It would appear that Google foresees a future in wearable computers and is already spending its research resources to that end. The smart contact lens are still a research project at Google X, the division where some of the search giant’s most ground-breaking research work is being done.
According to Google, it is still working on the smart contact lens and in the future, intends to pack a small LED light in it. This light would be used as a signal to the wearer if his/her glucose levels dip too low or rise too high. It remains to be seen whether this light will be used as simply a blinking signal or the information will be relayed from the contact lens to another machine or device, such as a smartphone.
Interestingly, the company is also in talks with FDA over the smart contact lens and may soon grab a commercial and medical approval for the product. That clearly shows that this is not just a research project and Google has all plans of spinning the smart contact lens into a commercially viable product. Put it next to Google Glass and you realize that the company is planning to dominate the coming era of wearable computers.
