Blinking makes a sound

Many people experience a "clicking" sound when they blink or press the corners of their eyes. Why is this? In fact, when it comes to this issue, it has a lot to do with the eye fatigue that we are concerned about. Generally speaking, if there is a sound when blinking, it is probably caused by dry eyes or prolonged use of the eyes. If you encounter this situation, you need to relieve eye fatigue in time.

Why does pressing the corner of the eye make a sound?

The eyeball is covered by eyelids, and the eyeball moves in the eye socket under the protection of the eyelids.

The corner of the eye is a shallow cavity formed by the folds of the palpebral conjunctiva and the bulbar conjunctiva. There is water in this area. Why do some people make noises in the corners of their eyes? In fact, it is because air may enter this cavity when the eyes are opened and closed. At this time, air and water are mixed together under the pressure of external force, and noise may occur. In fact, it is the sound caused by the friction between the air and the surface of the eyeball.

Under normal circumstances, if the tear film on the surface of the eye is evenly distributed, there should be no sound. However, when the water is unevenly distributed, air will enter. When air and water meet, if there is external force pressure, a sound will be produced.

What factors are related to ringing in the corners of the eyes?

When the eyes are tired, overused, or looking at the computer for too long, the water on the surface of the eyes evaporates too much, the tears outside the eyes will decrease accordingly. At this time, the tears will be unevenly distributed and this problem will occur.

Staring intently for a long time can cause great harm to the eyes. Firstly, high nervous tension can cause swelling of the eyes and chronic deterioration of optic nerve function. Secondly, long-term close-range use of the eyes can promote the development of axial myopia. In addition, the reduction in blinking causes the eyeball to lack lubrication and protection. According to statistics, a normal person blinks about 15 times per minute, but when concentrating, it is only 2-3 times. This causes excessive evaporation of tears on the surface of the eye, which cannot be replenished in time. Over time, it causes inflammation on the surface of the eyeball, which is one of the main reasons why there is sound when pressing the corner of the eye.

This may happen if you have dry eyes. However, when the eyes are too dry, there is too little water in the eyes and no sound will be produced. Only when there is both water and air and they reach a certain ratio will a sound be produced.

The tear duct of the eye is connected to the nasal passage, so when the nose becomes inflamed and swollen, the nasal passage becomes narrower. At this time, the air in the nasal cavity may also enter the cavity at the corner of the eye, and then a sound will appear when external force is pressed.

In addition, this situation may also occur when there is inflammation in the body, because inflammation in the body may cause edema, and the eyeball may also be edematous, mainly conjunctival edema in the conjunctival sac. At this time, the cavity will be larger. If the water on the surface of the eyeball is unevenly distributed, more air will enter, and sound may occur.
