Thanks for sharing. Actually, my third child (DD) gets random (usually only one or two) hives on her face as well. However, it only happens a few times a year and most of the times we can't tie it to any specific food. Since it is only one or two and goes away the same day, we just keep an eye on it and generally don't give her benadryl for that. Her obvious allergic reactions, which we can generally tied to a specific source, usually include other symptoms as well as more severe hives with swelling.
There are so many possible combinations of symptoms that it can make it confusing to track. I know that I would not have known to connect itchy eyes with a food allergy, but that's because in my DS' case, he usually has other issues causing itchy eyes.
