Learners Who are blind and Visually Impaired

Learners who are blind and visually impaired. Vision impairment occurs due to a myriad of causes, such as:

  • Congenital conditions
  • Eye Injury
  • Eye Diseases
  • Brain Trauma
  • Multiple sclerosis
  • Diabetes

Legally Blind

A person is diagnosed legally blind if their corrected vision is less than 20/200, as they only see at twenty feet what others see at 200 ft or have side vision of no more than 200 degrees diameter or 10 degrees radius.  A person is condidered visually impaired when corrected vision is no better than 20/70.

Most legally blind people have some measurable vision and light perception.  A student who is blind is able to read and drive with special glasses.  More importantly some have 20/20 vision (see things as though they looking through a straw). They use guide dogs and a cane and see large objects but struggle with reading. The term “blindness” should be reserved for people with complete blindness.  the preferred term is “visually impaired” for people with various grades of vision.

At Action we have students who are totally blind, but adaptations and accommodations needed for blind people can be applied to all students and vision impairment. Most students who are visually impaired use the following accommodations:

  • Books on tape
  • E-text
  • Voice synthesizing computers
  • Braille
  • Optical scanners
  • Screen readers

By the time blind students leave us they have mastered techniques for dealing with visual materials.  Our students use a combination of tools, including:

  • Screen readers
  • Braille materials
  • Software for speech to text

Thanks to technology available, we are able to train blind students to perform in the workplace in a confident manner. Learners who are blind and visually impaired prefer their own notes using computers rather than Braillers.
