Abstract
Maģistra darbs uzrakstīts latviešu valodā, datorsalikumā uz 53 lappusēm un satur 27 attēlus, 1 tabulu,1 pielikumu un tajā ir izmantots 41 literatūras avots.
Darba mērķis: noskaidrot kā akomodācijas atpalikšanu ietekmē ilgstošs tuvuma darbs pie LCD un LED datora monitora, izmantojot modificētās un klasiskās retinoskopijas metodes.
Metode: ar klasiskās dinamiskās retinoskopijas Nott metodi un modificētu dinamiskās retinoskopijas metodi tika novērtēta akomodācijas atpalikšana un tās izmaiņas eksperimenta dalībniekiem 2 stundu gara tuvuma darba laikā pie LCD un LED datora monitoriem.
Rezultāti un secinājumi: Rezultāti starp LCD un LED datoru monitoriem nav statistiski atšķirīgi, tomēr akomodācijas atpalikšana pie LED datora monitora pieaug lēnāk.
Atslēgas vārdi: akomodācija, dinamiskā retinoskopija.
Master thesis ir written in Latvian and it has 53 pages and it contains 27 pictures, 1 table, 1 appendix and there have been 41 literature sources used. The aim: to find out how to accommodation lag affecting the long-term proximity to work on LCD and LED computer monitor using a modified and classic retinoscope methods. Method: the classic dynamic retinoscope Nott method and a modified dynamic retinoscope method it was measured to accommodation lag and changes experiment participants in 2 hours beeing close to the LCD and LED computer monitors. Results and conclusions: The results between LCD and LED computer monitors are not statistically different, however, to accommodation lag with LED computer monitor is growing more slowly. Keywords: accomodation, dynamic retinoscopy.
