Compass is still being developed and is effectively in beta. Some content and features may be incomplete, change, or not work as expected.
Content is anchored to trusted sources where available, but Compass has not yet been clinically reviewed. It provides general information rather than medical advice.
Feedback helps us identify gaps, errors, usability problems and opportunities to improve Compass over time.

Eye-Tracking Devices
- What affects how well eye-tracking works for someone?
Supports this
“Dry eyes, eyelid problems and glasses can all affect eye-gaze tracking. Glare on glasses is usually workable, but untreated dry eye that damages the cornea can end someone's ability to use an eye-gaze device.”
Has a dedicated section on eye health with eye gaze. It says that if dry eyes progress to loss of the tear layer and damage to the cornea, a person may lose the ability to use an eye-gaze device entirely, and that many people do not report dry eyes until irritation has already started.
If you develop dry eyes, lose your tear layer, and develop damage to your cornea, you may lose the ability to use an eye gaze communication device entirely.
