What is a stye? A stye or hordeolum is a small, painful lump on the inside or outside of the eyelid. It is actually an abscess filled with pus and is usually caused by a staphylococcus bacteria eye infection. Styes are common with most people experiencing one or two of them at some stage in their life. Styes are usually visible on the surface but can appear deeper inside the eyelid.
