For those who were a little scared by the slight sting of the usual device for measuring blood glucose, a curious alternative is being developed. Researchers have created contact lenses that can identify diabetes by analyzing tears. The process does not depend on batteries, like usual devices, and gives its result through a change in color.
These lenses use the natural chemistry of tears to indicate glucose levels in the body, making the process safer and more comfortable compared to previous designs with electronic components.
The lenses feature electrodes that react to glucose byproducts in tears, changing from colorless to blue in response to the glucose concentration. The intensity of the color change in turn reflects the levels of the substance. Tests have shown that these lenses can detect a wide range of glucose concentrations.
A notable feature is the real-time monitoring capability. Users You can simply put the lenses in in the morning and check the colors every 20 minutes. The technology also takes color-coded photos of the electrodes, allowing tracking over time.
The researchers point out, however, that there are challenges to be overcome, such as the fact that glucose levels in tears lag behind blood levels. Commercialization to the general public also promises to be difficult, but the innovation has the potential to significantly improve glucose monitoring for people with diabetes.
