Diabetes management has long relied on intermittent fingerstick blood tests and, more recently, continuous glucose monitors (CGM) that use subcutanous sensors. While these methods haved countless lives, they rein invasive, require regular calibration, and can cause discoult or skin irication. A growing body of research sustins that tear fluid glucose levels closely correle with with blood gluche, opening the doour tguly novaluy n-invasivyvine vine vorinviorg triphasting.
