text: how come whenever i close my eyes to go to sleep i feel them go cross-eyed. when i open them, they uncross.? i have been doing eye exercises to help w/ my vision. but i have stopped for about a week now. im afraid that i might be straining my eyes when i go to sleep. you better quit sleeping all together.  your eyesight may depend on it.  i think if you get a really big cup of coffee, it shouldn't be a problem for you.   my fish sleeps with it's eyes open.    cheers!
