A marble used as a low-vision reading aid: a case report.
An unusual low-vision remedy was encountered in which a simple dime-store marble was used in near vision tasks. Although the marble was found satisfactory as a low-vision aid, the patient could be better assisted with a commercially available magnifier of lesser dioptric power. This case serves to demonstrate a patient's ingenuity in independently solving his own low vision problem.
