Vergence Facility Prism
Vergence Facility testing has been shown to be one of the most important methods of detecting patients with binocular vision disorders and symptoms. Diagnosis of non-strabismus binocular vision abnormalities can be improved through the use of vergence facility testing at near.
The test is performed at 40 cm as the patient views a vertical 20/30 target or similar. Twelve diopter base out (BO)and three diopter base in (BI) prism is alternately placed before one eye; the patient is asked to report when the target becomes single and clear. This prism change is repeated for one minute and the clinician records the number of cycles performed during testing. Presence of suppression is indicated by a perceived lateral movement of a single target moving left or right of center, or no observed eye movement.
For testing at near, the recommended failure criteria is 15 cycles per minute which is easily recalled (sum of BI and BO demands). Recent research has shown this criteria valid for pediatric, adult and presbyopic populations.
Vergence facility testing allows the clinician to quickly identify patients with binocular vision problems in a primary care examination. The procedure requires less than 2 minutes of chair time, inexpensive equipment and minimal patient cooperation.
Vergence facility has a sensitivity of 0.80 (correctly identifying binocular vision problems) and a specificity of 0.65 (correctly identifying normal binocular vision) and therefore maybe used as screening a test for binocular vision problems. Vergence facility testing is easy to learn and can be administered by a technician.
“Dottie” Red-Blue Convergence Cards
Utilizes physiologic diplopia: patient will become aware of crossed physiologic diplopia when dots are nearer than the fused one, and uncrossed when a nearer dot is fused.
Exercise has added difficulty because the fusion of 2 different colors creates retinal rivalry.

Worth Four Dot Test
The Worth Four Dot Test helps evaluate color perception by stimulating the red, green and blue cone receptors in the retina. The test set consists of a high-quality, chrome flashlight with a pair of universal spectacles together with complete instructions. The flashlights in the test sets require 2 D-cell batteries, which are not included.
Pediatric Fixation Sticks
Pediatric fixation sticks provide a series of detailed accomodation-stimulation targets for the young patient. The targets are calibrated for near. Included are (as examples) a clown face, a dog, a beach ball, etc. Each target is in brilliant color for patient ease.The set consists of three (3) extremely durable plastic sticks with both sides utilized for targets.
Single sticks can be used for performing various tests: unilateral (cover/uncover) test at near, alternating cover test at near, pursuit testing, near point of convergence (NPC), motilities (ductions and versions), vergence facility at near, fixation stability at near in diagnostic positions of gaze, amplitude of accomodation, and accomodative facility. Dual sticks with different optotypes exposed to the patient can be used for saccade testing.
Fixation Sticks 4-Pack
For detailed accommodation stimulating targets. For use alone or together. Precisely calibrated. For saccade testing. Very durable printing.
Horizontal Prism Bar
Sizes - .5-1-1.5-2-3-4-5-6-8-10. Our prism bars are made of extremely high quality plastic, which are optically clear with an index of refraction of 1.49 and a light transmission value of 92%. The manufacturing process greatly reduces optical strain, producing prisms that virtually eliminate clinical birefringent effects.
Vertical Prism Bar
Sizes - 1-2-3-4-5-6-8-10-12-14-16- 18-20-25-30. Our prism bars are made of extremely high quality plastic, which are optically clear with an index of refraction of 1.49 and a light transmission value of 92%. The manufacturing process greatly reduces optical strain, producing prisms that virtually eliminate clinical birefringent effects.
Face Fixation Sticks 3-Pack
Face Fixation Sticks provide a series of detailed accommodation-stimulation targets for the young patient. The set consists of three (3) extremely durable plastic sticks with fixation faces smiling on one side and frowning on the other side. Single sticks can be used for performing various tests: unilateral (cover/uncover) test at near, alternating cover test at near, pursuit testing, near point of convergence (NPC), motilities (ductions and versions), vergence facility at near, fixation stability at near in diagnostic positions of gaze, amplitude of accommodation, and accommodative facility. Dual sticks with different opt types exposed to the patient can be used for saccade testing.
