Effects of Lighting on Reading Speed as a Function of Letter Size. / William Seiple in American journal of occupational therapy, Vol. 72, n° 2 (March/April 2018)

Public ISBD [article]  inAmerican journal of occupational therapy > Vol. 72, n° 2 (March/April 2018) . - pp.1-7 Titre : Effects of Lighting on Reading Speed as a Function of Letter Size. Type de document : Article Auteurs : William Seiple, Auteur ; Olga Overbury, Auteur ; Bruce Rosenthal, Auteur Année de publication : 2018 Article en page(s) : pp.1-7 Langues : Anglais (eng) Descripteurs : HE Vinci Dégénérescence maculaire ; Lecture ; Photothérapie ; Vision Résumé : OBJECTIVE. We sought to determine under what conditions brighter lighting improves reading performance. METHOD. Thirteen participants with typical sight and 9 participants with age-related macular degeneration (AMD) read sentences ranging from 0.0 to 1.3 logMAR under luminance levels ranging from 3.5 to 696 cd/m2. RESULTS. At the dimmest luminance level (3.5 cd/m2), reading speeds were slowest at the smaller letter sizes and reached an asymptote for larger sizes. When luminance was increased to 30 cd/m2, reading speed increased only for the smaller letter sizes. Additional lighting did not increase reading speeds for any letter size. Similar size-related effects of luminance were observed in participants with AMD. CONCLUSION. In some instances, performance on acuity-limited tasks might be improved by brighter lighting. However, brighter lighting does not always improve reading; the magnitude of the effect depends on the text size and the relative changes in light level.
