Google Glass restricts drivers’ peripheral vision

Google Glass could pose greater risk to drivers by obstructing the wearer’s right peripheral vision

Google Glass has come under fire for a range of privacy issues and its possible exploitation by media pirates, but now its potential to restrict the peripheral vision of wearers has now been flagged.

The warning comes from a study by academics at the University of California, reports the Telegraph, who used volunteers to test Google's headset. It was found that vision was significantly impaired from wearing the device, especially in the right hand corner where the display is situated.

Peripheral vision is important for drivers and cyclists, as it allows them to see oncoming vehicles.

Dr Edward Koo, clinical ophthalmologist at the University of California, San Francisco, said: "The Google Glass hardware produces a significant blocking effect of the right peripheral vision.

"The defect would not be compensated by the left eye and thus may negatively impact daily activities such as driving, cycling and running."

Comparing the results to those where the volunteers were wearing normal glasses, Google Glass was found to have much more impact on the peripheral vision of the wearers.

"In the UK, where the driving position is reversed, the potential blockage of right peripheral vision for on-coming traffic may be even more of a public safety hazard," Koo continued.

"The right peripheral field is also essential for many other activities such as providing the ability to perceive obstacles and hazards when cycling or jogging on the roadway."

Last month, a man was the first known person to be treated by psychiatrists for internet addition brought on by over-use of Google Glass.

Cinemas in the UK and US have made moves to ban the use of the head-mounted computers out of fear it may aid movie piracy and make it harder for staff to detect culprits.

A spokesperson for Google Glass commented on the new findings, saying: "Put on your favourite shades, glasses, baseball hat, or hoodie, and you'll quickly see that this study tells us what we already know; wearing something on your face or head may affect your peripheral vision.

"From the beginning, the Glass team has worked closely with a range of experts to develop a device that is safe for use, and after extensive study they have not found any safety issues when it's used correctly."
