What Are Smart Glasses?

Smart glasses are eyewear with built-in electronic or connected features, but the specific functions vary from one product to another. Some focus on open-ear audio and hands-free calls. Others add a camera for photos or video. AI-enabled models can add voice assistance, visual recognition, translation, or other software-driven functions. Display-equipped glasses can put visual information or a wearable virtual screen in the wearer’s view.

A product does not need all of those capabilities to qualify as smart glasses.

The term is best understood as an umbrella category rather than a fixed specification. A camera is not required. AI is not required. A visible display is not required. Augmented reality is not required.

That distinction matters when shopping because two products labeled “smart glasses” may be designed for completely different jobs.

This guide focuses primarily on consumer smart glasses. Professional and enterprise smart-eyewear systems also exist, but they may have different hardware, software, security, and workplace requirements.

What Can Smart Glasses Do?

The answer to “what do smart glasses do?” depends on the product.

A useful way to compare models is to separate the individual capabilities rather than assume that one “smart” label includes everything.
