Understanding the Terms: Strabismus or Squint?
When people talk about strabismus vs squint, it’s important to know they’re referring to essentially the same condition: a misalignment of the eyes. The term squint vs strabismus simply reflects different ways of describing the same problem.
The word “squint” is commonly used in everyday conversation, particularly in countries like India and the UK, to describe eyes that do not appear straight. “Strabismus,” on the other hand, is the medical and clinical term used by ophthalmologists and eye care professionals.
What Happens in Strabismus and Squint
In a healthy pair of eyes, both eyes move together and focus on the same point at the same time. This coordination allows the brain to merge images from both eyes into a single, clear, three-dimensional picture—a process called binocular vision.
In strabismus (squint), this coordination breaks down. One eye may turn inward (esotropia), outward (exotropia), upward (hypertropia), or downward (hypotropia), while the other eye looks straight ahead. The misalignment may be constant or intermittent, and it can affect one or both eyes.
Each eye has six extraocular muscles that control eye movement. When these muscles fail to work in harmony—due to nerve problems, muscle weakness, refractive errors, or brain-related issues—the eyes lose alignment. As a result, the brain receives two different images, which can lead to:
- Double vision (diplopia)
- Blurred or distorted vision
- Eye strain or headaches
- Difficulty with depth perception
In young children, the brain may suppress the image from the misaligned eye to avoid double vision. Over time, this suppression can lead to amblyopia, also known as lazy eye, where vision in the affected eye fails to develop normally.
Exploring the Difference Between Squint and Strabismus
So what is the difference between squint and strabismus? In fact, there is none in the definition: both refer to the same eye-alignment condition. The phrase is more about semantics, i.e. medical vs layman usage. “Strabismus” is the medical term, while “squint” is more commonly used in general conversation.
In both cases, the condition describes a misalignment of the eyes, where one or both eyes may turn inward, outward, upward, or downward instead of looking straight ahead together. This misalignment can be constant or intermittent and may affect one eye or alternate between both eyes. Squint or strabismus can occur in children or adults and may be present from birth or develop later due to nerve damage, muscle imbalance, injury, or underlying medical conditions. Early diagnosis and appropriate treatment are important to prevent vision problems such as lazy eye (amblyopia), double vision, or reduced depth perception.
Common Causes of Squint or Strabismus
Strabismus can develop at any age, but it is most commonly diagnosed in early childhood. Some common causes include:
- Uncorrected refractive errors (especially farsightedness), where the eyes struggle to focus clearly, leading to misalignment
- Muscle imbalance or weakness that affects coordinated eye movement
- Eye injuries or trauma that damage eye muscles or nerves
- Neurological conditions that interfere with brain–eye communication
- Genetic or family history increases the likelihood of developing a squint
- Premature birth or low birth weight can affect visual development
- Systemic conditions such as cerebral palsy or Down syndrome, often associated with muscle and nerve control issues
In adults, strabismus may develop suddenly due to neurological issues like stroke, thyroid eye disease, or nerve palsies, and often presents with noticeable double vision, eye strain, headaches, or difficulty focusing. Early evaluation is essential to identify the underlying cause and prevent long-term visual complications.
Diagnosis and Management: Getting Aligned Again
Early diagnosis of strabismus is essential, especially in children, to prevent permanent vision loss and improve eye coordination. An ophthalmologist will perform a detailed eye examination, which may include:
- Visual acuity testing
- Eye alignment and movement evaluation
- Refraction testing
- Dilated eye examination
Treatment for squint or strabismus depends on the cause, age of the patient, and severity of misalignment. Common treatment options include:
- Corrective glasses to address refractive errors
- Patching therapy to strengthen a weaker eye
- Vision therapy or eye exercises to improve coordination
- Botulinum toxin (Botox) injections in selected cases to relax overactive muscles
- Squint surgery, where eye muscles are adjusted to restore proper alignment
The Importance of Awareness and Early Action
Strabismus is not just a cosmetic issue. Misaligned eyes can affect:
- Visual development
- Academic performance in children
- Confidence and self-esteem
- Social interactions and quality of life
Unfortunately, squint is sometimes ignored under the assumption that a child will “outgrow it.” This misconception can delay treatment and lead to irreversible vision problems. Early intervention improves outcomes significantly and, in many cases, can restore normal vision and eye coordination.

FAQs
What is the difference between strabismus and squint?
Strabismus and squint mean the same, but “strabismus” is the medical term, and “squint” is commonly used.
Are squint and strabismus the same?
Yes, squint and strabismus are identical terms referring to eyes that do not align properly.
Is squint another name for strabismus?
Yes, “squint” is the commonly used name, while “strabismus” is the clinical medical term.
Are lazy eye and squint the same?
No, lazy eye (amblyopia) results from reduced vision, while squint involves eye misalignment.
