This is a good choice.
ReplyDeleteSo what else can you do with a night vision scope? Well, for one thing, if you are a hunter of animals that only come out at night you would be in a much better position to see your prey. I found a little family of racoons in my backyard this summer and spent several evenings looking for them with a flashlight. There was four little baby racoons and a momma. I usually found them with my hearing rather than sight. However, I think it would have been much easier if I had a pair of night vision goggles or a night vision scope to help me.

Evening eyeglasses are telescopes or field glasses with a huge size purpose. Large contacts can collect while lighting, thus accelerating lighting with simply visual means and empowering the individual to see better in the black than with the exposed eye alone. Often night eyeglasses also have a pretty big quit scholar of 7 mm or more to let all collected lighting into the visitor's eye. However, many people can't take benefits of this because of the restricted dilation of the individual scholar. To get over this, defense force were sometimes released atropine eye falls to enlarge individuals.[when?] Before the release of picture intensifiers, night eyeglasses were the only method of night perspective, and thus were commonly used, especially at sea. Second World War era night eyeglasses usually had a contact size 56 mm or more with magnifier of seven or eight. Significant disadvantages of night eyeglasses are their huge size.
