Thanks...I've used them for years and daily. I have noticed a red splotch on my eyes at random areas on occasion. And sometimes, after not dosing my eyes for say 5 hours, they'll well up and start watering and turn all red. Like in the middle of talking with somebody. Not cool. I can't stop using them now because I'll look SOOO blazed when I don't drop. Anybody know of alternatives to eye drops in eliminating redness?
