This is the opposite of what my vet told me very recently.
Horse’s eyes are better designed to see in the dark than ours are.[/QUOTE]
Horse eyesight is very different than our own in many ways – including their poor depth and color perception, but from my understanding (from both reading and classes on the subject) their night vision is not much, if at all, better than ours. I’m on mobile now, but when I get home I can scrounge around for some study links.
I think as a whole asking them to ride at night is not a big deal, but I would remember that if you are riding “in and out” of a beam of light (ie head lights) it may be a challenging question to ask.
