Did you know that dark chocolate might be temporarily good for your eyes? It is already known that it can improve your blood flow for a short while and the lead study author, Dr. Jeff Rabin of the University of the Incarnate Word in San Antonio, Texas wondered if that meant it also improved your sight. That left him with a question: How does consumption of milk vs dark chocolate affect visual acuity or contrast sensitivity within 2 hours of consumption?
So he came up with a study to put it to the test. In total there were 30 participants, 9 men and 21 women, who had an average age of 26 years. In two separate sessions they were given milk chocolate and dark chocolate and put through an eye exam to test how the two treats impacted their eye sight. The study showed that there was indeed some improvement within two hours.
The results of the small, randomized trial were published in JAMA Ophthalmology yesterday and you can find them here.
