|Stye on outer lid|
"What does it look like?" It looks like a pimple on the eyelid either on the inside or outside of the lid.
"What are the symptoms?" The first signs are swelling, redness and pain. The area will feel tender as well. Then a small pimple will develop in the affected area. Often there will be a yellow "tip" at the center. This is pus that has risen to the top.
"What causes a Stye?" A stye results from an infection of the oil glands of the eyelid that help to lubricate the eyeball. The infection occurs after these glands have become clogged. A stye can come from an infected hair follicle at the base of an eyelash. The bacterium staphylococcus aureus that is frequently found on the skin is responsible for 90%-95% of cases of styes.
