Adjusting the Lens Focal Length

Adjusting the Working Distance
Changing the working distance is a similar process.
A quick side note
Note that the working distance is tied to the focus of the camera lens. So if you change the working distance value, without adjusting the focus of the lens, then you probably won't see much of a difference. Basically behind the scenes, the working distance and lens focal length both contribute to the pixels across the eye measurement (also known as pixel density) for the image, and affect the size of pupils that can be found by the eye tracking algorithm.
To change the working distance setting in QuickACCESS, go to the
