Maturation of the retina and retinal photoreceptor (rod and cone cells), myelination of the optic nerves and tracts, and increased synaptic density of the visual cortex are the anatomic substrates that allow visual acuity to reach the equivalent of Snellen 20/30 by six months of age.2The visual system develops at a slower rate after six months of age.
Myelination continues to increase in the central visual pathways until about four years of age, and development of the visual cortex continues throughout the first decade of life.

Normal visual development is rapid during the first six months of life and continues through the first decade.
Fewer cells will be responsive to the affected eye in the visual cortex and lateral geniculate, and the cells related to the involved side will be smaller and have fewer synapses.
While amblyopia may under certain circumstances occur bilaterally, it appears that relative competitive effects between the eyes accelerate the development of amblyopia when the opposite eye is unaffected.Your best defense is to have regular checkups, because eye diseases do not always have symptoms.Early detection and treatment could prevent vision loss.The eye movement system is incompletely functional at birth but develops rapidly in parallel with the development of vision.Binocularity (the ability to perceive vision from both eyes simultaneously) and stereopsis (integration of the images from the two eyes to produce a single image with depth perception) can develop only if the eyes are fairly precisely aligned.In addition, as the infant's interest in exploring the visual environment increases, the need for voluntary eye movements increases.
