title: Lost contact lens masquerading as an orbital mass.
abstract: A 30-year-old woman presented to the orbital clinic with a 4-year history of a mass in her left upper eyelid of unknown aetiology. Eyelid eversion revealed an embedded hard contact lens, which was removed under local anaesthesia. The patient made a full recovery but this case highlights the need for a careful history in contact lens wearers and a full examination including double eversion of the upper eyelids.
