Eyes rays are far faster then light?

Question

when you compare eyes with PIR motion detector, our eyes should send some kind of signals to find objects like PIR motion detector. According to this, our eyes must send signals far faster then light. For example, light takes 8.20min to reach the earth from the sun, but, our eyes take nearly 0sec to see the sun. Am i right?

Answer 1

Our eyes see because of light. Eyes don't emit any rays or waves that have speed or velocity. What I mean is that we see as fast as the light, since light enters through our eyes maintaining its speed.

Answer 2

You are absolutely wrong. You say that our eyes send some rays that's why we are able to see the objects. If it was true we should be able to see even in the dark. Can you see in the dark? The reason we can't see in dark is that objects are seen only when there are light rays. You also say that we can see the Sun instantly. Yes we can see. But the Sun  that you see is the one that is Eight minutes before not exactly at the time of watching. The distant stars you see might be some millions years back not present. We don't what they look like at present. It will take another million years.

Answer 3

You eyes are "receivers only" they do not "send out" anything they simply receive light and send impulses to the brain, which interprets these signals as colors and shapes.

Answer 4

This misconception goes back to the early Greeks; it's amazing it's still around.

Answer 5

NO and NO

Answer 6
