Audio / AI glasses
Speakers and microphones in the temples connect to a phone or onboard processor. Voice input can trigger calls, media controls or AI services.
How do smart glasses work?
They combine ordinary eyewear with one or more digital systems: audio, cameras, displays, sensors, processors, wireless radios and companion software.
Camera AI glasses
A forward-facing camera captures photos/video and can provide visual context to AI systems. Processing may happen partly on-device, on a phone or in the cloud.
HUD glasses
MicroLED or similar display engines send light through waveguides or optical combiners so text and simple graphics appear in the user's field of view.
Wearable display glasses
Micro-OLED or related displays receive video from a phone, handheld or PC. The glasses act much like a private monitor, sometimes with onboard spatial stabilization.
AR glasses
More advanced systems combine displays with cameras or tracking sensors so digital content can respond to head movement or the environment.
Power and connectivity
Some glasses have their own battery. Others, such as many display glasses, draw power from the connected device. Bluetooth, Wi-Fi and USB-C are used for different jobs.
The key is the architecture
Two products can look similar but work completely differently inside. That is why GlassesDB compares category, display, camera, audio, AI, weight and compatibility separately.
