> Lights destroy your natural night vision.
Yes. I can't walk the dog in the dark with a torch, I hate having my vision limited to the torch beam, it's far too restrictive.
I do, however, now take a torch out in the dark, a little one that dangles off my wrist. Having it shining directly downwards doesn't change my natural vision, it's on so people can see
me, if I see anybody approaching, I flash the torch beam on Buster to make sure he can be seen too.
The only problem I've had with the toch on my wrist is nearly blinding
myself - I forgot I had the the torch on my wrist as I bent over Buster, in his hi-viz vest, to get a poop-bag out of the little bag on his harness, the torch beam caught one of the reflective strips on the vest as I was very close, had to stand around for a few moments waiting for my eyes to adjust!
The field I walk Buster in is
extremely dark in one place some nights (the hill). Buster almost
stood on a black dog as we were going up the hill in the field. I had my hi-viz trousers on, Buster had his hi-viz vest on,we simply did not see the man & his leashed dog walking down towards us. They obviously didn't see us either. We gave each other a bit of a shock, I'm just very glad the old chap was not afraid of Buster or he could have been really shook up. We had a little chat while the dogs greeted & sniffed. But, boy!!! what a shock that was. That's when I started wearing the torch on my wrist, at least I can be seen. I'd hate the look of Buster to frighten somebody at night, it's a bad enough shock bumping into a more normal size dog, so I'd rather we could be seen to be there.
