What is a chalazion?
A chalazion is a painless, hardened lump which forms when a meibomian gland becomes blocked. This gland produces part of the tear film which covers the eye and keeps in healthy and moist. Some chalazia get better without any treatment. If the problem continues the blockage needs to be treated by a qualified optometrist or medical practitioner. Sometimes, the gland may become infected and a stye may develop.
