Thermal binocular users, advice on double “black eye” please.

[Pellet Pinger]

A wander round the Stalking Show yesterday found me picking up gear i normally wouldn’t
I had a look through the Nocpix H35 Quest amongst others and was instantly impressed by the size and simplicity, the image was good in the circumstances.
I currently use a HIK Condor CQ35L and more than happy with its performance and features, when foxing i pretty much have them glued to my face as some of the land i shoot is the type that one could appear from nowhere quickly, so when walking around i do notice the old Black Eye and when i shut one and open the other and vice versa its clear the night vison in my thermal eye is reduced considerably. All my shooting is on foot so walking around in the dark i’m relying on my “good eye” to avoid tractor ruts etc.
My question is, surely looking through bino’s is just going to compromise both eyes nightvison whereas a monocular will only do one.
Im worried im going to be stumbling around everywhere if i switch to binos!!
Opinions please.

I'd be interested to hear this too. I find I have a similar issue at night, I use red monochrome most of the time, hoping that this might help, in the same way you would use red light on the bridge of a boat at night. I'm not sure if it helps, interestingly, the tone of red looks different from left eye to right.

There's no real way round it really. Rhodopsin, or 'visual purple' is a protein in the eye that bleaches with exposure to light. It takes about 30min to regenerate once it's bleached out and for low light vision to return to normal.

You can minimise it by reducing the intensity of light emitted (most effective with image intensifying or night vision devices), but that can often reduce the fidelity or contrast of an image, particularly with TI.

Thanks for that, very interesting!

Honestly - i use thermal binos most nights and you get none or virtually no black eye at all
I suffer terribly with a monocular

Where in the country are you PP ?

Coming home from the Stalking Show and telling the missus that you've just blown a couple of grand on a new thermal is pretty much guaranteed to result in a double black eye. It's a well-known occupational hazard.

Thanks, this is what i can’t get my head around, surely both eyes have reacted the same and you don’t notice it as black eye.
Maybe im overthinking it!

Easy fix for that one mate!! Need to know basis, & she definitely doesn't need to know!

Your not over thinking it.
Both eyes are affected the same so users don't notice it.
Your still looking at the same type of screen as what's in a monocular. Only difference is your looking at a screen with each eye.

Correct both eyes will suffer so no way of telling. I use my monocular with L eye and turn down brightness to lowest setting normally 2 or 3.Still get brown eye.

Same, thermal left eye scope right eye, couldn't see a thing through scope otherwise

I used to have problems with a thermal monocular, but none whatsoever with the thermal binos.

It probably still happens, but because it is both eyes, not just one, it might seem like it is less affected as both are now reduced in night vision efficiency.

Was going to say come look at mine but maybe a bit far

 

[jall55]

If both are are affected then i wonder why i can walkabout without bumping in to stuff like a blind man ?
With a monocular i actually cannot see through my eye if i close the none affected eye - surely if both are affected ........well as i said - blind man bumbling about ?

 

[Jackal8]

Honestly, I’m not sure there’s a permanent solution currently. What I’ve done, is look for the thermal with the dimmest screen and buy it. Binos I don’t know, the magnification is too big for the terrain where I hunt.
