Well, generally speaking, it will just take a few days for the eye pimple to go away. And you should know that eye pimple is actually caused by bacteria, an infection, and you may need antibiotics to treat it. And sometimes it will go away on its own. To treat it, the effective way you can do is just making sure your eyes are far from the bacteria, so that they can not be infected. Also, you can apply a hot, moist compress several times a day for at lease 10 minutes at a time. Just repeat it in some days. Also, you should not be stressed. Having a good rest is also effective. Anyway, just be careful about it.
