A stye (hordeolum) is a small, painful bump at the base of your eyelash or under the eyelid. It often causes the eyelid to swell. A chalazion is a larger red lump on the eyelid. A chalazion is not usually very painful, and it usually doesn’t cause the entire eyelid to swell. Treatments range from warm compresses to medication, based on what your ophthalmologist sees. In some cases, surgery may be needed to drain the stye or chalazion.
If you have any questions about your eyes or your vision, speak with your ophthalmologist. They are committed to protecting your sight.
