Introduction
In general, eye twitching usually refers to nystagmus. It may be caused by genetic factors, eye strain, vitreous opacities, refractive errors, keratitis, and other conditions. After identifying the underlying cause, symptomatic treatment can be carried out under the guidance of a professional doctor. In any case, individuals with nystagmus should avoid eye fatigue. Wearing windproof and UV-protective glasses is recommended to reduce eye irritation.

Under normal circumstances, eye twitching generally refers to nystagmus. This may be caused by genetic factors, eye strain, refractive errors, vitreous opacities, keratitis, and other conditions. It is recommended to seek medical attention promptly; once the underlying cause is identified, symptomatic treatment can be carried out under the guidance of a qualified physician. Specific analyses are as follows:

1. Genetics

Inherited factors may lead to congenital nystagmus, which is considered a normal condition. If there are no other associated symptoms, special treatment is usually not required.

2. Eye Strain

Prolonged use of the eyes or staying up late may impair ocular blood circulation, leading to nystagmus accompanied by fatigue. Applying warm compresses can help improve blood flow in the eyes and relieve symptoms. Additionally, maintaining adequate sleep, avoiding prolonged熬夜 (staying up late), and gently massaging acupressure points around the eyes to relax eye muscles can effectively alleviate eye twitching.

3. Refractive Errors

Refractive errors occur when the eye cannot properly focus light, such as in myopia (nearsightedness). As the condition progresses, symptoms like flashes of light, floaters, or shaky vision may appear. Corrective lenses or refractive surgery can refocus light onto the retina and thereby improve these symptoms.

4. Vitreous Opacity

Vitreous opacity is often caused by trauma and may result in blurred vision, decreased visual acuity, and nystagmus. It is recommended to seek treatment at a reputable hospital, possibly through surgical methods such as full femtosecond laser surgery, half femtosecond laser surgery, or excimer laser surgery.

5. Keratitis

Keratitis is an inflammatory response caused by weakened corneal defenses, allowing external pathogens or systemic diseases to invade corneal tissue. It may lead to eyelid spasms, a sensation of shaking when viewing objects, and varying degrees of vision loss and blurriness. Treatment may include medications such as erythromycin eye ointment, tobramycin eye drops, or norfloxacin eye drops, as prescribed by a doctor.

In summary, individuals experiencing nystagmus should avoid eye strain. Wearing windproof and UV-protective glasses can help reduce eye irritation.
