On or about: 01-06-08  20:55, Bjorn Forsstrom did engage James Bradley
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?
