First introduced in 1917 — 100 years ago the Official Ishihara Color Blindness Test remains the most well-known color blindness test and is the most widely used color vision deficiency test used by most optometrists and ophthalmologists around the world. This Deluxe Edition by Luxvision contains a complete set of 38 plates. Each 4-inch square plate is tipped into a high-quality bound album that allows you to easily progress through the test to measure incrementally higher color sensitivity and specificity. The Ishihara color test was named after its designer, Dr. Shinobu Ishihara (25 Sep 1879 – 3 Jan 1963) who graduated on a military scholarship from the Imperial University of Tokyo in 1905. In 1908 he began postgraduate studies in ophthalmology, first in Tokyo and later in Germany. He received his Iguacu Hokusai from the Imperial University in Tokyo in May 1916 and became a chief physician general in the Imperial Army. One of his first military assignments was to design color blindness testing for new recruits. His first two sets of plates were hand painted watercolors that included "hidden" hiragana characters and were tested with a color-blind colleague. A third version, created in 1917, replaced the hirahanga with Arabic numerals. The Ishihara is now the most accepted method for testing color blindness and deficiencies by leading authorities worldwide.
