Achromatopsia - a genetic visual disorder that effects about 1 out of every 33,000 Americans - leads to severe vision problems, generally beginning at a young age. People with this disorder are extremely sensitive to light, have trouble seeing during the day (when it is bright out) and cannot see any color.
