A E K A E K A E K HOWTO APPLY PRESS-ON PRISMS • There is no need to determine the optical centre of the lens. • The glossy side of the Press-On is applied to the inside of the ens. 1. Place the lens onto the Press-On with the inner side of the lens facing the smooth surface of the prism, according to the prescription. 2. Trace the shape of the lens onto the Press-On. 3. Cut the Press-On (1 mm less than the traced shape). 4. Moisten the inside of the lens and apply the Press-On prism with the glossy side facing the inside surface of the lens. Do not use any adhesives. CORRECT POSITIONING OF PRESS-ON PRISM ON LENS The base orientation of the prism is indicated with the word “base” on the prism edge. Mark lens and prism at the same position on their edges to indicate alignment. The Press-On must be positioned onto the lens according to the BASE description indicated in the prescription: NASAL, TEMPORAL, TOP, BOTTOM, DIAGONAL. 4 ALL RIGHTS RESERVED © Prism 7.1 PRESSON EEC dir.93/42 PRISM POWERS IN DIOPTRES - Prism 67 mm - 1 pc.

Binocularity degrees 28 7.3 ALL RIGHTS RESERVED © DIAGNOSTICS 1° degree - Simultaneous perception or Biocularity The development of Binocularity occurs gradually, and it is possible to divide it into different steps. Worth distinguished three phases and named them "degrees of development of binocular vision": 1° degree - Simultaneous perception or Biocularity: the simultaneous perception of the two eyes without the possibility of binocular fusion. Through this phase it is possible to investigate the presence or absence of suspension or suppression and to detect heterophoria. Test example: Test with prism Von Graefe. 2° degree - Flat fusion or Binocularity: two images strike the two retinas in corresponding points, after having reached the occipital visual cortex, and are associated in a single image that represents the fusion of the two primitive images. Test examples: Worth's lights or Red Filter Test. 3° degree - Stereopsis: a visual-perceptive process which, starting from two slightly different monocular retinal images, leads to the sensation of depth. It occurs only at the level of the striated cortex where the re-elaboration of the information of the two eyes occurs. Examples of stereotests; Lang, Titmus, Butterfly. Ref. 08307 Prism of 6 prismatic diopters (∆) useful to detect the first degree of biocularity. The prism must be paced with a vertical base in front of one of the eyes while the person is fixing a point-like target projected from a distance. A prism of this power cannot be compensated for by vertical fusion reserves, therefore, under normal conditions, the person should report vertical diplopia. Otherwise it could be a case of suppression. Before proceeding with further investigations, move the prism to the other eye or flip the base PRISM 6 ∆ 1 pc.

NEW 2° degree - Flat fusion or Binocularity 29 7.3 ALL RIGHTS RESERVED © DIAGNOSTICS Ref. 08311 Red occluder 1 pc. Ref. 08349 Black translucent occluder 1 pc. Ref. 08317 White light pen 135 mm - 1 pc. 2 batteries AAA 1,5V included. Ref. 08306 Flashlight with 4 coloured dots (one red, two green and one white) with a diameter of 6mm each and anaglyph glasses with red-green filters. Test performed to assess the presence of flat binocular fusion and its stability in different gaze positions from near and to detect the presence or absence of monolateral and/or alternating suspension or suppression. The test can be performed while wearing prescription lenses or with trial lenses, in low lighting conditions. Worth's test should also be performed in cases of reduced visual acuity that does not improve with the pinhole test. 3 Batteries AA 1,5V not included. WORTH 4 DOT FLASHLIGHT WITH RED-GREEN GLASSES The red occluder determines a level of dissociation between the two eyes. The purpose of the test is to evaluate the fusional stability (hence the quality) of binocular vision at different distances and in different gaze positions. The red filter test can highlight the presence or absence of suspension or suppression of the monolateral and alternating type. It is recommended to use the pen-light and the black occluder to carry out the test. RED FILTER + PENLIGHT + OCCLUDER
