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.)

- Difficulty remembering what was read
- Omitting or repeating words, or confusing similar words
- Persistent reversal of words or letters (after second grade)
- Difficulty remembering, identifying or reproducing shapes
- Poor eye-hand coordination
- Evidence of developmental immaturity
Functional Vision Evaluation
The Texas School for the Blind website has resources for Functional Vision Evaluations. Use for resources to support individuals who are blind or have severe low-vision.
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)
