Can Participants Wear Prescription Glasses or Contact Lenses While Using Tobii Pro Glasses 3?
Yes, Tobii Pro Glasses 3 are made to fit a wide range of users, including those who wear contact lenses or prescription glasses. Because of this, the system can be used in studies with participants from various age groups, occupations, and clinical populations without requiring them to take off their corrective eyewear.
Compatibility with Prescription Glasses & Contact Lenses:
The glasses capture eye movements across a variety of eye features and face geometries by utilizing Tobii's binocular infrared eye tracking technology in conjunction with a patented 3D eye model.
During setup, researchers perform either:
One-point calibration
Automatic calibration
This ensures that gaze data is accurately mapped to the participant's field of view.
In most cases, participants wearing:
Contact lenses
Standard prescription spectacles
can be calibrated successfully and produce high-quality recordings.
Factors That Can Affect Tracking Performance:
Like any infrared eye tracker, tracking performance can be affected by a number of conditions, such as:
Highly reflective lenses
Strongly tinted glasses
Mirrored coatings
Excessive eyelashes
Challenging lighting conditions
These factors may reduce the quality of eye images captured by the sensors.
Best Practices Before Data Collection:
Researchers are encouraged to:
Verify tracking quality during calibration
Perform a short pilot recording before beginning the experiment
The Tobii Controller App allows the operator to:
Review eye images
Monitor tracking quality in real time
This helps identify potential issues before data collection starts.
Maintaining Tracking Accuracy During Natural Movement:
Because Tobii Pro Glasses 3 incorporates:
Automatic slippage compensation
Automatic parallax correction
the system is more tolerant of natural participant movement than many conventional wearable eye trackers.
These technologies help maintain gaze accuracy throughout the recording session, even when participants are:
Walking
Working
Interacting with objects in real-world environments
Summary:
Participants who wear contact lenses or prescription glasses can benefit from Tobii Pro Glasses 3. The system can generate high-quality eye tracking recordings while allowing for natural participant movement in real-world research environments thanks to binocular infrared eye tracking technology, a patented 3D eye model, one-point or automatic calibration, automatic slippage compensation, and automatic parallax correction.
