Archotech eye

Archotech eye

An artificial eye built by an archotech. It perceives every type of electromagnetic radiation, including radio waves, infrared, light, x-rays, and gamma rays. Its visual acuity is precise enough to read handwriting from twenty meters away. It can emit various wavelengths of radiation like a flashlight, and has an internal subpersona AI which helps highlight useful visual information. Its internal workings are a mystery to all human minds.

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


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 cratesContent added by the Ideology DLC, or at an extremely rare rate from random drop pod crashing.


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.


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.


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 it greatly increases both melee and ranged accuracy. Cooking speed is also substantially improved. Vision 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, they have 100% sight caps and will only see an effect if the colonist has their vision impaired for some reason.

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.
