Certified Ophthalmic Assistant Practice Exam

Acuity testing of an illiterate person and preschool children can be performed with all of the following tests EXCEPT

1. Allen cards

2. a potential acuity meter

3. An E Cube

4. Landolt's broken ring chart

The correct answer is: a potential acuity meter

Acuity testing of an illiterate person and preschool children typically requires special testing methods that do not rely on reading letters or numbers. Allen cards, An E Cube, and Landolt's broken ring chart are all examples of tests specifically designed for individuals who are unable to read. These tests utilize pictures, shapes, or other symbols that can be used to assess visual acuity without requiring the ability to read. On the other hand, a potential acuity meter (choice B) is not typically used for individuals who are illiterate or preschool children, as it relies on the ability to discern letters or numbers.
