Cones and Rods

Cones and Rods is an application that tests, simulates and corrects colour vision.

This application can not only determine whether you currently suffer from colour blindness, it can also determine what type of colour blindness you suffer from.

You can see the world from the eyes of the colour blind using the simulator, you can simulate colour blindness on any deficiency type using either any photo in your photo library or the iPhones camera. The following colour blindness deficiencies are supported:
- Protanopia/Protanomaly (Red Deficient)
- Deuteranopia/Deuteranomaly (Green Deficient)
- Tritanopia/Tritanomaly (Blue Deficient)
- Achromatopsia/Achromatomaly (Monochromacy)

The correction function allows colour blind people to accurately identify colours by converting hues to there more basic levels. This allows colour blind people to accurately identify numbers in Ishihara tests and other real world situations. The following colour blindness deficiencies are supported:
- Protanomaly (Red Deficient)
- Deuteranomaly (Green Deficient)
- Tritanomaly (Blue Deficient)

Note to iPod Touch users: You will not be able to access the Camera views, and will only be able to simulate/correct colour vision using your Photo Library.
