US Patent 11644361 Eyewear with detection system

Eyewear having monitoring capability, such as for radiation or motion, is disclosed. Radiation, such as ultraviolet (UV) radiation, infrared (IR) radiation or light, can be measured by a detector. The measured radiation can then be used in providing radiation-related information to a user of the eyewear. Motion can be measure by a detector, and the measured motion can be used to determine whether the eyewear is being worn.
