Is it normal to sleep with your eyes slightly open?
Mostly.Normal for most people
Yes, some people sleep with their eyes partly open, and it’s often harmless. If you wake with dry, red, irritated eyes or blurry vision, it’s worth getting checked.
It can happen when your eyelids don’t fully close during sleep. Lots of people don’t realize they do it until someone else notices, and it’s usually not a big deal if your eyes feel fine.
The main catch is that an open gap can leave your eyes dry or irritated. If you regularly wake up with redness, discomfort, or blurry vision, ask an eye-care professional about it.
