Chances are high you know someone with diabetes. My dad is diagnosed with it and gives himself an insulin shot each day. I have a young nephew who suffers from it as well. People with diabetes have the daily challenge of keeping their blood sugar levels in check, which means monitoring what they eat, when they eat, and how much they eat, among other things. It's a bum rap, but to make things easier, Google has begun testing a smart contact lens that measures glucose levels using a miniaturized sensor embedded between two layers of soft contact lens material.
