Night vision goggles, duh.

Yes that's the way to go.

I forgot to mention another huge advantage to colored lights, particularly red. Insects aren't attracted to them so you can use, say, a headlamp, without fear of getting attacked by the dreaded june bug or the array of other mysterious buzzing insects.
I wandered till the stars went dim. |

In total darkness however ambient night vision is useless.
Long wave IR devices use ambient heat to image.
FLIR is the ticket plus they detect people in the open easily.
FLIR systems are cheaper now and many don't require cryogenic cooling to operate.
These may be suitable:

Just when I thought I was out... they pulled me back in.

I know that when waking up or going from a dark place to a light place it's best to close one eye and allow the other to adjust. Then, the closed eye will adjust faster.
Take nothing but pictures.
Leave nothing but footprints. |

But if the majority of the structure/tunnel is the same temp, FLIR won't show crap since it is a temperature gradient imager.
That said, if you get an IR module (TNVC Da Torch, etc) your ambient night vision work, it'll just be reliant on the IR module.

An eyepatch would work but as others stated, you lose all depth perception and unless you're a hunter, you will walk into a lot of not so friendly stuff. I spent a decent amount of time behind a scope so I'm less affected by it but most people are severely handicapped with 1 eye closed. I had an eye injury a year or 2 ago & the ER doc said I still had better vision in that eye than my unaffected eye which is supposedly my "dominant" eye.
Red, Green or Blue are all easier on the eyes at night than white but green is the easiest to see at the lowest output levels. I believe red is used more because it's less visible at a distance but I could be wrong. Red is also closer to Infrared &that could be another reason it's used more.
Another option which keeps getting cheaper is NV technology or NVG's. As the current military technology (gen 4 or so I believe) gets better the civilian generations (gen 1 & 2) get cheaper. For good depth perception you have to get the binocular version (more expensive but worth it). The monocular version is good for certain applications but if you're in an unfamiliar area with a lot of hazards you want the best depth perception possible
Not tooting my own horn but the primary reason I carry a light is for my wife who claims to have good night vision but walks into stuff at home whereas I can spot my cat (Russian Blue, all gray) across the house without catching a glint of her eyes. You can also train your eyes but you have to do it slowly otherwise you can damage your eyesight by trying to see in a pitch black room. Try going to a dark area of your town or city (preferably a safe area) and just walk around trying to stay in shadow and focus and pick out details on buildings or rats without using artificial light. You'd be surprised at the results

There is also a FLIR camera for most smartphones and I think it's around $250-$350 and who doesn't go anywhere without their phone nowadays? It's another option to consider

I haven't tried it for myself for it's a proven company with a good track record. It's cheaper than a FLIR scout and gives more detail (IMO) than NVG. It can be deceiving with reflective surfaces though, if you point it at a mirror or polished metal you will see your own outline and might freak out depending on what kind of person you are
