April 26, 2018 (MedicalXpress) -- It may not replace prescription glasses, but a few bites of dark chocolate might offer a slight and temporary bump up in vision quality, new research suggests.
Heart-healthy compounds in chocolate called flavanols appeared to sharpen eyesight for a group of 30 healthy young adults in the new study.
The observed change in vision was small, but significant. However, the study authors stressed that it's too early for ophthalmologists to recommend chocolate as medicine for the eyes.
"The duration of these effects and their influence in real-world performance await further testing," said a team led by Dr. Jeff Rabin of the University of the Incarnate Word in San Antonio, Texas. His team published its results online April 26 in JAMA Ophthalmology.
