Brock's research in stereopsis

While Frederick Brock's contributions to vision training are numerous, little of his work dealt specifically with stereopsis, mostly concentrating on its application to diagnosis and therapy of binocular dysfunction. He did demonstrate, qualitatively, how differences in the size or clarity of retinal images affect stereopsis. The theoretical basis of his work, as well as his published and unpublished contributions, are reviewed in the context of the author's personal experience with this singular person.
