During World War II, the British Royal Air Force had a secret “weapon.”

They consumed a special type of berry jam which improved their night vision.

Thanks to the power of the inky-blue fruit, they were able to bomb the enemy with devastating accuracy.

This unusual berry still sharpens vision today.

Studies from the Journal of Medicinal Food prove that. 

They found that a component found inside this berry provides protective effects against macular degeneration, glaucoma, and cataracts.

In fact, in a study in people with glaucoma, taking this berry daily improved vision by an astounding 30%!
