Product Details:
The Free-Space Fusion Cards are designed to support targeted binocular vision training by promoting flexible fusional vergence and depth perception. When properly fused, patients experience clear three-dimensional cues to assist in developing convergence (base-out) and divergence (base-in) skills.
This set includes both opaque and transparent cards. Opaque cards are recommended for convergence training, while transparent cards are typically used for divergence activities. As patients improve, either type can be adapted for use in both directions. Each card features clear alignment markers and depth references to assist in fusion accuracy. Suppression markers are also integrated to help monitor and manage suppression tendencies throughout the activity.
Training may be conducted with or without red/green filters. When used, the red lens (right eye) and green lens (left eye) enhance anti-suppression control. Cards are reversible, allowing for variations in perceived depth and facilitating both standard training and compliance testing.
Once the patient is comfortable with both convergence and divergence tasks independently, therapists can introduce alternating vergence activities (Base-In/Base-Out Rock) to further enhance dynamic flexibility and fusion resilience.
