Visual Field Fast PRO is the advanced version of the Visual Field Fast app by the same developer. 
It is an app that is designed to use the iPad screen to detect vision problems quickly. This App uses a novel stimulus to allow people to identify their vision problems. It can now test the Central 10 and 24 degrees of vision. The color and size of the stimuli are customizable. There is also a new Color Contrast setting to test vision in the axis of red-green, blue-yellow color confusion.
