Sight

Sight affects most colonist stats, with varying impact, though its importance will depend on the pawn's role in the colony. Sight is capped at 100% for many stats, but some combat and medical skills are uncapped. 
, the maximum possible Sight capacity in the core game is 250% with a healthy pawn high on go-juice and luciferium with two archotech eyes installed, while also being infected with sensory mechanites. With the Royalty DLC installed, it is possible to reach a Sight capacity of up to a maximum of 325% with the addition of the Focus psycast.
== Effects ==
Sight has a number of unique interactions with other mechanics, beyond the traditional effects on stats. 
At Sight 0% provides +50% psychic sensitivity. As of version 1.5, Blindfold which reduces Sight to 20% or other forms of non-total blindness no longer provides psychic sensitivity bonus.
Pawns with 0% Sight:
* Are not subject to the factor from low light levels on move speed or on global work speed. 
* Will not receive the "Observed corpse" or "Witnessed ally's death" moodlets.
* Do not gain nor lose any opinion for any other pawn based on their beauty stat.
* Do not lose any opinion for disfigured pawns.
* Cannot recreate at a telescope, poker table, billiards table, hoopstone ring, books or any type of television. They also cannot skygaze or view art for recreational purposes.
* Gain +30% psychic sensitivity if they also have the Blinded with blind psysense precept and both their eyes removed. This stacks with the aforementioned bonus for 0% sight bonus.

== Formula ==
The formula for sight is:
Sight = (Base efficiency + Offsets) × Post factors
Base efficiency is the result of combining both eyes efficiencies, with a 75% weight to the strongest eye. There are many way of writing it, but for this section the following will be used:
Base efficiency = (right eye + left eye)/4 + max(right eye, left eye)/2
Offsets are additive with each other.
All factors that affect Sight will be listed below.
=== Base efficiency ===
* Eye efficiency. 100% importance, no allowed defect, no max.
** The game assigns 75% weight to the stronger eye and 25% weight to the weaker, so entirely losing a single eye reduces sight by 25% rather than 50%.
** Blindness: 0% part efficiency
** Cataract: 50% part efficiency. Results in sight for the first eye affected, for the second eye.
** Bionic eye: 125% part efficiency. Results in sight for the first one installed, for the second one.
** Archotech eye: 150% part efficiency. Results in sight for the first one installed, for the second one.

=== Offsets ===
The following offsets affect Sight.
* Sensory mechanites: 
* Go-juice: 
* Luciferium: 
* Tox gas:
** Mild: 
** Moderate: 
** Severe: 
=== Post factors ===
* Blindfold: Sets maximum to 20%
* Focus psycast : x130%
== Example == 
If we were to calculate the highest possible value in unmmoded rimworld, we would have:
*Base efficiency: 
** Right eye: 150% (archotech eye)
** Left eye: 150% (archotech eye)
*Offsets (total ):
** Luciferium: 
** Go-juice High: 
** Sensory mechanites: 
*Post factors:
** Focus psycast: x130%
From this, Base efficiency would be:
Base efficiency = (1.5 + 1.5)/4 + max(1.5, 1.5)/2 = 3.0/4 + 1.5/2 = 0.75 + 0.75 = 1.5 = 150% 
Replacing values, the maximin Sight capacity is:
Sight = (1.5 + 1.0) * 1.3 = 3.25
Sight = 325%
