We don't know that he was lessened, and it may not have been requested or required. He might have just felt guilty about it. All I'm saying is that it's rather suggestive that he has them shortly after the loss of the D. It suggests a bit of story, given his visor was used against them in that situation, & he knew he could prevent itYet why would Data's best friend agree to being surgically weakened when Data himself, the greatest menace to Starfleet after Jean-Locutus Picard, has never volunteered to lobotomy?
Everybody in the main cast has been compromised in his or her turn. Starfleet's only hope is finding ways to cope with the fact that its personnel will be co-opted, and those ways shouldn't include firing or mutilating said personnel.
but what I'm saying is that may only be 1 setting that he frequents the most. There's nothing said about him not having the same capabilities as he had with the visor. In the absence of evidence against it, I choose to assume he has the coolest eyes I can imagine, which includes multitudes of different settings "Predator 2" style lolFrom our literal insight into the new device in ST:INS, as contrasted to our literal insight into the VISOR. The contacts just have the zoom, plus some easily comprehensible HUD-style data; if the audience can comprehend it, then it must be less extensive and complex than what the VISOR had to offer.
I'll admit that is odd, since we see his eyes work with the normal vision/zoom thing, which does look normal to me at least. So, I have to assume it still doesn't deliver the "Human" experience as well as real eyesWhich of course is false, because only when the contacts come off does LaForge admit to seeing a sunset like humans do.
