SIGHT VS VISION
Sight is the simple response to light & brightness
Vision is a sensory, motor, perceptual process
Vision is the ability to identify, interpret, and understand what is seen
![Page 7: Lc Pp2](https://reader036.vdocuments.site/reader036/viewer/2022062406/558868b9d8b42a61308b45d5/html5/thumbnails/7.jpg)
Visual Acuity
What does 20/20 and 20/200 mean?Top number denotes a test distance
of 20 feetThe bottom is the distance a person
with 20/20 vision can read the letter20/200 sees at 20 feet what a person
with normal acuity sees at 200 feet.

Vision Screening Limitations
Screenings evaluate distance visual acuity NOT :
How eyes focus at near How well eyes work together General health of eyes
PLUS Volunteer screeners have limited
knowledge of vision and eye health

Babies learn to see over time like walking Their eyes are uncoordinated and wonder They can only focus 8 inches away Newborns only see in black and white Depth perception appears at 5 months Babies develop from head down Eyesize starts at 65% of adult

it Alternate sides with each feeding Keep reach and touch toys within
focus range Mothers keep same hair style for
recognition

Infant Vision Development
Infants start to see color during 1st month They start to follow moving objects 2-3 mo. Visual acuity improves from 20/400 at birth
to20/25 at about 6 mo. At 6 – 12 mo hand eye coordination
improves Depth perception, eye teaming and body
eye coordination are quite good by 10-12 mo.
Eye color changes from blue to adult color.
