Kay Picture Test linear crowded acuity test with distance LogMAR sizing at three metres from 0.70 to -0.20, plus near testing and matching card. The pictures are presented in a row of five boxes to provide consistent crowding. There are four different arrangements of the picture optotypes at each acuity size. Suitable for naming and matching. Age 30 months+.
New, fully-researched picture optotypes that provide a reliable visual acuity measurement comparable with ETDRS. Six pictures have an improved and modernised design with consideration of recent research evidence on spacing and crowding. The six pictures were shown to be the most recognisable to children under 30 months and with minimum variability in legibility across the optotypes.

“The Flemish guideline in School Health Care concerning the early detection of visual impairment in schoolchildren recommends the use of the Kay 3m Crowded Book for pupils up to the age of 5 years.
Our experience with the Kay 3m Crowded Book is very favourable and the feedback from professionals very positive…. Because of its attractive pattern the Kay Crowded Test makes it much easier to get the participation of young children, compared to other tests.
I would like to express my greatest appreciation for your work related to the early detection of visual impairment in young children This has helped us a lot to design a successful screening program in Flanders.”
