I believe some people sleep with their eyes partially open. But sleeping with eyes totally open I think is impossible unless you have a dissability/abnormality or have been to accident. The only creature I know that sleeps while eyes are open is the fish as well as some big cats like leopard which sleeps with one eye open.
Have you ever seen someone sleeping with their eyes open? It may look strange, but there are indeed abnormalities in the eye that cause the eyes to open when they fall asleep and that can also happen to you. Then is it safe if this happens?
Why are eyes open while sleeping?
When you fall asleep, you will not know whether your eyes are closed or open. If when you wake up your eyes feel itchy, dry, and tired, chances are that you are sleeping with your eyes open or partially closed. This can occasionally occur in healthy people.
However, if symptoms continue to appear after waking up, you may have eye disorders. For example, nocturnal lagophthalmos or nocturnal fatigue.
Symptoms of nocturnal lagophthalmos
In addition to dry and itchy eyes, there are other symptoms that can occur if you experience a nocturnal disorder, such as:
Red eyes Blurred eyes The eye feels sore or hot Easy glare Eyes feel like being possessed by a foreign object
What causes nocturnal lagophthalmos?
Nocturnal abnormalities occur as a result of facial paralysis, which is the part of the orbicularis muscle in the eyelids that can be temporary or permanent. The cause is infection, stroke, former surgery, trauma, or bells palsy (weakness in facial muscles).
In addition, nocturnal lagophthalmos can also occur after undergoing blepharoplasty, a procedure to remove excess skin from the upper eyelid when aging occurs. This surgery can indeed make the face younger, but the risk of developing lagophthalmos is greater.
There are several diseases that can also cause sleep with your eyes open. For example lyme disease, chickenpox, goiter, polio, leprosy, diphtheria, Guillain-Barré syndrome, moebius syndrome, and neuromuscular disease. Eye disorders such as exophthalmos (protruding eyes) can also make it difficult for a person to close the eyelids. Then, the upper and lower lashes that are too thick can also cause the eyes to close perfectly.
I think it is a possibility since I even witnessed it myself. There's this person with eyes open but not making any movement. Then I realized he is sleeping.
I even experienced it as well. My eyes are open but my brain seemed absent. I am even dreaming in my sleep, though it toom just seconds of sleep.
