Abstract [sv]

Syfte: Syftet med den här studien var att jämföra Digital Eye Strain-symptom mellan läsning på papper och mobiltelefon. Att undersöka om det som tidigare studier har visat i skillnad mellan läsning på papper och en datorskärm även gäller mobiltelefoner och hur mycket våra ögon påverkas när det gäller ansträngning, trötthet och andra ögonrelaterade symptom. 

Metod: Deltagarna (n=16) fick läsa i 20 minuter tyst, antingen på papper eller en smartphone-skärm. Avståndet fick de själva bestämma. De läste samma bok med samma typsnitt och storlek på båda medierna. Direkt efter de hade läst i 20 minuter fick de fylla i ett frågeformulär som bestod av tio frågor kring deras upplevda ögonsymptom under uppgiften.

Resultat: Studien visade på signifikanta skillnader i medelvärdet mellan papper och mobiltelefon på tre av symptomen: suddig syn vid tittande på texten (p=0,016), ansträngda ögon (p=0,023) samt trötta ögon (p=0,015). I alla tre fallen var symptompoängen högre efter läsning på mobilskärm än efter läsning på papper. Det fanns ingen signifikant skillnad mellan de övriga sju symptomen. Det var även en signifikant skillnad i läsavstånd med ett betydligt mindre avstånd till mobiltelefonen än till pappret.

Slutsats: Studien visar att symptomen efter användning av mobiltelefon upplevs som svårare än efter läsning på papper. De tre symptom som skilde sig signifikant var alla högre efter läsning på mobilskärmen.

Abstract [en]

Purpose: The purpose of this study was to compare Digital Eye Strain DES-symptoms after reading on a printed hardcopy versus a smartphone. To understand if results obtained from earlier studies that have showed DES when reading in from computer also applies to smartphones.

Methods: 16 participants in the study were asked to read a Swedish book quietly for 20 minutes, either on a hardcopy or on a smartphone. The participants were told to use their normal working distance while reading from book or smartphone. They read the same book with the same textsize and font in both conditions. Directly after reading the participants completed a written questionnaire that consisted of ten questions about their level of ocular discomfort during the task.  

Results: This study showed significant differences in mean symptom scores between printed hardcopy and smartphone on three of the symptoms; blurred vision while viewing the text (p=0,016), eyestrain (0,023) and tired eyes (0,015). In all three cases the symptoms were higher during smartphone use. No significant differences were found between the other seven symptoms. There were a significant difference in reading distance, smartphone were held closer than the hardcopy.

Conclusion: This study shows that the symptoms after smartphone use is perceived as more severe than after reading on a hardcopy. The three symptoms that showed a significant difference were all higher after smartphone use.
