When we are under pressure and stress, we may experience a sensation of eye twitching along with other symptoms.
According to the American Academy of Ophthalmology, this type of spasm occurs when one or both eyelids tremble or close suddenly.
Below we explain what each one consists of and their general causes.
Why is my eye twitching?
Broadly speaking, this symptom is due to the consumption of stimulant substances, stress, insomnia, among others. These are the types of eye spasms:
1. Eyelid twitching
This is the most well-known spasm . Experts from the American Academy of Ophthalmology describe it as a small, rapid movement of the eyelid. According to specialists, it does not affect vision and is usually triggered by fatigue and stress.
Experts say that these are mild tremors and go away without medical treatment. They can go away with enough sleep, reducing stress and caffeine consumption. However, if they get worse, consult your ophthalmologist immediately.
2. Blepharospasm
According to the National Eye Institute’s website, it involves blinking or other eyelid movements that are uncontrollable. They usually disappear spontaneously.
However, specialists clarify that people with benign essential blepharospasm can develop severe and chronic eyelid muscle contractions over the long term, so it is important to see a doctor in time if this symptom persists.
They also mention that this spasm occurs when the parts of the brain that control the eyelid muscles no longer function properly. On the other hand, the MSD Manual explains that it can also be caused by trichiasis (which consists of a misalignment of the eyelashes), the presence of a foreign body in the eye, dry eyes and sometimes by nervous disorders such as Parkinson’s disease.
3. Hemifacial spasm
According to the Mayo Clinic , this is a nervous system disorder. It involves the contraction of the muscles on one side of the face. It is usually caused by a blood vessel that touches or rubs against a facial nerve. Experts also say it can be caused by an injury to the facial nerves or a tumor, or by an unknown cause.
However, this is a multifactorial condition. Therefore, go to your trusted ophthalmologist or internist to perform the appropriate medical examinations and determine the exact cause of your problem.
