Summary Accommodation in children and non‐verbal adults can be difficult to assess using standard subjective techniques and hence is often not evaluated. By using a modification of Nott dynamic retinoscopy, rapid objective evaluation of accommodative function is possible. In this study, accommodative response to a range of accommodative demands was measured in 55 normally sighted children and young adults using dynamic retinoscopy. The data were found to fall into four age groupings: 3–10‐year‐olds' mean accommodation was accurate to within 0.5 D, although 3–5‐year‐olds over‐accommodated slightly, while 6–10‐year‐olds under‐accommodated. Subjects over 10 years of age showed under‐accommodation which increased with accommodative demand. These norms are presented for clinical use against which measurements on an individual paediatric or non‐verbal patient can be compared. Future studies will determine whether specific patient populations, e.g. patients with cerebral palsy or low vision, demonstrate normal or reduced accommodation.
