The present invention is to introduce a computer-implemented, web-based stereoscopic acuity computation and stereo eye color accuracy assessment to test for what colors patients are deficient in as seen through the real world in pictures rather than just for color by itself. The pictures are taken with a camera or similar electronic device use. The eye color accuracy exam utilizes caffeine products. The computation takes color characteristics of a target color where they are inputted, identified matched, and processed in a way as to expose a visual deficiency of the target color selected from a color database and color chart based upon color characteristics of the target color to be matched, processed, and visually stereoscopically displayed thus enabling comparison of the alternate color(s) with the target color. The computation uses gamma correction, color thresholding, alpha composing, opacity ratios and eye color accuracy assessment from a patient to provide a result.
