According to a recent study by the National Institutes of Health, neither trained nurses nor
trained lay people using the best screening tests possible were able to identify almost one-third of
even the most prevalent vision disorders in children in the study. Disorders such as amblyopia,
strabismus, and refractive errors were missed during the study’s screening process.

A report by the National Eye Institute states, "In children, visual impairment is associated with
developmental delays and the need for special educational, vocational, and social services, often
beyond childhood into adulthood."

Objective:
• Primarily to educate parents and teachers on vision problems
that can hinder children's school performance, interrupt their
lives, and limit their futures.
• Teach basic definitions of nearsightedness (myopia) and
farsightedness (hyperopia)
• Review signs and symptoms that educators can use when
evaluating a students vision
• Discuss the issues related to hidden vision problems
• Educate on the importance of efficient and effective vision
screenings as well as comprehensive eye exams by an optometrist
• What resources are available to teachers and parents?
Basic Definition of Terms
•
Myopia – Also known as nearsightedness or short-sightedness, is a refractive defect of
the eye, where the person affected usually can see nearby objects clearly but distant
objects appear blurred.
•
Hyperopia - Also known as farsightedness or longsightedness, is also a refractive
defect of the eye causing difficulty to focus on near objects.
•
Amblyopia - Also known as “lazy eye,” amblyopia is reduced vision in a healthy eye.
Vision development is impaired when eyes do not focus equally or maintain proper
alignment. The brain ignores the information from the less favored eye. In either case,
if this condition persists, the weaker eye will not develop normally.
•
Strabismus - A misalignment of the eyes where the eyes don't point at the same object.
Crossed eyes (esotropia) is one type of strabismus; "wall-eyes" (exotropia) are another.
The exact cause is unknown, but appears to be a problem with the eye muscles.
Strabismus can affect depth perception.
Learning Related Vision Problems
• Eye Teaming
• Tracking skills-or the ability to control the fine eye movements required to
follow a line of print, are especially important in reading. Children with
tracking problems will often lose their place, skip or transpose words, and
have difficulty comprehending because of their difficulty moving their eyes
accurately.
•
Focusing-If a child is struggling with his focusing system, print on the page will often
look like this:
Vision Screenings Currently in Place
• Most elementary schools do have vision and hearing screening in place, but
several do not
• These screening tests are ran normally by parent volunteers that are not
educated with a background in eye care.
– Screening tests for distance vision only and children that are found with vision
over 20/50 are sent to the school nurse for a secondary evaluation. (if a school
nurse is present)
• The nurse then has the option to send a letter home urging parents to have
the child’s eyes tested by an eye care professional, but follow up is not
mandated
• Therefore, if near vision is not tested any child who is having difficulty
learning to read will go unnoticed
• In conclusion, screenings are designed to alert parents to the possibility of a
visual problem, but not take the place of a visit to an eye care practitioner.
Sometimes screenings are helpful, but they can miss serious vision problems
that your eye care practitioner would catch.
Check-list of Signs and Symptoms

Problems with vision screenings
•
•
Children can have 20/20 eyesight meaning ‘normal’ distance vision and still have
vision problems in other areas (Scheiman & Rouse, 2006)
School screenings don’t check to see if children can coordinate both eyes as a team,
track print across a written page without losing their place, or comfortably adjust focus
when looking from their desk to the chalkboard. (Kemper, 2003)
– One study found that 11.3% of children who passed a vision screening were found to have a
vision problem in need of correction (Logan and Gilmartin, 2004).
– Another problem with school or pediatrician screenings is that sometimes no follow-up
occurs even when a vision problem is detected.
– According to one study, 50% of parents were unaware two months later that their child had
failed a vision screening (Flanagan and Jackson, 2003).
– In another study, 80% of the kindergarten-age children examined who were found to have a
vision problem had visited a primary care physician in the past 12 months, but fewer than
20% had been told to see an eye doctor (Flanagan and Jackson, 2004).
– Another study found that when a 5- or 6-year-old failed an initial vision screening, the
average delay before evaluation by an eye care professional was more than four years (Arias,
2004).
Why is this a educational problem?
• Children who are struggling with undetected vision problems
often fail to consistently progress in school
• Vision plays a vital role in the reading process
• For succes in school, children must have other equally important
visual skills besides their sharpness of sight, or visual acuity.
– They must be able to coordinate their eye movements as a team.
– They must be able to follow a line of print without losing their place.
– They must be able to maintain clear focus as they read or make quick
focusing changes when looking up to the board and back to their desks.
– They must be able to interpret and accurately process what they are
seeing.
– If children have inadequate visual skills in any of these areas, they can
experience great difficulty in school, especially in reading.

Solution?
• Kentucky is the first state to require mandated eye exams prior
to entering elementary school
– Controversy in funding and procedures
• 34 states provide vision screening guidelines and 15 states require
vision screening of at least some of their preschool-aged
children, but no follow-up procedures are in place (Kemper,
2003)
• Oregon is one of nineteen states that have NO requirement for
children to receive preventive vision care before starting school
or during the school year.
Resources
• Vision Service Plan (VSP) is a nationwide insurance company
dedicated to high quality eye care. VSP has organized two
extremely important programs called “Sight for Students” and
“Get Focused.”
– Sight for Students is a VSP charity that provides free vision exams and
glasses to low-income, uninsured children. The program operates
nationally through a network of community partners who identify
children in need and VSP network doctors who provide the eyecare
services (https://www.vsp.com/about/html/community.jsp#).
– VSP helps over 50,000 children each year help the valuable eye care
services they need.
– Get focused is a classroom curriculum designed to help teachers and
parents educate their students on the importance of eye exams.
• The program has curriculum activities that educate students on the basic
anatomy of eye, cooperative learning activities as well as the importance of
eye safety
Resources
• The Oregon Foundation for Vision Awareness
(OFVA), is a local non-profit agency whose mission
and goal are to provide education and charitable
services for children who have eye care needs
(http://www.ofva.org/ofva/).
– The OFVA strives to connect Oregon’s children with
essential eye care services, which has been under-utilized by
Oregon’s elementary schools.

Resolution
• In today’s society, teachers have to go above and
beyond the call of duty by not only teaching
their curriculum, but also dealing with social and
behavioral issues. By mandating eye exams prior
to elementary school we would be reducing
several obstacles like cognitive, emotional and
behavior problems. In the end, we would be
giving our children a head start on learning and
allowing our teachers to do what they do best,
teach!!
