Diplomates in the Contact Lens Section of the American Academy of Optometry were surveyed to determine how they managed contact lens patients with pingueculae or pterygia. Responses indicated that many patients with these conditions can be successful contact lens wearers. Specific management techniques used by these practitioners are reported.
A 70-year-old male experienced unilateral monocular triplopia of lenticular origin. The images formed a nearly equilateral triangle and were equally clear. It was noted that the images were formed by sections of the crystalline lens whose borders were parallel to the orientation of the anterior Y-sutures.

Examples of confusing field descriptions in current literature are cited, with a recommendation for improved visual field notation.
