Squint: What & Why

Published on June 7, 2016 by HTC Team

What is squint?

In layman’s words, a squint can be described as “have eyes that look in different directions”. Thus, a person having squint is commonly called cross-eyed.

Normally, when a person looks at something, both eyes look at the exact same spot. Sometimes, there may be abnormal alignment of eyes which can cause one eye to look at a deviated position from the other eye. This condition is called squint or Strabismus.

Squint can happen in adults as well as in children


  1. Incorrect balance of eye muscles

Any imbalance in eye muscles can cause squint. This is one of the most common causes of squint.

  1. Any condition that causes vision in one eye to be less than vision in the other eye can lead to squint. This is one of the most common causes of squint.
  1. Refractive error

Myopia (minus power/short-sightedness) or hypermetropia (plus power/ long-sightedness) may cause squint. This is the major cause especially in children.

  1. Faulty nerve signals to eye muscle
  1. Unclear media for light to pass through

Opaque outer area of eye, opaque conducting lens, optic nerve (nerve conducting the impulse from eye to brain) malfunction: such abnormalities may cause a distorted vision in one of the eyes hence causing vision in one eye to be different than that of the other.
