Flippers are used to test and train for accomodative facility, accommadative rock, positive/negative relative accommodation and convergence and fusional convergence reserves. May delay bifocal use with some early presbyopes. Flippers assists in hyperopia screening and lens demonstrations. Help determine dominancy and powers when fitting monovision contacts. Durable white plastic holds shape under low heat for lens insertion. Powers listed on handle. Deluxe Black carrying case or the economy flipper holder included. Item #: BC1270SETSP

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.

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
