In 2025, tech giants decided smart glasses are the next big thing

There's a growing sentiment that gadgets have gotten boring. And while I don't fully agree, I understand why people might feel that way. Just think about some of the novel device types that companies have tried to push since the original iPhone came out.

3D TVs were a massive flop and tablets still feel like extra-large smartphones despite Apple's efforts to prop them up as laptop replacements. Meanwhile, even with huge technological advancements over the last decade, VR headsets remain relatively niche due to factors like high prices and a lack of compelling content. And although big names like Google, Microsoft, Meta and others continue to dump billions into AI development, the first wave of dedicated AI devices was an abject failure.

When you think about it, the only new(ish) class of gadget that has made major inroads to the mainstream market is smartwatches. That said, because they've evolved into wearable health and fitness sensors instead of the wrist-based computers that many once thought they would be, they haven't really disrupted our lives like the personal computer and smartphone did. But that seems poised to change because the tech giants have decided that smart glasses are going to be the next big thing.

Headsets versus smart glasses, what’s the difference?

At this point, you might be saying, "Wait, hold on. Aren't VR headsets and smart glasses kind of the same thing?" Well, yes and no. Both types of gadgets require similar software and hardware, but they utilize them in very different ways. Not only are VR goggles typically much bigger and heavier, they also provide a more isolated experience that can make it feel like you've been transported to another world.

Sure, most modern headsets have exterior cameras that support some level of mixed reality (blending virtual graphics with physical objects) or let you peek quickly into meatspace (passthrough view) for when you need to get a drink or acknowledge other humans in the room. But in many respects, that closed-off feeling is the goal because it creates the ideal environment for playing games, taking virtual meetings or modeling 3D objects without real-world distractions. Furthermore, while many headsets like the Vision Pro and the Meta Quest 3 can function as standalone systems and support accessories like controllers or other motion trackers, they can also be tethered to a nearby PC for enhanced functionality.

On the other hand, the default use case for smart glasses is a mixed reality environment where the spectacles can overlay helpful info or messages while you stay active and aware of your surroundings. Notably, while smart glasses might come with lenses or clip-on attachments that allow them to get darker or serve as sunglasses when you're outside, there typically isn't a way to completely block out the world like you can with a headset, mostly because that's simply not the point. And even though most smart spectacles can be paired with a phone to get access to mobile data or notifications, they're generally not meant to be tethered to a PC full-time (though there are some exceptions). The goal for smart glasses is more to provide a mobile-first heads-up display that augments what you see with your eyes instead of replacing things entirely with a digital environment.

OK, but what makes you so sure that smart glasses are "it?"
