Eye detection

I'm playing around with the object detection and it detects eyes fairly decently. For a project I'm working on, I need to be able to detect if a users eyes are closed. I figured that the eye script would detect only open eyes, but apparently I tried it with a specific image and it still registers closed eyes. Is there a way to detect specifically if an eye is closed or to reduce the sensitivity of the detection script?Moreover, I'm fine with getting users to cover their eyes or some other method, just curious what the outlook is for the eye script.

Start with the eye detection script and the existing object-detection behavior described in the issue. Determine whether closed-eye detection or a sensitivity control is supported, then define a concrete approach and verify it against images with open and closed eyes; the issue is done only when one of those behaviors is implemented or clearly documented.
