Enchroma color blind test - EnChroma® Color Blind Test

This color vision test, known as the Ishihara Test, makes numbers out of dots that are a different color than the dots surrounding them.

Unlike a full-color spectrum, patients suffering from one of these color deficiencies see the world in yellow and brown tones.

Still, EnChroma makes glasses specifically for indoor use, and chances are that people wearing the indoor version of the EnChroma glasses are going to be staring at their devices a lot, just like everyone else does.
