A player recently got the idea that obvious cybereyes should be cheaper, just like obvious cyberlimbs.
I disagreed, but for the sake of group morale I'm asking here. If possible, I would like a rule-as-written, but I accept also good reasoning.
His vision how his eyes will look like: Picture converted to jpg from Wikipedia
In my opinion the technology in Shadowrun 5 is far enough to produce a life-like eye if requested. Upon close examination the eye will of course be detectable as a artificial object, but in general daily contact the difference should not be visible.
Of course any character can decide to drastically alter the appearance of the eyes (to a certain degree), for example full-black, rainbow or a slightly altered form. This is the characters decision however and not a "fault" in the cybereye (IMO).
