Definitions of Visual Impairment
Low Vision
● 20/70 acuity in the better eye after best possible correction
● Glasses cannot ‘fix’ everything!
Blindness
● 20/200 acuity in the better eye after best possible correction
or
● a visual field of 20 degrees or less
Facts of Blind/Visual Impairment
● 1-1000 people are visually impaired
● 1-10 000 people are blind
Functional Vision is how well an individual uses
the vision they have in given circumstances

Common Eye Disorders
Refractive Errors - Myopia, Hyperopia, Astigmatism
Glaucoma
Cataracts
Retinopathy of Prematurity
Albinism
Nystagmus
Optic Nerve Atrophy
Cortical Visual Impairment
How Vision Impairment AffectsDevelopment
● 80-90% of what most people learn is visual
● Vision is a unifying sense
● All areas of development are affected by vision loss:
■ Cognitive Skills development
■ Fine and Gross Motor Skills
■ Speech and Language Skills
■ Social and Play Skills

Educational Implications for students who are Blind and/or Visually Impaired
● Qualified Teachers of the Visually Impaired and Blind are needed in schools for successful education
● Courses offered as Additional Qualifications through Teachers’ Colleges
● Currently 3 part course: Teaching Students who are Blind Part 1, Part 2 and Specialist after achieving certification in braille
Expanded Core Curriculum (ECC)(Essential Skills for the Visually Impaired and Blind)
1. Compensatory Skills: braille, tactile, large print
2. Assistive Technology
3. Sensory Efficiency
4. Orientation and Mobility
5. Social Interaction Skills
6. Independent Living Skills
7. Recreation and Leisure Skills
8. Career Education
9. Self-Determination

Individual Education Plans (IEP)
● Legal document that outlines:■ Accommodations ■ Modifications ■ Alternative Programs (ECC)
● Accommodations for visual needs are determined through a Functional Vision Assessment and listed in three areas:
■ Instructional ■ Assessment■ Environmental
Factors that enhance visual functioning:
● Ensure glasses are worn and are cleaned regularly
● Ensure proper lighting● Reduce glare● Selective seating for best visual access● Reduce auditory distractions● Ensure visual aids are available and used properly● Position work at proper distance/angle

● Team planning well in advance
● Use multi-sensory approach
● Provide descriptive and consistent language
● Remember to allow more time
● Expect same quality not quantity
● Avoid large amounts of homework
General Classroom Considerations:
Considerations for Students with Low Vision:
● Provide alternate format materials for students
who have low vision (large print, auditory)
● Provide visually appropriate materials
● Provide a desk copy of notes and classroom
charts
● Avoid a lot of copying tasks
● Provide extra time

Visually Appropriate Materials Should:
● Be enlarged (as appropriate to student’s needs)
● Have good contrast
● Use bold colours
● Have simple text and pictures
● Have de-cluttered diagrams, pictures and maps, etc.
● Have only diagrams and pictures that are necessary
for understanding

● Provide alternate format materials (braille, tactile and
auditory)
● Provide concrete and tactually appropriate materials
● Exploration of math manipulative materials prior to using
them for math concept development
● Use of concrete materials into higher grades to ensure
student comprehension, transition slowly…
concrete --> semi-concrete --> semi-abstract --> abstract
Considerations for Students who are Blind:
Considerations for Students who are Blind:
● Provide a desk copy of notes and classroom charts
● Avoid a lot of copying tasks
● Use of uncontracted vs contracted Unified English Braille
(UEB)
● Teach math braille code (the math code is part of UEB) to
the student at the same time as peers
● Provide extra time (timetabled into the day)
● Pre and post teaching
