It works by constrincting the blood vessels in your eyes, causing less and less oxygen to be able to get to your eyes. Some vessels can even collapse on theirself.
Opcon-A is what my ophthalmologist recommends for allergic redness/itching. It burns, but it does work.

Way of the Leaf, I've often wondered where you get your facts. They're so frequently wrong. Vaso-constriction does indeed shrink blood vessels, but collapse is a very rare occurrence, particularly with over-the-counter opthalmic solutions that target tiny capillaries.
