Essay / Research Paper Abstract
8 pages in length. Depth perception is what keeps humans from colliding with other objects in their path; without the proper development of depth perception, an individual's ability to judge proximity to another object is significantly impaired. Bibliography lists 7 sources.

to another object is significantly impaired. Early visual development is both normal and rapid throughout the infants initial six months all the way into the first ten years of
life. Especially sensitive to various visual conditions and interference, young children must be monitored on a regular basis in order to assess any potential developmental problems with depth perception.
Indeed, myriad situations can occur where vision formation is detrimentally impacted, such as amblyopia (central visual system defect), which influences depth perception. Early detection are treatable, however, "the
potential for correction and normal visual development is inversely related to age" (Mills, 1999, p. 907). Critical to early detection and treatment is not depending solely upon clinical signs
to indicate a potential problem, inasmuch as many problems are asymptomatic; instead, effective and regular vision screening is the only accurate method of detection. II. INFANCY Newborn babies do
have vision, yet it is significantly limited in all aspects. As the infant develops during the subsequent six months, visual acuity is vastly improved upon by way of "rapid
anatomic development in the eye and central visual pathways parallels" (Mills, 1999, p. 907). This progressive retina and retinal photoreceptor maturation, along with myelination of optic nerves and tracts,
and augmentation of the visual cortex synaptic density, enables a six-month-old infants visual acuity to attain the equivalent of Snellen 20/30. From this point forward, however, development decreases upon
an overall basis, while myelination helps the central visual pathways maintain progress all the way up through approximately four years of age. Additionally, further visual cortex development continues all
through the childs first ten years (Mills, 1999). Depth perception is related to the development of binocularity, which allows both eyes to perceive an object at the same time, and
