Prevalence of Digital Eye Strain  

The use of digital screens has increased significantly in recent years and, in particular, during the past 9 months since the beginning of the current pandemicMany people may be concerned about the effect of this extended exposure for the eyes and the visual system but, so far, little is known. 


Digital Eye Strain or Computer Vision Syndrome is defined by the American Optometric Association as a group of eye and vision related problems associated to long-term use of computer, tablet or smartphone. With this survey we want to investigate how digital eye strain is affecting people living in Sweden. We hope that in the future we will be able to better understand the condition, in order to provide advice and treatments to prevent digital eye strain.
