For people who are colorblind, life involves little workarounds and big compromises alike. Daily challenges range from not knowing whether meat is fully cooked to not being able to read whether a horizontal traffic light is showing green or red. More serious repercussions include being shut out of a dream job, like piloting planes, because misreading landing-strip lights can have life-or-death consequences.
Now, a host of new research and tools promise to improve life for the estimated 32 million Americans–8% of men and 0.5% of women–who have some degree of colorblindness. For many, getting through the day–avoiding wardrobe perils and worse–has often involved bringing in a second pair of eyes. But new websites and smartphone apps offer to help identify or enhance hard-to-see colors. Videogame manufacturers are increasingly including “colorblind” modes in their games. And researchers are homing in on more specific vision tests that may allow mildly colorblind people to qualify for jobs that, until now, have been closed to them.
