The new Random Dot 3D Clock Variable Tranaglyph is an excellent new training device for both the mid-level and final stages of base-in and base-out therapy. Unlike the typical 3D training images, random dot images can not be seen unless the highest level of fusion is achieved. The images simply look like a page full of dots, until the two eyes and brain combine these two sets of unique images into a single three dimensional image. This makes it an excellent therapy technique for those patients who are simply guessing or malingering with traditional cards sets. The level of fusion needed is the most difficult to obtain and requires the highest level of visual processing, which makes it an excellent finalization exercise. For patients who have had limited binocular vision, such as the recently corrected amblyopic or strabismic patient, this task may prove to be too difficult. For those patients, you may need to start with a 500 series tranaglyph, then progress to the 600 series and finalize with the Random dot series. Item #: BC12+ -

Six-piece set includes: 2D,3D,4D,5D,6D and 8D flippers. Professional training with two prism pairs. Beginning with the highest powers through which a patient can fuse and focus, prism flippers are exchanged for next higher powers through the training sequence. GREAT FOR BEGINNING PRESBYOPES WHO HAVE EXO WITH THEIR BIFOCALS! All flippers have corrected curve lenses and come in a deluxe black carrying case. Save money with this kit! Note: Prism diopter powers are listed per lens. For example, a 4PD flipper will have two 4PD lenses to make a 8PD range. So, 4PD flipper = 8PD range. Item #: BC1275SETCC -
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. -
Designed by two low vision doctors. This chart has a 20/630 size number as well as numbers & tumbling "E's" that are 20/500, 20/400, & 20/317 sizes. These take the memory out of acuity testing. The 20/250 page & below have four numbers of the same size. This allows you to test each eye individually without concern for memoriztion. Also, by observing which number is seen first, the tester can decide which part of the field has the best fixation. Chart lists size by logmar & Snellen equivalent to 20/20. -

8-1/4" x 5-1/2" Polarized vectograms ensure testing and training at actual distances. vectograms stabalize fusion and steropsis, eliminate suppression and develop simultaneous vision. Used in monocular, binocular, pursuit and saccadic training, vectograms help correct and prevent anomalies involving projection and hand-eye coordination. Ideal for use with Bernell's Dual Polachrome™ Trainer. -
This test can be used with infants, children and adults with low cognitive abilities when communication difficulties prohibit the use of optotype tests to measure visual acuity. This test measures an individual's ability to detect the presence of parallel lines of decreasing width to provide information about the function of some parts of visual pathways. Item #: GF1300 -
The BASS-PL series is a highly sensitive measure of the relationship between Binocular alignment (fixation disparity) and Accommodative function (clarity) during a Series (stamina) of cognitively loaded Saccadic eye movement.
