The visual system begins to develop in utero at approximately the 22nd day of fetal life (Telang & Dweck, 1989). However, the first week of life, babies still aren't able to see much detail and it takes several months for your child's vision to develop fully (Heiting, 2017).
Fun Facts:
Babies' eyes are comparatively large, reaching adult proportions at the age of two.
The iris is slate gray because of the absence of stromal pigmentation; normal adult color develops fully by the end of the first year.
The pupil reacts to light at birth, but it is sluggish.
Blink to threat is not present until 2 to 5 months after full term birth.
Tears are not present with crying until 1-3 months
Visual acuity of a full term infant is approximately 20/400 at birth.
Dolls eye movements (the eyes lagging behind the turning of the head from side to side) are normally present at 2-3 months of age when the child can fixate well.
Eye movements are not well coordinated until 3 to 6 months of age.
By 6 months old, the eyes should be well coordinated.
20/20 is normally achieved by 2 years of age.
Myopia is uncommon in infants, but tends to appear between 6-9.
Children tend to be slightly hyperopic because of the configuration of the eye until adolescence.
The eye continues to develop visual synapses in the visual cortex until 10 years of age.
