How Will Google Glass Affect Our Vision?


Ever since the first Google Glass concept video (above) was posted in in early 2012, I have been excited about the technology and it potential uses. The idea of hands-free video recording and real-time, hyper-local, cloud-based (and other fancy hyphenated terms) interaction is extremely appealing.

But although Glass may be extremely cool, there are concerns about privacy which are now being addressed. Although it isn’t much different from a cellphone camera, something about a person wearing them as glasses is creepier. Some businesses have already banned Glass, but that may be more for the attention than anything else.

Additionally, possible visual issues may arise from Glass use. There doesn’t appear to be issues with eye damage from wearing Glass. There may be minor eyestrain for some people from looking above the horizon. The biggest the splitting of visual attention. After all, it is only possible to pay attention to one image at time. It is this attention splitting concern that is responsible for warning against wearing Glass while driving and other potentially dangerous activities.

There have been a few recent videos out that addressed Glass and vision. The first was taken by Trey Ratcliff of his Optometrists, Dr. Danielle Pretty. She describes Glass and her impressions of the location and effect of Google Glass display.


The second video comes from Dr. Isaac Porter, of Lowry Porter Ophthalmology who interviews a Glass Explorer and talks about the visual adjustment to Glass and shows the first formal visual field assessment with Glass on.


Are you a Glass Explorer? I’d love to check it out and talk with you about the visual implications of Glass – connect on GPlus, or email me at!


All the best!

Dr. Nate Interviewed about Google Glass

If you have even a tiny interest in either technology or eyewear, then you sure have heard about Google Glass. If you aren’t familiar, they are glasses that capture and display information for you. Think Geordi Laforge’s visor from Star Trek Next Generation. Better yet, watch this concept video from Google:


Mashable interviewed me to get an eye doctor’s take on the new glasses. While very few people have seen working examples of Google Glass, including me, I have read quite a lot about them and talked to people with experience with it. While the technology is undoubtedly very, VERY cool, there are two concerns from a visual stand-point.

The first is physical – our eyes are not best suited to the set up of the device. Even though it is a Heads Up Display, you do have to look up and out at the image, potentially causing eye strain and can result in symptoms including headaches, burning, gritty eyes, back and neck pain and short-term difficulty focusing in the distance after long periods of computer work.

The second is mental – people can only pay attention to one thing at a time. So if they are watching their Google Glass display, they are not watching the world around them. Additionally, some people have a very hard time simultaneously processing visual information while controlling their body movements (such as walking).

Why Google Glass Could Be Bad For Your Eyes

I can’t wait to get a pair and try them out for myself. Google is running a contest to select people who want to purchase Google Glass early.
