Researchers at University of California, San Francisco, found that wearing Google Glasses has a drawback. Namely, it interferes with your peripheral vision.

This could negatively compromise your daily activities such as driving, playing sports and even walking down the street safely.

A test was conducted comparing performance on visual field tests with Google Glass versus regular eyewear to examine their effect on visual function. What they discovered was "significant scotomas (blind spots)" in all three participants wearing Glass, "creating a clinically meaningful visual field obstruction in the upper right quadrant."

According to a news release about the study: "Defects were induced by the Google Glass frame hardware design only and were not related to a distracting effect of software-related interference."

Meanwhile, a separate study from the University of Central Florida recently found that Google's high-tech headpiece is a clear distraction to drivers.

Some states are considering legislation to ban the use of Google Glass while driving.
