Sleep quality and quantity impact domains of daytime functioning, attainment, and global development. Previous work has explored sleep profiles in typically developing children and children with developmental disorders such as Down syndrome and Williams Syndrome, yet there is a complete absence of published work regarding the sleep profiles of children with vision impairment aged 4\u201311 years. This is the first known study that examines the sleep profiles in children with vision impairment (n = 58) in comparison to 58 typically developing children (aged 4\u201311 years) in the UK. Sleep was measured using the Childhood Sleep Habits Questionnaire (CSHQ; parental report), actigraphy and sleep diaries. Results showed group differences in subjective CSHQ scores but not objective actigraphy measures. Surprisingly, the findings revealed disordered sleep (namely, poor sleep quantity) in both groups. Discordance between CSHQ and actigraphy measures could represent heightened awareness of sleeping problems in parents\/caregivers of children with vision impairment. The implications of this study extend beyond group comparison, examining disordered sleep in \u2018typically developing\u2019 children, exploring the potential role of light perception and the importance of sleep quality and quantity in both groups.<\/jats:p>","DOI":"10.3390\/brainsci11040421","type":"journal-article","created":{"date-parts":[[2021,3,26]],"date-time":"2021-03-26T13:17:53Z","timestamp":1616764673000},"page":"421","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Lights Out: Examining Sleep in Children with Vision Impairment"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8123-0681","authenticated-orcid":false,"given":"Jessica","family":"Hayton","sequence":"first","affiliation":[{"name":"Department of Psychology and Human Development, UCL-Institute of Education, London WC1H 0AA, UK"},{"name":"Sleep Education and Research Laboratory, UCL-Institute of Education, London WC1H 0AA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica","family":"Marshall","sequence":"additional","affiliation":[{"name":"Department of Psychology and Human Development, UCL-Institute of Education, London WC1H 0AA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6856-0595","authenticated-orcid":false,"given":"Dagmara","family":"Dimitriou","sequence":"additional","affiliation":[{"name":"Department of Psychology and Human Development, UCL-Institute of Education, London WC1H 0AA, UK"},{"name":"Sleep Education and Research Laboratory, UCL-Institute of Education, London WC1H 0AA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"13889","DOI":"10.1523\/JNEUROSCI.2592-15.2015","article-title":"Disrupted sleep: From molecules to cognition","volume":"35","author":"Cirelli","year":"2015","journal-title":"J.
