Since you are asking a population-based question, then each individual here can’t really say whether they sneeze more often since no one person can compare themselves directly to another person. For example, I have dark eyes and sometimes sneeze when I go outside. That doesn’t make a trend, even if my neighbor has light eyes and sneezes every time. All I can say is that I sometimes sneeze.
I would be interested to know what exactly you noticed? You’ve seen a few people with blue/green eyes who sneeze a lot? Is that it? I have never heard of an association between allergic rhinitis and eye color, nor is there a known association between eye color and atopy (allergy) in general.
In the future, if you want to ask this question again, perhaps you might consider another way. For example, you could say, I want to conduct a small epidemiologic study. What is your eye color? Do you sneeze a lot and/or have allergic symptoms? You can then use simple statistical analysis to determine whether there is an association.
