Does Eye Control AF present any eye heath risk?

I received my R3 at the end of December and have really enjoyed using the camera.  I am intrigued with Eye Control AF, but have not enabled the feature.  I am legally blind (0 left - 20/200 right) and have concerns there might be eye health risks using Eye Control for extended periods. Needless to say, I am very protective of the vision I have and can't afford any detonation.  Has anyone read material on the technology used to track the eye and potential risks associated with the technology.  I know IR can have a detrimental impact on the eye, but not sure if that varies based on the wavelength and intensity.  Once I have a subject in the VF, I tend to stay locked on the image rather than have to hunt for the subject (wildlife).  This would be a very helpful feature for me.

Interested in any thoughts or information.

David
