Yes, glasses or contact lenses are not a handicap when using eye trackers. However, you should be aware of a few points:

  • The lighting conditions in your environment should not produce any reflections on your glasses that would make your pupil unrecognizable to the eye tracker
  • Glasses with a small frame could obscure the pupil from the eye tracker during head movements
  • Bifocal glasses may confuse the eye tracker in a few cases
