What happens when eye blinks?
When you blink, your eyelids close and then reopen quickly to moisten your eyes with tears, clear away any debris, and help prevent your eyes from drying out. Blinking also helps to reset your focus and keep your eyes lubricated for clear vision.
Why planets don't blink?
Planets do not blink because they do not emit their own light - they reflect the light from the sun. They appear as steady, non-blinking points of light in the night sky due to their stable orbits and distance from Earth. Blinking is typically associated with closer and more dynamic sources of light.
Why do you tend to blink less when you think more?
You are using too much of your brain when you think! So much, in fact, that you forget to think to blink!
Why does the Rainbow disappear if you keep looking at it without blinking?
When staring at a rainbow without blinking, your eyes become fatigued and desensitized to the colors, causing the rainbow to fade from view. Blinking helps refresh the visual receptors in your eyes, allowing you to see the rainbow more clearly.
What are the theories of Lamarck and Darwin on why cave fish loose their eyes?
Lamarckian evolution is based on the notion that changes that happen to an organisms physiology are passed on when it reproduces. Taking this to an extreme to show why it has been discredited, a person who loses their arm during their childhood does not have babies that are born with one arm. With regard to cave fish, Lamarcks theory of evolution argues that they lose their eyes during their life, and pass on this "lack of eye-ness" to their offspring. Modern genetics has further dampened this idea, as acquired characteristics are not carried in genes. Darwinian evolution argues that, at some point during the cave fishes history, a genetic mutation caused one to be born with no eyes (or more likely, one was born with slightly less functional eyes). These fish, due to the nature of their dark environment, would be at no disadvantage to their fully sighted brethren. Eyes can easily get infected or irritated, so nature may have favoured on the side of the eyeless ones. Over time blind cave fish became dominant, eventually reaching the pinnacle of existence by being discussed on the internet. Hope that helps.
