Abstract
Darbs ir uzrakstīts latviešu valodā uz 53 lapaspusēm. Tas satur 41 attēlu, 2 tabulas, 15 pielikumus, 59 atsauces uz literatūras avotiem. Darba mērķis: izvērtēt asaru plēvītes stabilitāti un mirkšķināšanas kvalitāti un kvantitāti datora lietotājiem. Metode: Tika aptaujāti Latvijas Universitātes Dabaszinātņu akadēmiskā centra darbinieki, no kuriem tika atlasīta grupa mirkšķināšanas un asaru plēvītes stabilitātes novērtēšanai. Rezultāti: Vidējais dalībnieku TBUT pirms lasīšanas 7,5 s, bet pēc 5,7 s. NIBUT pirms lasīšanas 10,2 s, bet pēc 7,4 s. Mirkšķināšanu skaits lasīšanas laikā 7 reizes/min. Pirms lasīšanas mirkšķināšanu skaits ir 20 reizes/min. Lasīšanas laikā šis skaits samazinās. Secinājumi: Lasīšanas laikā samazinājās mirkšķināšanu skaits, kā arī plēvītes stabilitāte.
Master thesis is written in latvian. It contains 53 pages, 41 figures, 2 tables, 15 attachments and 59 references. Purpose: To evaluate tear film stability and blinking quality and quantity for computer users. Methods: Participants had to fill out questionnaire. Some of them were chosen to evaluate blinking and eye structure. Results: Average TBUT before reading was 7.5 s but after reading 5.7 s, and average NIBUT before reading was 10,2 s but after reading 7,4 s. Average blinking while participants were reading was 7 times/min but before reading it was 20 times/min. When people are working with computer their average number of blinks decrease. Conclusion: During the reading task number of blinks and tear film stability decrease.
