Google Contact Lens is a smart contact lens project announced by Google on 16 January The lens consists of a wireless chip and a miniaturized glucose sensor. A tiny pinhole in the lens allows for tear fluid to seep into the sensor to measure blood sugar levels, contact lens wear and diabetes.
The contact lens wear and diabetes lie outside of both the pupil and the iris so there is no damage contact lens wear and diabetes the eye. The controller will gather, read, and analyze data that will be sent to the external device via the antenna.
Power will be drawn from the device which will communicate data via the wireless technology RFID. On 16 January Google announced that, for the past 18 months,  they had been working on a contact lens that could help people with diabetes by making it continually check their glucose levels. The idea was originally contact lens wear and diabetes by the National Science Foundation  and was first brought to Microsoft.
They also mentioned that the project is currently being discussed with the FDA while still noting that there is a lot more work left to do before the product can be released for general usage, which is said to happen in five years at best,  and that they are looking for partners who would use the technology for the lens by developing apps that would make the measurements available to the wearers and their respective doctors.
Larry Levin commented the benefits of being able to offer his patients a pain-free alternative to either pricking their fingers or using a continuous glucose monitor. However, experts in the field  have cast doubt on the ability of the amount of glucose in tears as measured by the contact lens to correlate strongly with blood glucose of the user. Many reported studies show, at best, contact lens wear and diabetes, a weak correlation that would not meet accuracy requirements for glucose monitoring.
