The Kay Picture visual acuity test is the Gold Standard vision test for pre-literate children. It provides accurate crowded visual acuity measurements earlier than symbol and letter tests in a fun and easy way.

The six pictures have equal legibility and are easily recognisable to children from 18 months of age. In the validation research project by Liverpool University Directorate of Orthoptics and Vision Science the crowded pictures showed high testability, sensitivity and specificity, so they provide an accurate, reliable and repeatable vision test.

We offer several near and distance book formats, screening chart and a digital app to suit different users, from orthoptists, optometrists and ophthalmologists to teachers and school nurses.
