[Quick Tip] Glasses and Eye Gaze

Glasses and eye gaze technology don’t always play nicely. It can be tricky for a camera to pick up the users’ eyes and accurately track their movement if they have a certain type of glasses prescription or have had eye surgery in the past. If at first the eye gaze camera doesn’t succeed – don’t give up! It can be a quick fix at the optometrist to be able to utilize this technology.

Types of Glasses

Certain types of glasses can affect the accuracy of the eye gaze camera. Based on experience with our users, it’s best to stay away from bifocals or progressive lenses. If possible, talk to your optometrist to see if there are other lenses options for you. Metal frames can also affect the accuracy of the camera, so avoid those if possible.

Types of Coatings

Some coatings on lenses will block the eye gaze tracker from detecting eye movement, so it’s best to avoid NIR blocking coatings or glass material. Speak with your optometrist to see if you can remove or abstain from these coatings when you get your prescription.

Best Practices

Some other best practices for glasses-wearers are making sure the glasses are clean and smudge-free. Tilt your head up and down to identify and avoid any light reflections from the camera.

We use the Hiru eye gaze camera with our devices, and they provide some tips and tricks in the video below for users who wear glasses. Check it out:
