Reaction and vision acuity may improve after caffeine consumption.
Scientists have found that caffeine can improve the reaction and visual acuity of humans. Reaction and vision acuity may improve after caffeine consumption.
In the first study on the effects of caffeine on dynamic visual skills, researchers concluded that caffeine increases attention and accuracy in identifying moving targets. Caffeine also improved the reaction time of participants .

“A lot of what’s going on in our environment is moving – for example, you’re trying to cross a busy intersection as a pedestrian or you find something on a shelf as you walk down the aisles of a grocery store,” said Dr. Christine Dalton of the School of Optometry and Visual Science. Waterloo. “Dynamic visual acuity testing can provide more information about our functional characteristics in these scenarios than traditional static visual acuity measurements.”
On two days, half of the study participants took a caffeine capsule (4 mg / kg) and the other half took a placebo capsule. Using a computer-based test developed and approved by the University of Waterloo, each participant’s dynamic visual acuity skills were measured before and 60 minutes after caffeine intake.
The researchers found that participants who took caffeine capsules showed significantly greater accuracy and faster speed in determining smaller stimuli. Caffeine has a positive effect on the processing of incentives and decision-making by participants. Eye movement speed and contrast sensitivity, which affect dynamic visual acuity, were also sensitive to caffeine consumption.
