I don't really know what to tell you, I use to get redeye but now I almost never get it. I think it has to do mostly with your smoking environment, if your in a small, cramped area with no good ventilation then you will most likely get redeye, but if your outside or at least in a well ventilated area, I really don't think that you'll have much of a problem with redeye.

I've never used eyedrops for redeye before, but I would think that they would do the trick if you really think it's that noticable.
