Is the perception of light the same among all animals/insects?

[joel321]

Just the mere perception of speed of movement is different from a fly from a human being. If that is correct, do both a human and a fly PERCEIVE light at the same speed? Humans may be able to understand the limit of the sound of speed but if a fly can react faster than a human can, that means that the fly understand the speed of sound/light way faster than then human can. NOW I'm wondering is the how does the speed of light works in a fly's eye. OBVIOUSLY< the fly must react faster to the speed of light in it's eye than in a human eye!!!! To me means that the speed of light is just a perception! and not 100% the ULTIMATE CONCRETE TRUTH OF LIFE! I mean, how can you understand what's outside the human perception? ONLY, limited by the human perceptions...that OBVIOUSLY, other animals surpass our perceptions of mother earth!

My understanding is that it is the frequency that varies in the eye responses of different animals and insects, not the speed.  The speed of light is,
after all, constant.  For example, I really believe my cat can see in the infrared range along with his night vision.  I have been trying to test this and so far...I believe I am right.

Pirate this is a complicated thing to understand. Your average person WILL not be able to graspt such things but if we start to think about BIG NUMBER AND DISTANCES we can start to grasp the scope of things. Yes in the earth scope of things, things in PERSPECTIVE DO make sense, but out side of it is where things get a "little blurry" anyway here's another video that may show the "perspective" just one needs to read between the lines...lol

 No, time is not equally perceived ,light has requirement of time.

[sm0ky2]

all animals, insects, plants, etc. perceive light in a different way, a different quantity, and yes at a different rate of processing.
While the light itself, moves at generally the same velocity,
the rate at which this light is absorbed, the distance it must travel from the surface of the receptors to the brain, and the amount of light being processed at a time are vastly different.

the size of the human eye is 1000 times larger than that of a fly, which means the light has to travel 1000 times further just to reach the back of the eye.
a fly's eye is also closer to its' brain than a human eye.
the surface area of the eye affects how much light information is received,
the human eye is round, so its surface area is easily determined.
a Fly's eye, however, is multi-faceted at various angles, which increases the surface area for the size of the eye.
a fly processes more light information than an insect with a round eye of the same size.

also, brain function, plays a lot in the rate of speed the information is processed. the human brain not only processes the light information, but categorically labels the recognizable images in a much more complex manner than a fly.

So, a Fly, by nature of its organism, can input and process light much much faster than a human.
Time would be experienced slower by the fly, and by that I mean, more visual things occur in a second of time, than humans can perceive.
for us, that second flies by, but for the fly theres a lot that goes on.

also, as Bill pointed out, there are differences in frequency of light being processed, which can include more or less information, from creature to creature. some creatures see things that others do not.
