The Color Blindness Booklet for Toddlers was created for parents, teachers and guardians to test their children to check if they showed any signs of color blindness. The booklet was designed to be used with an adult and a child within the age range from 3 to 6. The adult reads the story to the child while the child traces the path through a differently colored line path in a large circle filled with select and specific colors that are commonly seen in color blind deficiency problems. Each page contains a hint to bring one animal across the differently colored line. The book is filled with fun and entertaining graphics to keep the child interested and amused. After the adult and the child finish up the book the adult then counts the amount of pages the child cannot complete and refers to the amount of pages that is problematic (Which is located in the very back.) The book is an eight inch by eight inch saddle stitch printed on 100# cover for the title page and 80# text for the guts. This book was created to be used in a school and home setting. It is easy to reproduce and it would be affordable for schools to buy large quantities. This book was actually printed out and presented to the committee. This book was a successful project because there is nothing like this being currently used on the market. The Color Blindness Booklet for Toddlers could possibly help parents find color deficiencies in an early stage of the child's life which would prevent future problems and possibly even learning disabilities.

The goal of this work is to develop a portable and accurate colorblind test that has advantages over the HRR and Ishihara plate tests, including that it is easier and faster to perform, does not require the subject to identify alphanumeric characters or geometric shapes, provides unambiguous results to the provider without interpretation, and is at least 8 times faster. The advantage over prior anomaloscopes is that it can be made in a hand-held version, uses binary matching choices rather than having the subject match colors with a tuning knob, and uses optimal reference color choices determined from established knowledge of human color perception. To successfully achieve this, cone spectral sensitivity curves and all subsets of four LEDs from a set of eight spanning the visible spectrum, the 1x4 metamer solution for a reference color for normal vision, deuteranomaly, and protanomaly are calculated. From these solutions, the optimized set of 4 LEDS was determined by maximizing the average angle between the normal, deuteranomaly, and protanomaly metamer solution vectors in the XYZ color space. To perform the test, the subject is asked to determine the best match for color and brightness in side-by-side display panels illuminated with distinctly different reference metamer color pairs for normal, deuteranomaly, and protanomaly vision. This allows the operator to directly and unambiguously determine the subject’s color vision type. The average duration to perform the tests are 30, 253, and 281 seconds for the anomaloscope, Ishihara 38 plate test, and HRR 24 plate test, respectively. When determining whether the subject has normal vision or is colorblind, the anomaloscope and HRR test results agreed for all 102 subjects. Because this rendition of the anomaloscope was designed to only distinguish between normal, deuteranomalous, and protanomalous vision, the 7 subjects that the HRR determined to be tritanomalous were not included in the results presented hereafter. The HRR 24 plate test and the anomaloscope agreed in their diagnosis 91/95 = 96% of the time, the Ishihara 38 plate test and the anomaloscope agreed in their diagnosis 94/101 = 93% of the time, and the HRR and the Ishihara agreed in their diagnosis 89/95 = 94% of the time. The approach described here can be extended to other types of color blindness.
