Description
5365 Brock Technique Transparency Set
The Brock Technique is a classic vision therapy tool for the diagnosis and training of strabismus (“crossed eyes”) and amblyopia (“lazy eye”). At the heart of the Brock Technique are 28 8″ x 10″ acetate transparencies, among which dozens of overlay combinations are possible, and the positioning of specific target forms is widely variable.
- Though many target forms are designed to appeal to children, the transparencies are effective for use with all ages
- Six targets have scales that can be read directly in diopters at the 16″ distance
- Requires a 2121 Light Box and a 6103 Brock Technique of Strabismus Theory

A carrot with red and green parts provides a check on suppressions. |

Panda and bear move in opposite directions. Useful in developing speed and accuracy of perception. |
 |
Used for suppression training in conjunction with almost any slide combination desired. |
 |
Rings may be moved in same or opposite directions to develop gross or refined stereopsis. |
 |
Very effective means of eliciting stereopsis in the exam. Aids in developing quick stereo judgment. |
 |
Often used with “circle” slides shown above as a reference point for stereo judgments. |
 |
Space ship and ring move in opposite directions. Combines central and peripheral training. |
 |
Especially useful with a form of cheiroscopic tracing in the rehabilitation of amblyopes. |
 |
Has a pronounced three-dimensional effect. Widely used for hand-eye coordination training. |
 |
Used with picture slides for para-macular fusion and plane of reference in stereo training. |
 |
Photoscene (in both green and red) has pronounced 3-D qualities, offers many training possibilities. |
 |
A binocular fixation target used with other slides to help develop precise spatial judgments. |
 |
This transparent sheet is used as a performance check on stereopsis and to detect malingering. |
