Are you one of those people who can't do without a cup of coffee in the morning? That kick in the cafe can do even more to wake you up in the morning. A study recently published in the journal Psychopharmacology shows that drinking coffee really helps your visual functions because it increases alertness and nudity detection for movement purposes. Coffee can also help improve your reaction times, if at all.

Researchers from the Waterless School of Optometry & Vision Science and the University of Granada collaborated on the research. Researchers know that caffeine increases the speed of rapid eye movement, so they want to further investigate the effects of caffeine consumption on dynamic visual acuity, the ability to recognize and recognize it in small details in business conditions. Dynamic skills for visual acuity are important in many everyday situations, such as crossing a busy intersection or looking for something on a board as you walk through the aisles of a supermarket, the researchers said.

Effects of caffeine intake

In the study, one group of participants took a caffeine capsule (4 mg/kg), while the other group took a placebo capsule. Using a computer test, their dynamic visual acuity was measured before and 60 minutes after ingestion.

According to the researchers, those who ate capsules from the café showed a more accurate and faster speed when recognizing lower speeds.

"Our findings show that coffee consumption really helps a person's visual functions by improving alertness and a sense of alertness," said Dr. Kristine Dalton of Waterless School of Optometry & Vision Science, cited in ScienceDaily.

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 recently published in the Psychopharmacology journal.
