Original Kay Letter Test (8 Letters)
The original Kay Letter Test is a linear letter acuity test comprising eight Sloan letters that are recommended British and US Standard test letters.
It contains comprehensive LogMAR sizing at three metres from sizes 1.00 to -0.10, plus near testing with LogMAR letters and high frequency words. Additionally, Snellen equivalent sizes in metres and feet are also given.
This system uses a Crowded LogMAR test and fully complies with the recommendations for School-Entry vision screening prescribed by the UK National Screening Committee and Public Health England. Full instructions are printed on the inside cover.
The Kay Letter Test book measures 26cm x 17.5cm and all its pages can be wiped clean in compliance with infection control guidelines. In addition, the test book covers are encapsulated with robust plastic and the internal pages are matt laminated.
The test is packaged in a frosted PVC wallet with flap closure for safe storage in between uses.
|Dimensions||26 × 17.5 cm|
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.
