Cheap Chinese Night Vision— Hidden Gem or Overhyped?
For the past few years, the night vision community has been waiting for one thing:
When are we finally getting real night vision that does not cost an insane amount of money?
But reality has been pretty brutal. Analog night vision is still expensive, especially when you start talking about high-performance image intensifier tubes, decent glass, and a solid housing. Anyone who has spent time in the NVG world knows the big cost drivers: the housing, the optics, and the intensifier tube.
And once you move from a monocular to a binocular setup, the cost jumps fast. Two tubes, two optical channels, and a more complicated housing — that is where the money goes.
That is exactly why more overseas buyers are starting to pay attention to Chinese night vision devices. Not just because they are cheaper, but because some of them are starting to hit a much more realistic balance between price, weight, field of view, features, and actual analog night vision performance.

How to Check If the FOM Value of Your Night Vision Goggles Is Real
When buyers choose night vision goggles, they often see numbers like FOM 1,600, FOM 1,800, FOM 2,000, or even higher.
But one question is very common:
Is this FOM value real?
This is an important question, especially for dealers, wholesalers, and product buyers. A higher FOM value usually means a higher price. If the FOM is not real, the buyer may pay for a high-grade tube but receive a lower-grade product.
The good news is that buyers can do some basic checks before and after receiving the device. You may not be able to test the exact FOM value at home, but you can find many warning signs by checking the report, the device, and the image quality.
Below is a simple step-by-step guide.
