Curious about Eye Misalignment? Understand Strabismus and Squinting

Have you ever noticed someone whose eyes don't seem to align correctly? Maybe you've wondered why they squint or have a wandering eye. The condition responsible for these eye misalignments is called strabismus, commonly known as "squinting.”

What is Strabismus?

Strabismus is a visual condition where the eyes are misaligned and do not work together. In normal vision, both eyes focus on the same object and send coordinated signals to the brain. However, in individuals with strabismus, one eye may turn inward, outward, upward, or downward while the other maintains its correct position. This misalignment can occur constantly or intermittently, depending on the individual and the severity of the condition.

Causes of Strabismus:

Strabismus can develop due to various factors, primarily occurring during childhood. Here are some common causes:

  1. Weak eye muscles: If the muscles responsible for controlling eye movement are weak or imbalanced, it can result in a misalignment of the eyes.

  2. Nerve issues: Problems with the nerves that control eye movement can disrupt eye coordination, leading to strabismus.

  3. Family history: Strabismus often runs in families. If a parent or sibling has the condition, there is a higher chance of developing it.

  4. Refractive errors: Untreated nearsightedness, farsightedness, or astigmatism can contribute to the development of strabismus.

Signs and Symptoms

  • Misalignment of the eyes: The most noticeable sign of strabismus is the misalignment of the eyes. One eye may turn inward (esotropia), outward (exotropia), upward (hypertropia), or downward (hypotropia).

  • Squinting: Squinting is a common symptom observed in individuals with strabismus. It is a natural response that helps the misaligned eyes focus better, reducing double vision.

  • Double vision: Some people with strabismus may experience double vision. This occurs when the misaligned eyes send different visual information to the brain, leading to the perception of two images instead of one.

  • Difficulty with depth perception: Strabismus can affect depth perception, making it challenging to accurately judge distances or perceive the relative positions of objects in space.

Impact on Vision and Daily Life

Strabismus goes beyond affecting the appearance of the eyes. It can have significant impacts on visual function and daily life. Some of the effects of strabismus include:

  • Poor depth perception: Strabismus can impair the ability to perceive depth accurately. This can affect tasks such as judging distances or playing sports that require accurate depth perception.

  • Reduced visual acuity: Misaligned eyes can lead to reduced visual acuity in the affected eye or both eyes. This can result in blurry or unclear vision, making seeing objects or reading the fine print challenging.

  • Difficulty with binocular vision: Strabismus disrupts eye coordination, making it challenging to achieve binocular vision. Binocular vision allows us to use both eyes together, enhancing depth perception and visual clarity.

  • Academic challenges: Children with strabismus may face difficulties in school. Reading and focusing on written materials can be particularly challenging, affecting academic performance and learning.

  • Impact on self-esteem and social interactions: The noticeable appearance of strabismus may affect a child's self-esteem and social interactions. They may feel self-conscious or experience peer teasing or bullying, leading to social and emotional challenges.

Diagnosis and Treatment

If you suspect that you or your child may have strabismus, it's crucial to seek the expertise of an eye care specialist. They will conduct a thorough examination, which may involve various tests to assess visual acuity, eye movements, and alignment. They can gather vital information to diagnose you by reviewing your medical history. Treatment options for strabismus can vary depending on the individual and the severity of the condition. Here are some possible approaches:

  • Eyeglasses or contact lenses: Correcting refractive errors can help alleviate or reduce misalignment.

  • Vision therapy: Special exercises and activities can be prescribed to strengthen the eye muscles and improve coordination.

  • Eye patches or eye drops: In situations where one eye is weaker than the other, covering the stronger eye or using drops to blur vision can encourage the weaker eye to strengthen and align properly.

  • Surgery: In some instances, surgical intervention may be necessary to realign the eye muscles and correct the misalignment.

Seeking Professional Help

If you or your child exhibit signs of strabismus or experience eye misalignment, don't hesitate to consult a qualified eye care specialist. They can accurately diagnose and recommend the most appropriate treatment options to improve eye alignment and visual function.

Understanding strabismus and squinting helps demystify the condition and promote awareness and understanding. Early detection and intervention are vital to effectively managing strabismus and ensuring optimal visual development. So, if you have any concerns, contact an eye care professional and embark on a journey toward better eye alignment and visual health!


In conclusion, strabismus, or eye misalignment, is a condition that requires attention and proper treatment. It can affect a person's vision, depth perception, and overall well-being. If you or your child are experiencing symptoms of strabismus, it is crucial to seek help from a specialized eye care provider. Early intervention and personalized care can help restore proper eye alignment, improve visual function, and enhance the overall quality of life.
