Blindness or Impaired Vision
Source GM Core pg. 22
A blind character can't detect anything using vision, critically fails Perception checks requiring sight, is immune to visual effects, and can't be blinded or dazzled. You might give this character the Blind-Fight feat for free.
A character with impaired vision might take a –2 to –4 penalty to vision-based Perception checks. Spectacles or other corrective devices and augmentations might reduce or remove this. Such devices are commonplace and accessible throughout the universe and can be found in most settlements or created on demand at UPB printing kiosks. They usually cost 5 credits and are available in a variety of forms. If the device is an augmentation, it doesn't count toward a character's implant limit. Likewise, if it's an armor upgrade, it doesn't occupy an upgrade slot.
