Barrel Convergence Cards™

The Barrel Convergence Cards™ is a specially designed training card featuring three red targets precisely aligned opposite three green targets. The card is designed as a training aid for improving your convergence abilities by jumping your gaze from one target to the other. When you fixate on a single target, the other two appear double. The cards are made of high-quality material and can be held by placing an end against the nose, making them function as a septum. Use these regularly to enhance your visual convergence abilities. Come as a package of 10 cards.
