The utilization of a temporal mirror coating on the back surface of the lens as a field enhancement device

A 37-year-old male had a right homonymous hemianopia due to trauma. During his initial low vision assessment, a small clip-on mirror was dispensed to help him compensate for his field loss. At follow-up, he reported satisfaction with the mirror. He also reported that novelty "look behind you" sunglasses were beneficial to him and less conspicuous than the clip-on mirror. He requested temporal mirror coating on otherwise clear lenses so that he could utilize the glasses at night or on cloudy days. We fabricated this for him and also mounted a small mirror nasally within the vertex distance behind his frame. The fabrication of the two devices will be discussed as well as a comparison of these three field enhancement devices.
