Was the loss of the eye as a result of the wound written into the scenario? I don't claim to have read/played every scenario, but I do not recall any that specifically and permanently target a PC's eye.
Weapons with the “wound” critical hit effect have a random additional effect from rolling on a table (CRB page 182), one possibility of which is the loss of an eye if the target fails a saving throw.
For anyone finding this thread, Thursty has clarified that you don’t have to get a lost eye replaced and that you can get your eye replaced with a standard (no special abilities) prosthetic.
Official Clarification: Lost limbs or severed eyes count as a survivable condition between sessions, though the occurrence must be noted on the Chronicle Sheet of the scenario where the loss occurred.
Even More Official Errata: After speaking with the Starfinder team and its designer, we've decided that eyes can be included in the list of "limbs" replaceable by a standard prosthetic limb. Note: this only applies to a standard prosthetic limb and not to hideaway limbs or those with storage.
I suspect this will appear in a more official Starfinder Core Rulebook errata in the future, but for now, this ruling is official for Starfinder Society Organized Play.
