£82.50Kays Crowded Set

The Kay Picture Test Three Metre Crowded Book combines the accuracy of LogMAR acuity testing with the ease of naming pictures. It is suitable for use with children aged from about 36 months.

Any child who doesn't yet know his letters can read out the row of pictures rather than struggle to match from a row of unfamiliar letters. This means the test will be easier for the child and quicker to perform.

Results can be relied upon since the pictures used are those already in Kay Picture Test single acuity tests with proven accuracy and twenty years of clinical use worldwide.

Also, since this is a naming test, there should be no need to point out each picture to help the child to find his place in a row. The examiner simply refers to adjacent pictures by name: "What is the one next to the apple/in front of the boot?" This adheres to the principle of accurate crowded acuity testing.

Eight pictures are used in groups of four throughout the test (except sizes 1.0 and 0.9 where there are two per line). Each eye is tested with a different arrangement of pictures to avoid memory playing a part. At each acuity level the same four pictures are arranged in a different order to test the other eye, giving a perfect comparison of the two acuities.

The test book comprises sizes LogMAR 1.0 to -0.1 in twelve equal steps. The index shows Snellen sizes in feet and metres as well as LogMAR, so there is no need to convert. The improved book has a new robust spiral binding and a page by page table to read the exact LogMAR score for each picture seen.

Full instructions are printed in the test book with a table for reading exact LogMAR scores.

The accompanying key card is to be used as a prompt only for shy or unco-operative children as the test is not intended for matching (except with older children or disabled adults who may match succesfully).
