visine redness reduction eyedrops.

what happens is that marijuana expands your blood vessels, causing more blood to travel to your eyes, making them red. at least i think that's how it works...

anyway, most people get red eyes, but i know a few who do only on occassion. i dont know why, but it happens. you just have to roll with the punches and carry eyedrops with you just in case.

hope i helped.
