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. Externally, it looks like a natural human eye, except it can change color at will. Its internal workings are a mystery to all human minds.
Since the game gives a greater weighting on the more capable part when calculating sight, with it contributing to 75% of a pawn's sight capability, installing a single archotech eye increases sight by 38%, and a second increases it by 12% to the expected 150%.
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). Adding a second, bionic eye will hit these caps as well.
