Free Space Produts

The random dot images will give a unique 3-D Image when properly fused. The card set consists of 12 images that range from 4 PD to 26 PD in 2 PD increments. Some images should stand out toward the viewer and some will go away when properly fused. Which images stand out and which go away, will depend on whether the subject is crossing their eyes in front of the targets (crossed or base-out fusion) or crossing the eyes behind the target (uncrossed or base-in fusion). The standard viewing distance is 40cm.

Two first degree fusion images are placed at the top of each random dot box. A square is on the left side and a X is on the right. As with most eccentric fusion techniques, the viewer must visually center the X within the square to have proper fusion. This is achieved by crossing or uncrossing the eyes. Once fused, slowly lower your view to the random dot boxes below and the images should appear. If you cannot achieve fusion when doing crossed or base-out therapy, it may be necessary to use an aid (such as a pointer or pencil) placed in front of the random dot images to stimulate the proper crossing of the eyes. For the uncrossed technique, imagine that your eyes are crossing at a point behind the booklet.

The answers (Hidden Images) of each random dot card is located on the backside of the card.

Ramdom Dot Pads

Features random dot free-space fusion targets for various prismatic demand. A sequence of 12 different figures are repeated in increasing prismatic demands of approximately 2, 4 and 5 prism diopters. May be used for both Base-In and Base-Out training. Ideal for in-home training.

Progressive Freespace Fusion Cards

Two white and two clear cards with eccentric fusion images that get progressively further
apart to increase demand for eso and exo training. each line has separation listed. Demand increases from 8-26mm.

Polyfusion Transparent (VTE)

New version of well-known lifesavers. Suitable for self-instructed fusional activities with suppression check. Polyhedron on polycarbonate transparent support, anti-scratch material.

Size 15 x 21cm

Recommended for Base Out 2nd level fusional training and Base In 1st level fusional training.

Polyfusion Translucent (VTE)

Recommended for Base Out 1st level fusional training and Base In 2nd level fusional training.

Training card has three red targets printed in exact opposition to three green targets. Convergence is jumped from one target to the other. Target fixated is single; other two double.
High-quality card is used as a septum by holding an end against the nose.

This new progressive free space fixation training set is composed of 7 fixation cards. The free space cards set works to train both convergence and divergence reserves across a variety of cards. The first three cards feature two Wiley Cat targets with simple, progressively more difficult eccentric rings, and red/green rivalry tasks. The next 4 cards are increase fusional demand by either varying the distance or by cutting and separating the card. The cards are available in opaque or clear sets, please specify when ordering.
