What is it like sleeping with eyes half open?

First of all, it should be made clear that sleeping with half-open eyes has nothing to do with the size of your eyes.

Sleeping with half-open eyes refers to an eye sign or symptom, medically known as incomplete eyelid closure, also known as lagophthalmos, which can occur in one or both eyes.

Under normal circumstances, when we fall asleep, our upper and lower eyelids are closed together, and the palpebral fissure disappears. The benefit of closed eyelids is that the human ocular surface (conjunctiva, corneal tissue) can be covered by the tear film, ensuring the absorption of nutrients, the smoothness of the ocular surface tissue, and the normal circulation of tears.

A small number of normal people will have very slight incomplete eyelid closure after falling asleep, which has almost no harmful effect on the ocular surface tissue. Most of the incomplete eyelid closure is pathological.

There are many reasons why the eyelids may not close completely, such as:

Trauma causing local skin and eyelid tissue defects;

Exophthalmos: thyroid-related eye disease, retrobulbar mass, intraorbital tumor, etc.;

Facial nerve paralysis, resulting in paralysis of the orbicularis oculi muscle;

Ectropion: Causes such as senility and scarring can all cause varying degrees of incomplete eyelid closure.

What harm does sleeping with eyes half open have on your body?

When you sleep with your eyes half open, many symptoms may occur due to varying degrees of incomplete closure of the eyelids.

When sleeping, the conjunctiva and cornea of ​​the eye surface tissues are exposed to the air for a long time, which can cause dry eyes, tearing, foreign body sensation in the eyes, conjunctival congestion and edema. In severe cases, it can cause corneal epithelial damage, shedding, and even corneal ulcers. Common non-healing conditions include corneal perforation, leading to endophthalmitis, etc.

In addition, incomplete eyelid closure will definitely cause unsightly eyes and face.

Can sleeping with half-open eyes be cured?

Sleeping with half-open eyes is due to incomplete eyelid closure, so the treatment is to close it, and the treatment should be based on different causes. Most cases can be improved after treatment, but it is difficult to recover.

1. When the primary disease cannot be treated (such as corneal staphyloma, congenital glaucoma, etc. that are difficult to treat) or surgery is not possible, conservative treatment can often be performed. For example, artificial tears can be used frequently in the eyes during the day to prevent the eyes from drying out, keep the ocular surface tissue moist, and stabilize the tear film. Wet chamber lenses can also be used to protect the ocular surface.

If there is inflammation or infection, you need to further use anti-infection and anti-inflammatory eye drops to repair the ocular surface tissue as soon as possible. When sleeping at night, you can apply chlortetracycline, ofloxacin eye ointment, etc. to close the open palpebral fissure and isolate the ocular surface tissue from the outside air.

2. Incomplete eyelid closure caused by ectropion, whether it is senile, scar or mechanical, generally requires surgical correction to return the eyelids to their normal position and allow the upper and lower eyelids to close naturally.

3. For exophthalmos caused by thyroid-related eye diseases, retrobulbar masses, orbital tumors, etc., the primary disease should be actively treated. Consult with the endocrinology department and neurosurgery department to reduce exophthalmos.

4. Patients with facial nerve paralysis are advised to go to the neurology department for examination, identify the cause, and actively treat it. At the same time, they should consult an ophthalmologist and treat the symptoms.

5. For patients who are bedridden for a long time or who have difficulty solving problems such as dry ocular surface tissue and keratitis with the use of eye drops or eye ointments, surgery to symmetrically suture the upper and lower eyelid margins can be performed to maintain passive eyelid closure and protect intraocular tissues.
