Puffy red eyes can not be avoided after crying. This effect can last for as little as a few minutes or stretch on for a few hours. However, if you want to reduce them for a big moment, the best way is to lie down and give it a cold pack. In the same time, please put your fingers under icy-cold water or rest them on top of a ice pack. Then you could give your eyes a massage, starting at the inner corners of your eyes and ending at the outer corners of your eyes. You could repeat this process several times to help drain the fluid that has accumulated underneath your eyes and then the puffy red eyes will be reduced or disappeared.
