Abstract
A noseshade for monitoring exposure to UV radiation comprises a contoured portion (100) having a clip (102) for attachment to a pair of glasses. The contoured portion of the noseshade incorporates a digital LCD (104), an information-display key (106), and input keys (108 and 110). A UV-enhanced photovoltaic photodetector (122) having a built-in amplifier (124) is mounted into the contoured portion of the noseshade, which also houses solar cells (112 and 114) and a microcontroller (118). The inner portion of the clip contains a pressure-sensitive switch (107) for activation of the solar cells.
