Abstract：Objective To evaluate the effectiveness and safety of mobile flashlight from the perspective
of medical device quality control so as to explore its potential in mobile health. Methods Taking
mobile flashlight as the light source of ophthalmoscope, its optical radiation risks were evaluated. Using
flashlight as the light source and a fiber optical spectrometer as the detector, measurement of reflective
oximetry was made to analyze the signal. Results The optical radiation risk of mobile ophthalmoscope
mainly depended on the blue light, and the application scenario in this paper was considered as Class 2
equipment according to ISO 15004-2:2007. The reflectance signal on tissue generated by the flashlight
was useful for oximetry measurement. Conclusion As a common personal belonging and basic element
in mobile health, the flashlight in cell phones had medical application effects and security risks, which
should draw more attention from the research ＆ development departments to the regulation authorities.
