By Cat DiStasio

Modern technology has brought us many things that make our lives easier. Some of them, like meal delivery at the click of a button and streaming movies over the internet, have contributed to making people lazier, more sedentary and less fit. Luckily, there are lots of cool gadgets that help encourage healthy habits. You're probably already familiar with run-of-the-mill activity trackers that monitor your heart rate, daily steps and calories burned, but the devices we're spotlighting today take health technology a step further by contributing to a greener world -- and in some cases even saving your life.

A contact lens that checks your blood sugar

From the depths of the Google X lab come all manner of innovations, ranging from kite-like wind turbines to greener building practices. This smart contact lens can actually monitor the health of people with chronic diabetes. The lens uses a tiny wireless chip and a miniaturized sensor to measure blood glucose levels once per second. A lens like this -- the cost of which is unknown -- could replace other types of blood glucose-monitoring systems, which are often irritating, time-consuming and sometimes painful to use. Google hopes to make the disease easier to manage so that diabetics can enjoy longer, happier lives.
