This page documents hard-to-find assessments and literature related to visual-impairment research. In particular, there are tests that were created for assessing the cognitive abilities of individuals who have visual impairments, which are no longer in production and are difficult to acquire. Therefore, I am documenting them here for reference purposes. The materials from each test may or may not be complete, but include everything in the original copies I have/had in my possession.
