Product Description

APH’s CVI Complexity Sequences Kit includes cards that present sequences of images designed to refine the ability to identify a target in the presence of increasing amounts of background information. These cards may be used individually or as a sequence and should be presented against a black or plain, light-absorbing background.

The CVI Complexity Sequences Kit is an important tool for use by:

  • Parents of children with Cortical Visual Impairment (CVI)
  • Teachers of visually impaired students (TVIs)
  • Instructors of TVIs
