These Imaginative Inventions Actually Exist…

Smart Lenses For Diabetics

Here’s one of the best inventions of the 21st century that could literally save lives. The pharmaceutical company, Novartis, announced a few years ago that they were developing special contact lenses.

Of course, these help people see better with their prescriptions. However, they can also help monitor blood sugar levels via the tear ducts of the user. This could be invaluable for people suffering from diabetes and could potentially save their lives. They are designed to change color if glucose levels become imbalanced.
