If you get a bad case of the red eye, buy some Rohto eye drops. They are like 5 bucks for a little bottle, but i usually drop one in each eye just before i toke and i'm usually okay, and if i get bad one drop will fix it instantly. beware tho, it may burn the first time. i have contacts and i use it, and nothing bad has happnd. its great for getting high before school to keep your eyes white all day and that kind of stuff.
