Our Kay Pictures optotype visual acuity testing system is available in various near and distance book formats, screening chart and as a digital app. The redesigned paediatric vision test system provides an accurate, reliable, crowded acuity test to suit ages ranging from eighteen months to older children and adults with learning disabilities.

It comprises six pictures proven most easily recognisable to children between 18 and 30 months. The pictures have very similar legibility and are comparable with Llandolt C and ETDRS. The Kay Picture Test has been validated in a thorough research project by Liverpool University Directorate of Orthoptics and Vision Science.
