It means you have one eye open. If you mean the idiom "sleep with one eye open," it means that you are staying alert at all times in case of disaster.
no
I believe a shark sleeps with one eye open.
One of its eyes may be hurt or it may have pink eye
This is completely natural behavior. When a gerbil opens their eyes, they often only open one eye at a time. In a few days the other eye will open.
No. The mouse is perfectly normal. Some times the eyes open at different times. It's all good though
it is on one side of face
Don't worry, its completely normal if he does this sometimes. if he is constantly doing it, consult advice from a professional. He should open his closed eye once you get his attention- if this is the case, don't worry. If he is unable to keep both eyes open at the same time then he could have some eye muscles week or possibly a disease in the brain. Any other animal inquiries? Contact me :D
A dolphin
they can sleep long with one eye open -they'll drown if both are closed also their eye is open to sense danger or they'll die.
If it is just the child has some sleepy eye crud stuck to eyelashes, then a warm washcloth or a shower/bath should help open eye. But, If it isn't the sleepy eye crude----You might NOT want to open the eye. I would make an emergency Peditrician apt, or empergency eye Doc apt!! If it has some particle in there, I doubt you will have the tools and expertise to remove the product, if he got his cornia damaged by a sharp object, You wont be able to see it with the naked eye. Eyes are a serrious deal, we only get 2.
every dolphin sleeps with one eye open.
