Eyesight, and the speed of light.

When using the hypothetical, “If the Sun turned on from off, it would take 8 minutes for light to reach Earth, and, you wouldn’t be able to see the Sun for 8 minutes and 20 seconds, even if you were looking in the Sun’s direction. Why not? Do your eyes suddenly not work? How would a person not see the Sun, if it turned on from off, and they were facing it when it happened? These things are ridiculous.
