What is the Sonksen logMAR Test (SLT)?
logMAR The SLT is a new visual acuity test which has been carefully researched with 3000 two to nine year olds. It was developed by a team of experts from the Institute of Child Health, University College London.
A unique feature of the test is that it is published with centile charts of acuity (similar to those used for growth) from 2 years 9 months to 7 years 9 months - a period of very rapid changes in acuity
