Ideal for use with children or patients with a small palpebral fissure. The instrument consists of a highly polished truncated silver surfaced pyramid with a plane anteroir viewing surface over four mirrors. An aluminum handle set at 35 degrees is bonded to one corner of the lens. The lens is used in the diamond position (45 degrees) resulting in fewer adjustments of lowering and elevating the slit beam with either hand. Item #: OCIOPDSG -

Aperture Rule™ Set (12 Stereoscope sized cards) These cares are more complex and require more detail demand. They build flexibility, resiliency, attention to detail and reduction of visual fatigue. These cards contain large quantities of details and build large ranges of fusion (leading to high amounts of prism diopters of 'Base Out' and 'Base In' fusion ranges) 12 Cards -
All Frisby Stereo Test Present "real depth" objects viewed with natural vision: no testing glasses are required. Each plate has four random-pattern squares with a circle of pattern elements lying in depth relative to its surround. The depth effect is due to the circle and its surround being printed on opposite sides of the plate. The Frisby Stereo Test has 3 plates allowing for testing stereo acuity disparity as fine as 15 seconds of arc. -

Farnsworth Test for Congenital and Acquired color defects. The Farnsworth D-15 contains a reference disc holding notation 10 B 5 4 and fifteen numbered discs which make up an incomplete color circle. The patient arranges the discs and then evaluation of the patients arrangement separates 'normal' color perception from moderate and strong defects in deutan, protan or tritan axis color discrimination. The disks are spread out on a table and arranged by the patient. The Farnsworth D-15 test is a subset of the well known Farnsworth 100 Hue Test. It is intended for classification instead of in-depth study of color vision defects. The D-15 and 100 hue tests are correlated. Growing Importance of Color deficiency Screening: In addition to congenital color deficiency screening there is growing evidence that adult acquired color deficiency, especially in yellow and blue perception, can indicate medical toxicity and other problems. Increasingly complex security and medical systems also require verification of all three types of color receptors. How the D-15 test works: The Farnsworth D15 is called 'dichotomous' because it is designed to separate subjects into one of two groups, 1) Strongly color deficient or 2) Mildly color deficient or color normal. This is accomplished by the arrangement of vivid (saturated) colored discs. A perfect score shows normal color perception. A non-perfect score is used to determine a medium or strong color deficiency.
