Continuous Social Media Scrolling Negatively Impacts Eye Movement
The cross-over study measured participants’ levels of musculoskeletal fatigue using a stationary bike in addition to their oculomotor function.
Sustained social media scrolling has a detrimental effect on eye movement, according to findings presented at the American Academy of Optometry 2021 annual meeting, held in Boston from November 3-6. Using an on-board application, researchers measured scrolling speed, and during 1 of the sessions, participants cycled on a stationary bike for 15 minutes at 60% maximum heart rate. When the near task was combined with biking, this effect was aggravated (peak velocity: 19% to 31%, inaccuracy: 16% to 21%), but there was no variability in saccadic latency across any experimental conditions.
