regarding, but not limited to: Cats eyes
BF>> I know that a cat can adjust the incoming light in the eyes by open or
BF>> close the pupil.
BF>> The other day a used a flashlight right in the eyes of one of the cats
BF>> and normally I think that that would have blinded him but reacted at my
BF>> movement just beside the lamp.
BF>> Why wasn't he blinded?
JB> Try the same on yourself.
BF> I did and I didn't see anything, and still doesn't (almost).
Was the movement at the same *instant* that you turned on the flashlight,
directly in his eye? I think the instinct is to 1) blink, 2) dilate, 3) squint.
If you miss the blink, I think their retina is otherwise ready to go. How
bright is your flashlight?
JB> The response should be pretty fast. Besides, you
JB> had one flashlight, and the cat has two eyes.
BF> My eyes are futher apart than the cats.....
...Saying? Is your flashlight double headed?
