Clear lenses
Face the camera directly and move light sources so they do not reflect over the eyes. A small angle change can remove glare without hiding the face.
Frames
Frames that cross the eyelids or cast a strong shadow can reduce signal stability. Check the live reading before relying on a session.
Tinted lenses
Dark tint and mirrored coatings may prevent ordinary cameras from seeing the eyes. Some infrared systems may perform differently, but support should never be assumed.
Sunglasses while driving
Do not remove required eye protection or adjust eyewear while moving. If the app cannot see the eyes, treat monitoring as unavailable.
Sensitivity is not visibility
Increasing sensitivity cannot restore detail the camera cannot see. Fix the angle, light, distance, or eyewear condition first.
Platform variation
Test the exact device and glasses combination because mobile and desktop detection backends are not identical.
