Eyeball issues

I'm having a reoccurring issue with my right eye. Every so often it turns red. So, I have one white/blue eye and one red/blue eye. No particular pain, oozing, gunk, soreness, just the beautiful color red. Wes and I got to talking about it tonight and we have noticed that the days it turns red are the days I do my swim workouts. So, what does that mean? I have no idea. Is it my goggles? Chlorine? Why is just one eye red, but not the other?

Has anyone had a on-again off-again red eye problem?
