Linear picture 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.
