All Frisby Stereo Test Present "real depth" objects viewed with natural vision: not testing glasses are required. Each plate has four random-patten 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 purpose of the Frisby Screening Stereo Test - Single Plate, is to demonstrate the presence of stereopsis. -
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. -
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 -
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 -
This 4 mirror glass lens is used for viewing all quadrants of the anterior chamber without lens repositioning. Mirrors are placed at angles of 62 degrees. No flange. No fluid required. Removable handle screws into place. Lens diameter: 20mm Rim Diameter: 25mm Lens Contact Point: 9mm Comes with padded case Item #: AMPDSG -
Collection of 66 test cards for use during examination of children. Hanks Pediatric Optotypes - Calibrated from 6/60 to 6/4. Designed for this purpose and tested in clinical trials to confirm recognition of the symbols by young children. Landolt C & Illiterate E Optotypes are also included - Calibrated from 6/60 to 6/4. Color Vision Screening - Pseudo-isochromatic plates with letters, numbers, circles and trails. Quality Production - Each card is matt laminated and encapsulated for long life protection. Actual size of each card is 108 x 112mm. Item #: AUPTC -
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+ -
Fly Acuity Test with Lea SYMBOLS® Test designed to rapidly test for amblyopia & strabismus using gross thru fine stereopsis. (4800 to 20 sec of arc) - Graded Circle Test from 800 sec now down to 20 sec - No monoculur clues - New improved booklets - Answer Key on back cover - Includeds polarized viewers -
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 -
This test is designed for vision screening at schools and assessment of vision of children with special needs beginning with age of 5 years.
