What causes constant eye twitching?

Constant eye twitching may be caused by factors such as eye strain, negative emotions, refractive errors, conjunctivitis, or keratitis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Eye Strain

Prolonged use of the eyes—such as staring at electronic devices like computers or smartphones—can lead to eye strain, causing the eye muscles to remain tense for extended periods, which may result in eye twitching. It is advised to perform regular eye relaxation exercises, such as gazing into the distance or closing the eyes to rest. Additionally, maintaining sufficient sleep can help alleviate these symptoms.

2. Negative Emotions

Excessive mental stress, anxiety, or similar emotional states may affect the stability of the nervous system, leading to eye twitching. It is recommended to adjust one's mindset, maintain a positive and optimistic attitude, and engage in moderate physical activity or relaxation exercises to relieve psychological stress and improve symptoms.

3. Refractive Errors

Conditions such as myopia (nearsightedness) or hyperopia (farsightedness) may contribute to this issue. If individuals with refractive errors wear glasses with incorrect prescriptions, it may alter the tension of the eye muscles and lead to muscle twitching. It is advisable to undergo a new eye examination and wear properly corrected eyewear to help resolve these symptoms.

4. Conjunctivitis

This may be related to viral infections or exposure to smoke and dust. Local inflammation can irritate the eye muscles, causing twitching, often accompanied by redness and swelling of the eye. Patients are advised to follow medical instructions and use medications such as chloramphenicol eye drops, ganciclovir eye drops, or ofloxacin eye drops for treatment.

5. Keratitis

This condition may be associated with microbial infections or underlying diseases such as diabetes. The inflammation can stimulate the eye muscles, resulting in twitching, often accompanied by eye pain. Patients should follow their doctor’s instructions and use medications such as levofloxacin eye drops, acyclovir eye drops, or natamycin eye drops for treatment.

In daily life, individuals should practice healthy eye habits, avoid prolonged continuous eye use, drink plenty of warm water, ensure adequate sleep, and consume eye-healthy foods such as carrots and blueberries, which are beneficial for overall health.
