About Digital Eye Strain e factors that contribute to digital eye strain fall into two main categories: the individual's visual ability (i.e., uncorrected refractive error, binocular vision disor- ders, accommodative disorders, and ocular surface or tear film abnormalities) and environmental factors (i.e., light- ing conditions in the workplace, display position, display characteristics, and image quality). 2 ese factors result in symptoms of eye strain, blurred vision, dryness, and musculoskeletal symptoms, such as neck, shoulder and back pain. 1 Ergonomic considerations are important for people with presbyopia who use digital devices, because spec- tacle lens designs for this population are often associ- ated with eyestrain and musculokeletal symptoms. Bifocal spectacles are typically designed to provide clear near vision in down gaze which may not be adequate, particularly for people who use desktop computers. 2 Multifocal contact lenses may provide an ergonomic benefit for these patients. Physical Ocular Changes in Presbyopia While people with presbyopia are experiencing visual and ergonomic symptoms of digital eye strain, they also are experiencing physical ocular changes. Age‐related changes in the lacrimal gland results in decreased tear production, and the length of the meibomian glands decrease gradually with age, which may affect the ocular surface and the tear film, including tear film breakup time. 3 D igital devices — and the thou- sands of apps available for them — have become integral parts of our lives, and their use is not limited to a particu- lar place, time, age group, or occupa- tion. Whereas, computers were once tied to the workplace and the workday, today, thanks to mobile digital technology, we can engage in work and leisure activities 24/7. Our reliance on digital technology has dramatically changed the way we use our eyes. Most people in their 40s and 50s spend more than 5 hours a day using digital devices, and more than 60% of them experience one or more symp- toms of digital eye strain, 1 which is just one of the vision- related challenges for presbyopic patients.
