The most accurate contact lens-type dosimeter in the world for measuring radiation doses delivered to the human body in Diagnostic Radiology and Radiotherapy. Unlike the conventional, less precise method of attaching a dosimeter to the skin around the eye, this approach involves inserting the dosimeter directly into the eye, enabling highly direct and precise measurements. This system scans and measures changes in the color of the radiation-sensitive layer in direct proportion to the radiation dose delivered during radiation therapy and diagnostic examinations. It is composed of a safe silicon material for the human body and is worn using the same method as regular contact lenses, providing convenience. Its ultra-thin design ensures that it can be used by patients without discomfort.
