As times change, the way we interact with technology also changes. From rotary dial telephones to the era of smart watches and now smart glasses, there has been tremendous progress in optimizing technology for convenience.

With the evolution of the Metaverse, smart glasses are poised to be among next big technologies to develop. But first: what are smart glasses? 

For centuries, the primary purpose of eyeglasses was to correct, restore and improve vision to 20/20 or close to it. Smart glasses introduce another leap in convenience by offering the capability to bring the technology in our smartphones and computers directly to our eyes and ears.

The devices, worn like regular glasses, allow you to view and respond to your smartphone for calls, messages, emails, listening to music, using navigation, talking to a voice assistant and much more.

Google introduced the first smart glasses with Google Glass in 2013, in line with the movement towards the Internet of Things (IoT). Although Google Glass is considered a commercial failure, it opened the world to the potential of smart glasses.

Today, countless eyeglass makers and internet pioneers are joining forces to innovate and grow the field. Just as we cannot imagine living without a smartphone and a laptop today, smart glasses might move from being a nice-to-have accessory to a versatile tool for everyday use.

In this article, we will take a deep dive into the best smart glasses available today, types of smart glasses and how they work, current uses and future applications of smart glasses, and the challenges facing the adoption of smart glasses. We will also answer frequently asked questions regarding smart glasses.

Types of Smart Glasses

Below are the various types of smart glasses available in the industry. 

  • Monocular Smart Glasses. These are head-mounted displays (HMDs) that consist of an optical engine positioned on one of the lenses. Although the augmented information is located outside of your line of sight, it is like having a see-through smartphone. Common examples include; Google Glass, Lumus Sleek, Optivent’s Ora-2, and Vuzix M300
  • Binocular Smart Glasses. They consist of two transparent displays with an optical engine in front of each eye that gives users stereoscopic vision. The information is displayed just out of the line of sight on both eyes. Common examples include; Epson Moverio, SONY SED-E1, and ODG R-9.
  • Audio Augmented Reality Smart Glasses. Although augmented reality is typically associated with visuals, these glasses utilize sound-based AR. They combine information collected from attached motion sensors and phone GPS and can pipe sound directly to the user’s ears. The best example is the Bose Frames
  • Immersive or Mixed Reality Smart Glasses. These devices are fully immersive and consist of stand-alone systems that allow you to render 3D objects on board. They come with 3D sensors that make sense of your surroundings and accurately overlay computer-generated objects naturally. Examples include Microsoft HoloLens and ODG-9 smart glasses. 
  • Mixed Reality Photo Projection Action. While other types of smart glasses use a screen placed at a fixed distance from the eye, this type aims to project photons directly into the user’s eyes. This will fix a common drawback of existing AR smart glasses by giving users an enlarged field of view. Magic Leap are the leading brand on this technology. 

What Do Smart Glasses Do?

Different smart glasses accomplish different tasks depending on the manufacturer. However, generally, smart glasses aim to provide life monitoring services, as well as provide a means for taking more authentic photos and video clips. They can also be equipped with augmented reality technology, intended to assist you with your everyday home and business life. Expectedly, different models incorporate different technologies depending on the critical focus on the device. You will find models with a different number of cameras, wireless connectivity modules, GPS sensors, microphones, speakers, buttons, etc. 

How Do Smart Glasses Work?

Smart glasses work through a combination of display, sensors, and accelerometers, coupled with internet connectivity and smart software. Users have different ways of communicating with the device depending on the model, including touching, tapping, swiping, or voicing requests/commands. The controls can be embedded into the glasses themselves or incorporated into a handset – or both. Some pioneering alternatives can recognize gestures, including head, eye, and hand movements to activate the device. 

History of Smart Glasses

The history of smart glasses can be told through the countless prototypes and production units of smart glasses that emerged over the years. And the beginning may surprise you.

In 1967, computer scientist Ivan Sutherland created the Sword of Damocles with his students. Although rudimentary in its form and function, the device is widely regarded as the first-ever virtual reality head-mounted display.

From the 1980s through the 1990s, a Canadian researcher developed his WearCamp (wearable computer) solution that gave rise to the computerized smart glasses we see today.

The first-ever attempt at a widespread consumer product in smart glasses came in 2013 with Google’s Smart Glass. Although the product did not achieve the success Google hoped for, it gave companies the confidence to work on more easily adoptable types of smart glasses.

Current Use of Smart Glasses

Smart glasses can do a variety of things, including:

  • Send and answer messages
