Star Tracing - 8 Point Star

Developed exclusively for Opto. Available now for iPad!


Star Tracing is designed to improve fusion of images with similar borders. Parts of each picture are only visible to one eye to check for suppression.

Patients use two styluses, one in each hand, to trace the star shape from point to point in the order indicated on the screen. Includes 4 variations.

Tip: Do this exercise standing up! This exercise makes excellent use of the Stereoscope for iPad in a vertically mounted position. The Stereoscope for iPad stand features a strong magnetic base that can be attached to any flat magnet-friendly surface such as a magnetic white board or filing cabinet.

Required hardware: Stereoscope for iPad
