Ultraviolet (UV) rays and chronic irritation to dust have been implicated in the pathogenesis of degenerative conditions of the cornea and conjunctiva like pterygium and pinguecula. It has been postulated that exposure to these environmental factors cause corneal and conjunctival drying by disruption of the tear film. While some researchers have found tear film dysfunction in eyes with pterygia and pingueculae, others have found no such abnormalities. The differences in findings may be due to different methods of investigation, or differences based on geography and climate.
