Archotech eye

The Archotech eye is an eye replacement which provides 150% sight efficiency. A superior version of the bionic eye.

Acquisition

Archotech eyes cannot be crafted. They can only be obtained through trade, as a reward from quests, from raiding ancient shrines, from security and hermetic crates, or at an extremely rare rate from random cargo pods^[Verify].

Summary

Archotech eyes replace natural eyes. Archotech eyes have a 150% efficiency, which results in a +50% improvement to Sight if two are installed.

However, the game places 75% weighting on the more capable eye for the purposes of sight. Installing the first archotech eye on a healthy pawn would increase sight by +38%, while the second would provide a +12% increase.

Installation

Installing the part requires 2,500 ticks (41.67 secs) of work, 2x medicine of herbal quality or better, and a Medical skill of 5.

Removing the part requires 2,000 ticks (33.33 secs) of work, 1x medicine of herbal quality or better, and has no Medical skill requirements.

If the operation fails even in a minor way the archotech eye will be destroyed.

Analysis

In a pawn with normal vision, installing a single archotech eye increases sight by +38%, and a second increases it by +12% to the expected 150%, since the game gives a greater weighting on the more capable part when calculating sight, with the best eye contributing 75% of a pawn's sight capability.

The Archotech eye can be very useful for combat, as sight enhanced above 100% greatly increases both melee and ranged accuracy. Cooking speed is also substantially improved. Sight above 100% also grants a bonus to melee dodge, medical tend quality, medical tend speed, and research speed. While most other skills are impacted by sight, the impact is capped at 100% sight, so the impact will only come into play if the colonist has their vision impaired for some reason. On the other hand, having sight above 100% can conceivably have some utility, even for skills capped at 100% as a form of reserve. For example, if a pawn has 120% sight, they could suffer a small wound to the eye, and still be performing skills as if they were uninjured, if the damage doesn't bring their sight below 100%. Under most circumstances, this would be a minor consideration, but could be useful in the very late end game when pawns don't have time to fully heal between raids.

A single archotech eye is enough to cap research and medical tend speed, and brings medical tend quality and melee dodge to very near their cap (138 / 140). Replacing the other eye with a bionic eye will hit these caps as well.
