School vision testing slides for Titmus models
V4, and
V2 are included as a package (above) with your new vision screener instrument, or are available individually.
Slide 18070 (Test No. 1, SF-1) for binocularity in both eyes is used to determine whether both eyes are being used together.
Slide 18103 (Test No. 2, SAS-2) meaasures Acuity in right and left eyes with Conventional Tumbling "E" symbol. Patient states which way the "E" points in each square.
Slide 18093 (Test No. 3, SPS-3) measures Heterophorias. Muscle imbalance - vertical and lateral - is tested at predetermind pass/fail levels. This test is administered first at far, then at near.
Slide 18086 (Test No. 4, SPCD-1) is used to test color perception. Titmus Pseudo-Isochromatic Plates reliably detect gross color anomalies, but does not classify the type of deficiency.
Slide 18082 (Test No. 5, SA-BRL-4) measure visual acuity. Results are calibrated at 20/20, 20/30, 20/40, 20/50, 20/70, 20/100 and 20/200. Tests can be administerd binocularly or with either eye occluded.
Slide 18073 (Test No. 6, SLP-1) measures lateral phoria. Desirable phoria scores are associated with quick, accurate eye fixations and precise, effortless seeing.
Slide 18089 (Test No. 7, SVP-1) measures vertical balance between the two eyes. Good vertical alignment is an important factor in comfortable, efficient, two-eyed vision and is related to efficiency in most occupations.
Slide 18081 (Test No. 8, SA-BRL-2A) measures visual acuity. Visual acuity test results are calibrated at 20/20, 20/30, 20/40, 20/50, 20/70 and 20/100. Tests can be administerd binocularly or with either eye occluded.
