## What is 3D Rings?

View two dimensional objects in 3D with one eye.

Also emulates a rotator.

Useful for optometrists as part of a vision therapy program.

Fully supports AirPlay so you can display your rings on a secondary display (either wirelessly with Apple TV or with an HDMI adapter).

Includes the ability to change both the speed and direction of rotation, and supports MFBF training with a choice of red, green or blue charts. Binocular (red/green) charts also available.

Supports Siri Shortcuts, so you can create your own shortcuts on the home screen to start exactly the chart you want at exactly the speed and colour you want.
