Tobii Pro Glasses 3

They offer the ability to conduct research on human behavior in different settings. The front-facing camera covers a wide field of view, while the eye-tracking technology integrated into the lenses allows the wearer an unobstructed view. This enables tracking of very wide angles and provides more comprehensive data on visual attention.
