A child's visual system develops actively from birth until approximately 7 to 8 years of age. If an eye alignment defect or severe refractive error goes uncorrected during this critical window, the brain may permanently ignore input from that eye, resulting in Amblyopia (Lazy Eye).

What is Amblyopia (Lazy Eye)?

Amblyopia occurs when the brain favors one eye due to unequal vision or crossed eyes (strabismus). Patching the stronger eye for a few hours daily forces the brain to rewire neural connections to the weaker eye, restoring binocular vision.

The 20-20-20 Rule for Digital Eye Strain

Increased smartphone and tablet usage has led to soaring childhood myopia. Enforce the 20-20-20 rule: every 20 minutes, have your child look at an object 20 feet away for at least 20 seconds, and ensure at least 90 minutes of outdoor daylight play daily.
