If you are indeed on a "trek" and won't be walking at night, I can't imagine why you would want to burden yourself a piece of equipment that is not essential. A good head band LED outfit is perfect for trekking. --Not to mention the enormous cost you seem to ignore in your thinking about upgrading. Actually, most experienced trekkers would laugh at carrying even the device that you have.
I found some material relating to the red lenses from the American Optometric Association.
For maximum utilization of scotopic vision, 20 to 30 minutes in total darkness are required to attain satisfactory retinal dark adaptation. An alternative is to have the aircrew member wear red goggles for 20 to 30 minutes before flying. When worn in normal illumination, red goggles will not interfere significantly with the ability to read most maps, charts, manuals, etc., as long as the printing is not in red ink. Red goggles block all light except red, which enhances rod dark adaptation because red light does not stimulate the scotopic system. There are some drawbacks to wearing red goggles or using red cockpit lighting. When reading maps, markings in red on a white background may be invisible. Red light also creates or worsens near-point blur in older far-sighted, presbyopic (decreased near focusing ability due to age), and pre-presbyopic aircrew. Under red light or using red goggles in normal light, red light is focused behind the retina due to the optics of the eye and more "near focusing" than average must be used to provide a clear image when reading at near.

There are optics out there for every person and every way to pass time.
In the military I went from the PVS-7 to the PVS-8 and the jumped to the 14's. Just a world of difference in quality and comfort between to monocular night vision and the old "Cyclops" and binocular systems.
As a civilian (as in you will not be running and gunning) dropping massive amounts of money on optics to play with is insane. I carry a Night Owl X-Gen 3X Monocular when I am trekking, camping, and kayaking. I carried similar models when I was deployed in Iraq during several deployments. They are lightweight, cheap(ish), and fairly ruggedized.
I would definitely suggest you look into them if you haven't already.

Pricey ... but you won't ever buy another. I prefer the monocular as it allows me something akin to normal vision and I don't become disoriented walking about. The head-strap this comes with is all you need and the device works well mounted on my AR.
This was the last piece of gear I bought, but considering what I bought it for, it should have been the second or third, in hindsight.
Good afternoon Ats hope all is well. Sorry to create such a small thread, no conspiracies here or anything
Later this year me and a few friends are doing a 5 day trek through the cairngorm mountain range in Scotland. I have most equipment and I'd say I'm a pretty good amateur when it comes to trekking and what not. I currently own a hand held night vision monocular it does the job for spotting wild life and also on a trip to wales was able to help me and a friend tell whether some lights we saw at night was an army land rover or walkers.
Anyway I get the point. I'm looking at upgrading my night vision equipment. Several questions if like to share before purchasing a new toy
1. My monocular is ok .. However id like something with a bit more power. Is it worth getting head mounted goggles or go with a nice decent pair of night vision binoculars
2. If I were to buy head mounted goggles I've seen different types. I've seen one with just one eye piece, a night vision sight that sits over one eye while the other eye is free of any device and can see normally. The second is where you have an eye piece for both eyes. Which would be best ?
3. If anyone can advise me or can share their experience with night vision as to what to go for best of happily listen to people's suggestions.
Am willing to buy products from around the world so if anyone has any websites that arnt in the UK is still be happy to look. Any questions are welcome if it helps narrow down what I need
Thanks again ats users
