ABCD School Bus Retinoscopy Rack
One paddle with glass lenses, shaped like a school bus. This paddle has 10 plus lenses (1, 2, 3, 4, 5, 6, 7, 8, 9, 10), one frosted lens and one -5 lens.
Inspired by Dr. Robert Arnold at Alaska Blind Child Discovery (ABCD).
Goniometer (Trusetal)
The goniometer is used to measure the angle of any abnormal head-tilt or an abnormal position, different from the vertical or horizontal position.
“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.

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.

Face Fixation Sticks 3-Pack
Prices are available in CAD and USD. Use toggles at top of page to change.
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.
Fixation Sticks 4-Pack
Prices are available in CAD and USD. Use toggles at top of page to change.
For detailed accommodation stimulating targets. For use alone or together. Precisely calibrated. For saccade testing. Very durable printing.
Magnetic Farnsworth 100 Hue Kit
Prices are available in CAD and USD. Use toggles at top of page to change.
The discs in the magnetic version are encapsulated in a sealed clear plastic box. The patient selects the discs using a magnetic pen to move them into a scoring area. When complete, scoring is easily accomplished by reading the scores through the bottom of the box. Tip the box and shake the discs into the selection area for the next patient!
Color testing becomes a game so that adults and children as young as 4 years old are much more engaged!
