Recently there have been some questions about comments I made about eye discomfort and Glass. I wanted to clarify a few points based on the research and evaluations I’ve done with head-mounted-displays (HMDs) in general and with Glass specifically:
• First and foremost, I have researched both HMDs and Glass for years and have found no evidence of any health risks.
• Relative to the thousands of people using Glass, very few have reported that they’ve had an issue with eye discomfort or headaches.
o For most, the discomfort usually goes away after a day or two as they get used to the device.
o This adaptation phenomenon is similar to the initial discomfort some people have when wearing a new pair of prescription glasses, which eventually goes away.
o Like any piece of technology, from TVs to smart phones, it’s important that people find what’s comfortable for them. That’s why Explorers are encouraged to ease into Glass.
Glass is designed for micro-interactions rather than long interactions like reading a book or watching a movie. The Glass team makes this clear in their Help Center.
