Vision screening & 20/20 sight
Doesn’t tell us if you or your child:See clearly all day longFocus between a book and a
blackboardSee single not doubleRead without getting a headache Has healthy eyes
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
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
Comprehensive Exams
For infants at 6 months
For ages 2 to 5 years at 3 years
For ages 6 to 18 every year For ages 18 to 60 every 2
years For ages 61+ every year
Infants key to the world is vision

Infant Vision
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
What you can do for infants
Use night light Change position of crib and infant in
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.
Infant eye alignment problems
Preemies can have retinopathy of prematurity
See pediatric ophthalmologist to be sure Strabismus or misalignment becomes lazy
eye Nystagmus results from congenital cataracts
AOA member ophthalmologists offer a Comprehensive eye exam at NO COSTInfantSEE available for first year of life

Every year from 6 to 18 years of age 10% of preschoolers and 25% of
children from grade K thru 6 have vision deficiencies
School is more difficult if you can’t see
Games are not fun if you can’t see
Childrens’ Vision
What to look for: Holding books unusually close to read Loosing their place often while reading Squinting or frequent eye rubbing Headaches, tearing, or closing one eye
to read Low grades and avoiding close vision
activities
Childrens’ Vision
Almost 80% of what your child learns is visual
The state of the eyes encompasses:Eye health, visual acuity and refractive
errorThe functioning of the eyes encompasses:Focusing, eye tandem, and movementVisual perception, hand-eye
coordination and visual memory
Children's vision skills
RecognitionComprehension Visual
perceptionRetention skillsChanges in vision can occur without noticeUnderperformance in school or sports can
beA sign of vision changes
Childrens’ Vision and computers
25-30% of computer using children require corrective eyewear to work safely
The computer demands fine motor skills
Children have limited self-awarenessChildren are very adaptableChildren are smaller than adults
Young adults eye health
Most common problems are stress and injury
Protect your eyesEat healthy Wear sunglasses
outsideDon’t smoke Get regular eye
examsExercise
Vision over Forty
Presbyopia affects most of us as we age
The most at risk are:Those with Diabetes or high blood
pressureFamily history of macular
degenerationGlaucoma
Vision over Forty
High stress jobs are visually taxingMany medications have ocular side effectsHigh cholesterol, thyroid conditionsAnxiety and depression
Vision changes over forty
Retina becomes less sensitive to light
The eye’s lens becomes less elasticEye’s lens may become cloudyEyes become drierVision may be populated with bright
points of light, blurred images or dull colors
Signs to watch for
Fluctuating visionSeeing floaters and flashesLoss of peripheral visionSeeing distorted images Could be signs ofRetinal detachmentGlaucomaAge related macular degeneration
Vision over sixty
Vision changes are now permanent Get yearly eye exams to detect disease earlyDriving requires extra caution to stay safeLimit driving to daylight and use extra cautionTake a driving course for seniorsAvoid wide frames which can block side vision
Vision over sixty
Most common causes of low vision are:
AMD, glaucoma, retinal detachment, stroke
250,000 new cases each yearBecause population aging
prevalence and incidence will double over next 2 decades
Vision over sixty
Age related Macular Degeneration (AMD)Major cause of blindness in 60+ groupAffecting 30% of all people 75+ years of age
Smoking doubles risk of AMDIncrease in consumption of omega 3 significantly reduced AMD prevalence
Vision over sixty
Over 4 million Americans have low vision
68% of them are over 60Low vision is impaired vision which
can’t be fully restores through lenses or surgery
