Why Does My Child Constantly Blink His Eyes?

As a parent, you may notice that your child blinks his eyes frequently or excessively, and wonder if this is a sign of a problem.

While occasional blinking is normal and necessary for keeping the eyes moist and clear, persistent blinking can be a symptom of various conditions that affect the eye muscles, nerves, or brain.

In this article, we will explore some of the common causes of excessive blinking in children, and suggest some ways to address them.

Common Causes of Excessive Blinking in Children

1. Dry Eyes

If your child’s eyes are not producing enough tears or are evaporating too quickly, he may blink more often to compensate for the discomfort.

Dry eyes can be caused by many factors, such as allergies, certain medications, environmental irritants, or medical conditions like Sjogren’s syndrome or rheumatoid arthritis.

To treat dry eyes, you can use artificial tears or lubricating eye drops, avoid rubbing the eyes, use a humidifier to add moisture to the air, or consult an ophthalmologist if the symptoms persist.

2. Eye Infections

If your child’s eyes are red, swollen, or have a discharge, he may have an eye infection like conjunctivitis or blepharitis.

These infections can be caused by bacteria, viruses, or allergies, and can spread easily if not treated properly. In addition to excessive blinking, your child may also complain of itching, burning, or sensitivity to light.

To treat eye infections, you should clean the affected area with warm water and a clean cloth, avoid sharing towels or eye makeup, use antibiotic or antiviral eye drops or ointments as prescribed by a doctor, and follow good hygiene practices.

3. Eye Strain

If your child spends too much time staring at a screen, reading in dim light, or doing close-up work without taking breaks, he may strain his eye muscles and cause them to twitch or blink involuntarily.

Eye strain can also lead to headaches, neck pain, and blurry vision. To prevent eye strain, you can encourage your child to take frequent breaks, adjust the screen or book distance to a comfortable level, use proper lighting and ergonomics, and engage in outdoor activities that promote eye relaxation.

4. Tourette Syndrome

If your child has Tourette syndrome, a neurological disorder that affects the control of movements and speech, he may have a tic that involves blinking or eye rolling.

Tics are repetitive, sudden, and involuntary movements or sounds that can be triggered by stress, excitement, or fatigue. While tics can be distracting or embarrassing, they are not harmful or contagious, and usually improve with age.

To manage tics, you can avoid drawing attention to them, teach your child relaxation techniques, provide a supportive and understanding environment, and seek medical advice if the tics interfere with daily activities or cause emotional distress.

How can I tell if my child has eye strain?

Eye strain is a common condition that can affect children who spend long hours on digital devices, doing near work, or reading in poor lighting conditions. If your child has eye strain, he may experience some of the following symptoms:

  1. Eye discomfort: Your child may complain of sore, tired, or burning eyes, especially after prolonged use of screens or close-up work.
  2. Headaches: Your child may develop headaches, especially around the forehead, temples, or back of the head, which can worsen with eye movement or light exposure.
  3. Blurred vision: Your child may have difficulty focusing on objects or reading text, and may see double or fuzzy images.
  4. Dry eyes: Your child’s eyes may feel dry, itchy, or gritty, and may become red or watery.
  5. Sensitivity to light: Your child may be more sensitive to bright lights or glare, and may squint or close his eyes frequently.
  6. Neck or shoulder pain: Your child may experience muscle tension or stiffness in the neck, shoulders, or upper back, which can be related to poor posture or eye strain.

If your child has one or more of these symptoms, it’s important to take a break from the activity that is causing the eye strain and rest the eyes for a while. You can also encourage your child to adopt healthy eye habits, such as:

  • Taking frequent breaks from digital devices or close-up work (e.g., every 20 minutes, look away from the screen and focus on a distant object for 20 seconds)
  • Using proper lighting and ergonomics (e.g., avoiding glare, adjusting the screen angle and height, maintaining a comfortable distance and posture)
  • Practicing eye exercises or relaxation techniques (e.g., looking up and down, side to side, in a circular motion, palming the eyes with warm hands)
  • Spending more time outdoors and engaging in physical activities that promote eye health.

If the symptoms persist or worsen despite these measures, you should consult an eye doctor who can perform a comprehensive eye exam and recommend appropriate treatment options.


Excessive blinking in children can be a sign of various underlying conditions, such as dry eyes, eye infections, eye strain, or Tourette syndrome.

By identifying the cause and addressing it promptly, you can help your child feel more comfortable and confident, and prevent potential complications.

If you have any concerns about your child’s eye health, you should consult a qualified eye doctor who can perform a thorough examination and provide personalized recommendations.
