The Tangent Screen provides a very accurate method of charting the central and para-central field of vision. They are an invaluable aid in diagnosing pathological conditions. Testing is done at one meter. This screen is manufactured using the finest black felt available to ensure non-reflectivity. All markings are stitched in semi-visible black thread showing concentric circles, radial lines, and blind spots. These markings ensure ease of testing, scoring, and transcribing the mapped fields for visual field analysis. A white fixation button is attached. These roll-up screens include mounting hardware and a laminated scorecard. Available in 15° configuration which shows 24 Radians for maximum accuracy or 22.5° version which shows 16 radians. Tangent Screen measure 43" x 43" (1.1 m x 1.1 m).

The complete Sets include a roll-up screen with the choice of 15° or 22.5° radians, an 18" black wand, black scoring pins, a full set of test objects, and a laminated score sheet.
