Abstract
Topical skin-barrier coatings degrade over time without visible indication, while sub-visual ultraviolet-induced dermal inflammation remains undetected prior to clinical presentation. In this disclosure, a wearable optoelectronic eyewear frame is configured with an outward-facing waveguide-coupled photochromic lens assembly and an inward-facing optical module housing a multispectral optoelectronic sensor array. Environmental ultraviolet exposure is determined by measuring light attenuation across embedded microscopic perimeter optical waveguides as photochromic lens density shifts. Concurrently, synchronized 365 nm ultraviolet-A and 850 nm near-infrared light pulses are emitted toward facial tissue by the inward-facing optical module. Reflected light is received by a micro-CMOS sensor equipped with a physical dual-bandpass filter to evaluate topical coating retention. Subdermal blood-volume pulse shifts are measured via nearinfrared photoplethysmography to identify capillary vasodilation. Processed telemetry and diagnostic alerts are transmitted via short-range or integrated wide-area wireless transceivers to external network gateways for proactive tissue protection.
