your eyes serve as a good indicator of your liver's health. if your eyes are red then it probably means that something drastic happened inside your liver. if you have a lot of Gallstones you will notice red eyes after meals taht contain a lot of fat, because bile is pumping but stones are trapped and congested inside causing toxins to be reabsorbed. i wouldn't worry about red eyes after flushes because that's just a sign that the liver is overloaded. if it stays bloodshot for a few days.. then that might be a problem. but if it's clears up then it's no biggie.
