Eye tremor is a term used by most people to refer to the sensation of vibration in the eyelid of the eye. This sensation is very common and usually happens because of the tiredness of the eye muscles, being very similar to what happens in a cramp in any other muscle in the body.
In most cases, the tremor lasts for a day or two, but there are cases where it occurs for a few weeks or months, making it a major nuisance. In these situations, you should consult an ophthalmologist or a general practitioner, as it can also be a sign of vision problems or infection.
In addition, there are situations in which the eye trembles only, not the eyelids. When this happens it is called nystagmus, which is more difficult to identify than eyelid tremor, and is checked by a doctor on an examination to diagnose health problems such as labyrinthitis, neurological disorders or vitamin deficiencies. See more what is nystagmus, main causes and treatment.
9 main causes of eyelid tremor
Although the tremor is caused by tired eye muscles, there are several causes that can contribute to this situation, which include:
1. Excessive stress
Stress causes several changes in the body, especially in the functioning of muscles, due to the action of hormones that are released.
In this way, smaller muscles, such as those of the eyelids, may suffer greater action from these hormones, moving involuntarily.
What to do to stop: if you are going through a period of greater stress, you should try to do relaxing activities such as going out with friends, watching a movie or taking yoga classes, for example, to help balance the production of hormones and stop the tremors.
2. Few hours of sleep
When you sleep less than 7 or 8 hours a night, the eye muscles can become quite tired, as they have had to work for several hours straight without rest, also increasing the release of stress hormones. When this happens, the eyelids become weaker, beginning to shake for no apparent reason.
What to do to stop: it is recommended to sleep at least 7 hours each night, creating a calm and relaxing environment to allow a more restful sleep. If you're having trouble falling asleep, here are some natural strategies for faster and better sleep.
3. Lack of vitamins or dehydration
The lack of some essential vitamins, such as vitamin B12, or minerals, such as potassium or magnesium, can cause involuntary muscle spasms, including the eyelids. In addition, low water intake can also lead to dehydration, which weakens the muscles and can cause tremors.
It is also worth remembering that people over 65 or who follow a vegetarian diet are more likely to lack essential vitamins and may experience tremors more often.
What to do to stop: increase your intake of foods with vitamin B, such as fish, meat, eggs or dairy products, as well as try to drink at least 1.5 liters of water per day. Check out other symptoms that can help confirm a lack of vitamin B.
4. Vision problems
Vision problems seem quite harmless, but they can cause various problems in the body such as headaches, excessive tiredness and tremors in the eye. This is because, the eyes work excessively to try to focus on what you are looking at, getting more tired than usual. Here's how to assess your vision at home.
What to do to stop: in case you are having difficulty reading some letters or seeing from a distance, for example, it is advisable to go to the ophthalmologist to identify if there is really a problem that needs to be treated. For people who wear glasses, they should go to the ophthalmologist if it has been more than 1 year since the last appointment, as it may be necessary to adjust the degree.
5. Dry eye
After 50 years of age, dry eye is a very common problem that can lead to the appearance of involuntary tremors that occur in an attempt to help hydrate the eye. However, there are also other factors that can contribute to this problem in addition to age, such as spending hours in front of the computer, wearing contact lenses or taking antihistamines, for example.
What to do to stop: it is advisable to use a moisturizing eye drop throughout the day to try to keep the eye well hydrated. In addition, it is important to rest your eyes after 1 or 2 hours in front of the computer, and to avoid wearing contact lenses for more than 8 hours straight. See what moisturizing eye drops you can use to treat dry eye.
6. Consumption of coffee or alcohol
Drinking more than 6 cups of coffee a day, or more than 2 glasses of wine, for example, can increase the chances of having eyelids trembling, as the body becomes more alert and dehydrated.
What to do to stop: try to reduce your consumption of alcohol and coffee gradually and increase your water intake. See other techniques you can use to change coffee and have energy.
7. Allergies
People who suffer from allergies can have various symptoms related to the eyes, such as redness, itching or excessive production of tears, for example. However, when scratching the eyes, a substance, known as histamine, which is produced in allergy situations, can reach the eyelids, causing the shaking.
What to do to stop: it is advisable to take treatment with antihistamines recommended by the general practitioner or allergist, as well as avoid, whenever possible, contact with the substance to which you are allergic.
8. Use of medicines
Some drugs used to treat emphysema, asthma and epilepsy, such as theophylline, beta-adrenergic agonists, corticosteroids and valproate, can cause eye tremors as a side effect.
What to do to stop: you should inform the doctor who prescribed the medication, to assess the possibility of making any changes to the dose used or even changing the medication, in order to reduce the appearance of this side effect.
9. Changes in the nervous system
The main nerve disorder that can cause tremor in the eyes is blepharospasm, which can affect both eyes and produce repetitive eyelid movement.
In addition, this change can also appear in just one eye, when a blood vessel creates pressure on the facial nerve, causing a tremor, known as hemifacial spasm, which can also end up affecting the muscles of the face.
What to do to stop: It is recommended to consult an ophthalmologist or a neurologist to identify whether it is really a nervous disorder and, thus, start the most appropriate treatment.
When to go to the doctor
In most cases, shaking eyes are not a sign of serious problems and disappear in a few days. However, it is advisable to consult an ophthalmologist or general practitioner when:
- Other symptoms appear, such as redness of the eye or swelling of the eyelid;
- The eyelid is more droopy than normal;
- The eyelids close completely during tremors;
- The tremor lasts more than 1 week;
- The tremor affects other parts of the face.
In these cases, the tremor may be caused by an infection of the eye or problems with the nerves that unnervate the face, which must be identified early to facilitate treatment.
