The APH Museum is closed, and our Factory Tours have stopped as we begin construction for our museum expansion. You can continue to explore our collection online at APHmuseum.org.
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
