Abstract: A method and apparatus for administering eye tests to identify cone sensitivity loss associated with hereditary and acquired color vision loss which may be used for early detection, progress, treatment, and monitoring of eye conditions, traumatic brain injury, optic neuritis, systemic and neurological diseases including Glaucoma, Retinopathy, Age-Related Macular Degeneration, Multiple Sclerosis, Alzheimer's Disease, and Parkinson's Disease and retinal toxicity. Particularly, the method and apparatus disclosed uses a Cone Contrast Test (CCT) to test individuals for hereditary or acquired color vision loss associated with (a) early signs of potential disease/damage/toxicity in an effort to (i) provide opportunity for treatment, and (ii) prevent permanent eye damage, and (b) monitor progress and treatment of such disease/damage/toxicity.

Abstract: A set of gaming blocks, including a plurality of hexomino game blocks, is provided. The game blocks can be used as part of a game, puzzle, model or toy. The game pieces are particularly configured to include a predefined tolerance to assist with arranging and/or stacking of the game pieces. A playing board assembly is provided that has a curved, surface engaging face to provide for more challenging game play.
