Description

Our Kay Picture Test Screening Chart is a double sided distance screening chart for vision testing at school entry, GP practice or other screening environment without the child needing to know capital letters. This is a very quick and easy test process with single and line presentation at three metre test distance.

The Kay Picture Test Screening Chart uses our new, fully researched picture optotypes which provide reliable visual acuity measurement comparable with ETDRS.

It measures from 0.80 to -0.10 (3/19 – 3/2.4) with the last five sizes having a linear format so that a crowded acuity measurement is possible. The central row of four pictures can be scored to provide an acuity measurement per optotypes. The chart is suitable for children aged 4+.

Full instructions are included.

Distance

We recommend that the screening chart is used at 3 Metre (10 feet) distance to achieve good concentration and cooperation from young children. There should be no significant difference in acuities at these distances for most children.

If testing at 6 metres with our three metre chart, the notation must be changed as follows:

Snellen fraction:
Change the numerator figure from 3 to 6, so 3/6 size picture at three metres becomes 6/6 at 6 metres.

LogMAR:
Take 0.3 from the score shown on the chart, so 0.3 Size at three metres becomes 0.0 size if tested at 6 metres.
