Ahh. Yeah, I'd allow it. Not sure why you'd want to sneak your datajack in your eye though. 0.1 Essence is about as Essence-friendly as things get, and datajacks are not just legal but encouraged in most places.
Actually this is an old school trick out of SR2 Cybertechnology pg 20. It is handy when you don't want an obvious datajack visible, perhaps to keep a certain cover intact.
There actually was two styles:
one where you tapped the iris to open it and reveal the standard datajack.
The second system was kind of neat, an optical scanning datajack. A two part system, you had a small battery sized emitter that plugged into any data-out port on the system and it sent out the data in a low power laser beam that you looked at with the optical eye and it translated the data.
While I imagine wireless pretty much made the latter obsolete, it might still have some uses for devious minds.
