In Their Eyes

Ever wondered how the world looks to someone who's color blind? In Their Eyes lets you see it for yourself.

Point your camera at anything and watch the colors shift in real time to match how a person with color vision deficiency actually perceives them. It's an instant, eye-opening way to understand how color blind people actually see the world.

Color blindness affects roughly 1 in 12 men and 1 in 200 women, over 300 million people worldwide. Most of us never get to experience what that's like. Now you can.

SEE THROUGH THEIR EYES, LIVE
• Real-time camera simulation, just point and look
• Switch instantly between the major types of color blindness
• Take pictures with the color blind filter switched on

FOUR TYPES OF COLOR VISION DEFICIENCY
• Protanopia: red-blindness
• Deuteranopia: green-blindness (the most common form)
• Tritanopia: blue-blindness
• Achromatopsia: total color blindness (grayscale)

WORKS ON YOUR PHOTOS TOO
Load any picture from your library and see it transformed — perfect for checking how you photos look to a color blind person.

CAPTURE AND COMPARE
Save a side-by-side of the normal and simulated view to your photo library, so you can share and review what you discovered.

BUILT ON REAL SCIENCE
The simulations use scientifically validated color transformation matrices (Machado, Oliveira & Fernandes, 2009), the same approach used in professional accessibility tools.

PERFECT FOR
• Anyone who wants to understand how a colorblind friend or family member sees the world
• Teachers and students exploring how vision works
• Designers checking that their work is accessible to everyone

YOUR PRIVACY COMES FIRST
Everything happens on your device. No account, no tracking, no data collection — your camera feed and photos never leave your phone.
