Doctors harness light for disease diagnosis through innovative technologies

Doctors use light in various ways to diagnose diseases, from eye exams to blood tests and medical imaging. New technologies allow for quicker, on-the-spot tests, improving patient care compared to traditional lab analyses. Point-of-care diagnostics, like pulse oximetry, provide immediate health insights. Automated blood analyzers use light to assess blood samples, detecting health markers and potential diseases rapidly. Advancements in fiber-optic technology enable high-resolution imaging inside the body. Future developments include wearable sensors and AI tools that enhance disease detection through light-based methods.
