If it is not treated soon, the condition will permanently damage the vision. When left untreated for long, the brain of the maturing child will start to ignore the images coming from the defective eye leading to permanent vision defect. (1)

What Causes Lazy Eye In Children?

Amblyopia develops when one of the eyes of the child has more focus than the other. The eye starts to ignore the blurry images if left untreated for a long time and the condition of the lazy eye and its vision deteriorates. Some of the immediate factors that give rise to such a situation are: (2)

  1. Strabismus: When eyes are not aligned properly, which results in crossed or wandering eyes, can weaken the focus of one of the eyes. The brain suppresses the blurred images captured by the wandering eye and soon, the vision in that eye is almost lost.
  1. Astigmatism: Extreme far-sightedness or near-sightedness can result in the misalignment of focus by both eyes. The image of the focused eye is given prominence and the hyperopic or myopic eye’s blurry vision is ignored by the brain leading to lazy eye in the child.
  1. Droopy Eyelid: Apart from Strabismus and Astigmatism, issues such as anatomical and structural deformities can also result in a lazy eye. If the eyelid of one of the two eyes is a droopy eyelid, then it is sure to block vision in that eye, resulting in a lazy eye.
  1. Cataract: Formation of cataract on the retina of any of the two eyes of the child also causes vision blockage. The brain refuses to acknowledge the blurred and out of focus images of the cataract-eye leading to the condition of lazy eye.
  1. Anisometropia: The child may have different vision strengths in their eyes, which result in amblyopia in children.
  1. Genetics: Family history and genes play an important role in the development of amblyopia in kids. As amblyopia tends to run in families, children who share a family history can be at a risk of developing it.
