Barrel Convergence Cards

The Barrel Convergence Cards™ are a training tool designed to be used in vision exercises to train convergence skills. These cards feature three red targets and three green targets aligned opposite each other. When looking from one target to the opposite target, it can help enhance convergence ability. How to use The Barrel Convergence Cards: Hold the card in front of your face so that the three barrels are in a horizontal line. Focus your sight on the farthest barrel until you see it alone and hold it for 10 seconds, and the middle and front barrels appear double. Now focus your sight on the middle barrel until it appears alone and hold it for 10 seconds, and the other two barrels appear double. Alternate your convergence between the barrels for 10 seconds, making sure that the barrel you are looking at is single and the other two barrels are double.
