A Bionic eye is an artificial eye that can replace a natural one through implant surgery. Unlike their natural counterparts, bionic eyes do not scar. They have 125% efficiency, increasing a colonist's sight by 12.5% for each one installed.
As with all bionics, it will give a mood buff to anyone with the Transhumanist trait and a heavy penalty to anyone with the Body purist trait.
Bionic eyes can be useful for gunners or snipers who will shoot enemies from a distance as a boost to sight can increase accuracy. Bionic eyes can also be used to "cure" cataracts in aged colonists.
In Beta 19 it received a nerf to efficiency but is now craftable.
