Coffee time: Caffeine improves reaction to moving targets
That morning coffee might be even more helpful than you think.
In the first study of its kind to explore caffeine’s effects on dynamic visual skills, researchers concluded that caffeine increases alertness and detection accuracy for moving targets. Caffeine also improved participants’ reaction times.
Visual acuity, also known as clarity of vision or sharpness of vision, refers to a person’s ability to detect and recognize small details and can be measured under static (stationary) or dynamic (moving) conditions. While both static and dynamic visual acuity provide important information about how we interact with the world around us, dynamic visual acuity skills are especially important in the many daily activities in which we, or objects around us are moving.
The study, Effects of caffeine ingestion on dynamic visual acuity, co-authored by Waterloo’s School of Optometry & Vision Science’s Dalton, and the University of Granada’s Redondo, Raimundo Jiménez, Rubén Molina and Jesús Vera, was published in the Journal of Psychopharmacology .
