“…Several tests exist for home monitoring of visual acuity in children. [56][57][58] In this study, we have chosen to look at tests that measure contrast sensitivity, as we were interested in two specific populations: children receiving treatment for amblyopia and those with other vision impairments. In amblyopes, it is known that the CSF is reduced even after treatment has restored visual acuity to normal levels.…”

PurposeTo investigate the feasibility of children measuring their own contrast sensitivity using a range of tablet‐ and paper‐based tests.MethodsForty children aged 5–15 years with amblyopia (N = 10), bilateral vision impairment (N = 10) or good vision (N = 20) measured their own vision on a screen‐based optotype test (Manifold), a gamified vision test (PopCSF) and a paper‐based test (Spotchecks) in a laboratory with minimal supervision. Completion rate, test–retest repeatability, test duration and participants' preferences were recorded for each test.ResultsMost participants (36/40) were able to perform all three tests. All tests were correlated with clinically measured visual acuity and contrast sensitivity (p < 0.001). The 95% coefficient of repeatability was 0.30 dB for Manifold, 0.29 dB for PopCSF and 0.13 dB for Spotchecks. All tests differentiated between children with reduced contrast sensitivity and control participants. PopCSF and Spotchecks were also able to differentiate between children with amblyopia and those with good vision. Median test time was 152, 130 and 202 s for Manifold, PopCSF and Spotchecks, respectively. Twenty‐two participants preferred the PopCSF test, 10 preferred Spotchecks and 6 preferred Manifold. Thirty‐nine out of the 40 children (98%) said they would measure their own vision at home using at least one of these tests every month.ConclusionsChildren and young people can test their own contrast sensitivity with repeatable results. Of these three tests, the most repeatable was Spotchecks, the quickest was PopCSF and participants' favourite was PopCSF. Nearly all of the participants said they would be willing to use at least one of the three tests at home.
