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. -
The Direct Digital Pupil Gauge is a simple and inexpensive way to measure both monocular and binocular distances between eyes. This is necessary for accurate fitting of various ophthalmic lenses, especially multi-focals. It works by simply aligning the vertical stripes over the center of each pupillary reflex. -
The Digital Pupilometer is a digital precision optical instrument designed for accuracy but with ease of use in mind as well. The device uses corneal reflection alignment system with high accuracy digital linear sensors. The large LCD screen provides easy reading for the technician. The measuring range is 46mm to 82mm binocular and 23mm to 41mm monocular. Includes automatic standby after 2 minutes of non-use to preserve battery life. This lightweight unit is powered by 4 AA batteries (not included). -
Upgrade your vision therapy to a whole new level with the Stereo Vision Chart Series. Patients love stereo targets, but often we cannot send them home...until now! With the Stereo Vision Chart Series, you have access to economical and efficient training tools to integrate binocular vision training while training other visual skills simultaneously. The Stereo Vision Charts provide an excellent fusion lock and a wonderful depth of field. The depth is subtle and great for working with just noticeable differences (JNDs). They are great for working with pilots, athletes and others who want to refine their depth perception awareness. -
