Vision

An article from Learning-Related Vision Problem from the website, All About Vision  introduces vision problems that have the potential to affect academic and reading performance.  Types of Learning-Related Vision Problems include Eye health, refractive problems, Functional vision problems, and Perceptual vision problems.

The article presents a list of symptoms of learning-related vision problems and states that your child may have a learning-related vision problem if you identify one or more of these symptoms.

  • Headaches or eye strain
  • Blurred vision or double vision
  • Crossed eyes or eyes that appear to move independently of each other (Read more about strabismus.)

Cortical Visual Impairment (CVI)

Cortical visual impairment (CVI) may be defined as bilaterally diminished visual acuity caused by damage to the occipital lobes and or to the geniculostriate visual pathway. CVI is almost invariably associated with an inefficient, disturbed visual sense because of the widespread brain disturbance. (taken from http://www.aph.org)
