Hospital patients who wear tinted spectacles--physical sign of psychoneurosis: a controlled study.

The wearing of tinted spectacles by patients is often said to be a marker of psychopathology but without supportive evidence. To investigate the validity of this observation the personalities of 20 medical hospital patients who wore tinted spectacles were compared, by means of a self-report inventory, with those of 20 controls who were age, sex, and diagnosis matched. There was a significant increase in the level of psychopathology in the tinted spectacle group, both in terms of an index of global psychological distress; the General Severity Index, and nine primary symptom dimensions measured by the inventory.
