Linear Crowded Book with near test and matching card, suitable from 30+ months.
Kay Picture Test Linear Crowded Book
The Kay Picture Test Linear Crowded Book with distance LogMAR sizing at three metres from 0.70 to -0.20. It also includes a 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. The test is suitable for naming and matching from an age of 30 months and to allow for the extra concentration needed with the linear presentation.
The Kay Picture Test Linear Crowded Book is packaged in a frosted PVC wallet with flap closure for safe storage in between uses.
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 encapsulated front and back covers of the books are fully sealed, edge-to-edge. The covers can be cleaned with an anti-bacterial agent or perhaps even an alcohol-based cleaner. The only area where this plasticised covering is compromised is at the holes for the spiral binding, so extra care should be taken to not allow liquid to leak into the holes.
The inner pages are laminated and not sealed at the ends. Any liquid that penetrates underneath the laminate will eventually discolour the pages and potentially lead to the sheets de-laminating at the edges. Anti-bacterial wipes could be used very carefully, whilst paying close attention not to get the edges too damp.
“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.”
Dr. Cecile Guerin, Flemish Scientific Society for Youth Health Care
