Before you buy a new pair of eyeglasses for sale, here’s delicious news for your eyesight: dark chocolate might be very helpful to your vision.
Albeit still the trial had a limited number of participants, some research from the Incarnate Word Rosenberg School of Optometry in San Antonio, Texas found out in a series of short experiments that dark chocolate consumption improves visual acuity.
In the experiment, two groups were tested. One of the groups had milk chocolate and the other group had dark chocolate (72% cacao bar). They were given visual acuity exams 2 hours after eating. Both groups performed better than people who did not previously eat chocolate. The dark chocolate control group had better results. The milk chocolate group can clearly see from 20 meters away some text that can be seen at 15 meters with regular vision while the dark chocolate group can read from 20 meters some text that regular vision can only scope out at 12 meters.
If you think dark chocolate is enough reason to not grab eyeglasses for sale yet, hold your horses. The test had yet to look into long term effects. One of the hypotheses of why this happens is because dark chocolate enhances blood flow to central and peripheral nervous system with cocoa flavanols.
Before you get any ideas and start thinking that maybe coffee does the same thing since caffeine is supposed to boost your heart rate and energy levels, a research finds that too much coffee might actually harm your eyes. Data from The Association for Research in Vision and Ophthalmology found a correlation between individuals that drink 3 cups or more coffee having a higher chance of developing exfoliation glaucoma. Even though caffeine does improve circulation and has an effect on the nerves like dark chocolate, too much of it may have an opposite effect on your eyesight.
In any case, you can try having a bar of dark chocolate to your pleasure. It has less calories than it’s sweetened milky counterpart, it’s good for your heart, and it gives you a vision boost. If you really need to buy eyeglasses for sale though, dark chocolate can’t help you, so you better see your ophthalmologist for your prescriptions.
