Some people feel that their eyelids are suddenly shaking, without seemingly any reason for this to happen. Sometimes these are soft, barely noticeable tremors and other times these are of greater intensity. As for the duration, this can be from a few seconds to several hours or days, until it finally dissipates.
The feeling is very annoying. Whoever experiences it feels as if his eye vibrates or “beats. ” Sometimes the intensity of the movement is such that it leads to seeing the objects as if they were moving. However, in most cases in which the eyelid trembles there is nothing to worry about.
It is almost always a muscular reaction that can be considered normal and that as it arrives, it also goes away, suddenly, without generating any consequences. Only in some exceptional cases does the eyelid tremble due to the presence of more serious disorders or disorders.
When the eyelid trembles
Most people have an eyelid shaking at some time. Normally, it is a gentle vibration, which disappears on its own in a short period. This condition is called “blepharospasm” and corresponds to an involuntary spasm or contraction of the muscles surrounding the eye.
This type of tremor only warrants a medical consultation if any of the following situations occur:
- The tremor in the eyelid remains for more than a week.
- Tremor not only affects the eye but also other parts of the face.
- The contraction is so strong that it closes the eyelid completely.
- There is inflammation, redness or discharge in the eye in which the eyelid trembles.
- The upper eyelid falls. This is known as “ptosis.”
In other cases, this type of problem is due to causes that have to do mainly with lifestyle. The main reasons for this to occur are set out below.
Most of the time the eyelid trembles from stress. This state causes a series of hormonal changes that affect the functioning of the muscles. And it is precisely the smallest muscles, such as those of the eye, that are most affected. So this type of involuntary movement is a sign that you need to relax.
Lack of sleep
Another reason why tremor appears on the eyelid is lack of sleep. When you don’t get enough sleep, you put your eyes under extra effort and lead to eyelids weakening. Tremor is a reaction to this overexertion, so it is recommended to sleep at least seven hours each night to prevent this from happening.
Sometimes involuntary spasms in the muscles are due to the deficiency of some substances such as vitamin B12, magnesium or potassium. Likewise, when the body is dehydrated it also tends to cause such reactions. The solution is to ingest more foods rich in vitamin B12, such as fish, meat, eggs, and dairy, and stay sufficiently hydrated.
Sometimes there are visual impairments that lead the eye to try harder than usual. When these problems have not been detected and treated, through a formulation of glasses, for example, they can lead to the eyelid trembling. That is why it is important to make periodic vision checks and follow the recommendations given by the specialist.
Dry eye is a condition in which there is not enough moisture in this organ. In this case, involuntary tremors appear as a mechanism to try to hydrate the eye. This is a very common problem in people over 50, who work too many hours in front of a computer screen, take antihistamines or wear contact lenses. There are eye moisturizers to keep the eye in the right conditions.
Some substances dehydrate the body for its properties. The most common are coffee and alcohol. Both cause the body to lose fluids and, therefore, lead to tremors in the eyelids. It is best not to exceed the consumption of these substances and drink water frequently.
Frequently, those who suffer from any allergy have redness and itching in their eyes, as well as excessive tear production. Scratching the eyes releases a substance called “histamine,” which can reach the eyelids and cause tremor. Medical control of allergies is essential so that this does not happen.
