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. -

Lightweight 37mm square plastic prisms are ideal for testing and dispensing to patients. Available in 4 standard sets. Item #: AS+ -
Both Near and Far come with a single 6 PD stick prism. These cards allow direct measurement of the distance and near phorias in real space or with a phorpter. The patient simple has to tell which number the arrow points to. Any odd number (in yellow) shows esophoria while the even numbers (in blue) shows exophoria. An AC/A can quickly be determined with trial lenses. The reverse side of the near card has a X-Cyl target, and a variety of letter and word targets. Near card is about 12" wide. Distance chart is about 24" wide. Item #: CDHP+ -
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.
