A warm tea bag works better, carlton. Put it in a cup, pour hot water over it and let it stand for a few minutes. Swirl round, take the teabag out, squeeze, and when cool enough, apply it to the stye. Do that a few times a day.
A spoon also works sometimes, as does rubbing with a coin, but be careful if you use either of those methods, as the skin around trhe eyelids is very delicate.
Finally, keep the eye area very clean. Bathe with warm water, dabbing carefully over the infected part of the eye.
