Color vision test

Each plate is a circle of dots. If you see a number in it, tap that digit, then tap Next. If you do not see a number, tap No number. That is a useful answer too.

• Turn the screen brightness up, and turn off night mode and color filters.
• Use steady room light with the screen about an arm's length away.
• The first plate is a demonstration that every kind of color vision can read. How many plates follow depends on your answers.
• On a keyboard, type the digit and press Enter for Next. Backspace deletes.

An original screening, not the Ishihara test and not a diagnosis. Your answers stay on this device.

A screen estimate is not an eye exam.
