VectorVision Contrast Sensitivity Testing Unit (Includes Testing Box and Test Chart) The VV1000 is used clinically by eye doctors in over 45 countries to evaluate cataracts, glaucoma, diabetic eye disease, contact lens performance, refractive surgery, etc. In addition, the instrument has been selected for use in numerous multi-center trials for the evaluation of contrast sensitivity, ETDRS acuity, low contrast acuity and glare sensitivity. These studies include those for PRK refractive surgery, contact lens evaluation, LASIK refractive surgery, athlete visual performance, visual impact of pharmaceutical treatments, etc. The patented CSV-1000 standardization insures that testing light levels do not vary due to changes in line voltage or due to bulb aging. No other vision testing instrument offers this standardization package. The VV1000 is the only self-standardized vision testing instrument. In each row of the device, photocell circuitry continually monitors and calibrates the instrument light level. This unique system senses both the external light striking the face of the instrument and the internal light which emanates from the miniature fluorescent bulbs. By measuring both light sources, the patented circuitry (U.S. Patent Number 5,078,486) determines the total light reflected from the instrument face and provides for a constant test luminance level of 85 cd/m2. The CSV-1000 is operated by wireless remote control so that each row of the instrument can be individually lighted for easier viewing by the patient. The VV1000 can be used with a variety of tests. The VV-1000 can easily rest on a table, hang on the wall or be used with rolling floor stand. The instrument can be easily transported from office to office or to out-of-office screening locations. -
Vectographic Projector Slide Adult Slide This adult projector slide test depth perception and binocularity under distance conditions. The top portion of each slide is a standard non-vectographic projector slide. The bottom portion is a vectographic slide that contains suppression control targets, a distance stereo acuity test, fixation disparity and binocular balance. These slides fit most standard A-O and Marco projectors, and are adaptable to a 10' or 20' lane. REQUIRES POLARIZING SCREEN. -
4" x 5-1/2" Polarized vectograms ensure testing and training at actual distances. Vectograms stabalize fusion and steropsis, eliminate suppression and develop simultaous 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 Polachrome™ Trainer -
8-1/4" x 5-1/2" Polarized vectograms ensure testing and training at actual distances. Vectograms stabilize fusion and steropsis, eliminate supression and develop simultaneous vision.

The 801 Slide Set combines both vertical and horizontal targets. Variable fusional training is achieved for either vertical or lateral imbalances by simply rotating the targets and 550 holder 90 degrees. The Box-X-O anti-suppression check separates the vertical and lateral targets and alignment check, regardless of the orientation. The 802 Slide Set has two horizontal targets with differing stereoscopic demands, and monocular clues for those who might have difficulty achieving or maintaining 3-D images. -
Variable Tranaglyph™ Kit (500 Series) Variable prismatic red/green slides help build initial fusional reserves through peripheral and central fusion as well as stereopsis. Effective home training slides feature 5.5" x 10.5" red/green targets on transparent vinyl. Item #: BC500+
