What are “smart glasses”?

“Smart glasses” are eyeglasses that have “built in” computer technology. They were first developed in 2012, when Google introduced the prototype named “Google Glass.” These glasses had a high resolution camera that was able to record and send pictures and videos via the internet. Initially, the glasses were used to train doctors how to perform various surgeries by showing the surgeon’s view of the procedure as recorded by the eyeglasses.

Over the years, many advancements have occurred and the technology has been refined. The glasses are now able to superimpose information onto the wearer’s field of view, allowing him or her to still be able to see through it if desired. Smart sunglasses are able to change the amount of tint and color to the lenses. Smart glasses use WiFi or cell phone technology to access the internet ‘hands free” via voice commands or by touching the control bar on the eyeglass temples along the side. Smart glasses utilize apps similarly found on smartphones to perform such activities as fitness tracking, GPS location and directions, checking email, sending texts, taking and sending videos and sharing photos.

The speaker for wireless audio inputs and cellphone reception rests on the end of the temple. Audio can be transferred to the ear via bone conduction instead of air conduction through the ear canal. Bose has developed smart glasses with a high quality audio system with hidden headphones and no earbuds or bone-conduction. Smart  glasses can use Bluetooth technology as well. Other smart phones have been produced by several companies including the Amazon Echo Frames, Facebook Smart Glasses and the newly released RayBan Stories Smart glasses. Battery time continues to improve and the weight of the frames continues to get lighter. The frames also have become much more stylish than the bulky prototypes that first came out. Initially, Google glass had a price tag of $1500 and this was too expensive for most consumers. It was taken off the market after only 18 months. Now these glasses can often be purchased for less than $300.

 The concept of hands free access to the internet and many computer applications through the use of eyeglasses is clearly an exciting one. However, smart glasses have considerable potential to distract the wearer, which could increase the danger to themselves and others, especially while driving. Therefore, as with texting messages, use your device when appropriate and be aware of your surroundings at all times to ensure your safety and the safety of others as well.
