Why does tiredness effect the eyes?!

Your eyelids have muscles. The muscles get tired (Such as when you are running your legs feel week when you stop...) So, the eyelids get tired after being held open all day and need to rest....

Listen, eyes need rest as you do.
They need relaxation after seeing so much horrifying things in all the day like your penis which alway go straight up and down and then fall up again when see a hot girl around.
I know eyes need relaxation, that's why i take a deep breath and close my eyes for 10 minutes and then open my eyes and i could feel the change. Try it you will surely find relax.

XD Knowledge

coz it seems that for the brain to rest it needs to stop the eyes from sending back information that needs to be processed, if you think about it the part of your brain that processes the things your eyes see never stops working, even when we are not really looking at anything our eyes are still sending back info that has to be processed .
why we get bags under our eyes i don't know

my head

Because your eyes and eyelids need a rest as well, so when you are tired you are forcing them to stay up when they need rest.


Good luck
