Description
The Optec 1000-21 Secondary Test Slide evaluates far-point visual acuity and muscle balance in secondary school-age children and adults. It combines binocular or monocular acuity testing with separate lateral and vertical phoria assessments.
The acuity section allows the examiner to test the right eye, left eye, or both eyes simultaneously across a range from 20/200 to 20/20. The lateral-phoria test uses 1-diopter increments, while the vertical-phoria test uses ½-diopter increments for more detailed eye-alignment screening.
This optional slide is suitable for school health programs, occupational examinations, routine clinical screenings, and general adult vision assessments using the Optec 1000P Vision Screener.
