I think it is a matter of terminology. If the sun is in a snake's
field of view, I'm sure the snake can see it. That's 93 million
miles away. I think what you were trying to say is that snakes can
only see clearly a few feet in front of them, or in other words that
they are near-sighted. AFAIK, snakes have good eyes and can see color.
I don't know how good their eyes could be if they're looking into the sun. <g>
Of course we can't tap into their optic system and see what they see
but I doubt they look at the sun and see it as a distinct circle in
the sky. It's been a while since I've read anything on the subject
but I think that the context of what constitutes range of vision
meant that the animal could see the object clear enough that the
animal could deal with it appropriately.
Of course there is also the possibility that the animal they tested
was near-sighted. If aliens came to Earth and decided to test me to
rate the eyesight of the human race, they'd think we couldn't see
clearly more that a few feet in front of us. <g>
