Despite the Cloud being a highly deadly substance, it is perfectly safe to consume with no side effects. Ghost Sight is vastly more abundant than any of the other low-light vision consumables, especially since they also require very little to craft. They are extremely easy to acquire, even after completion of the Dead Money add-on.
Ghost sight must be crafted by the player as it cannot be found on enemies or in containers.
- Using Ghost Sight and Cateye simultaneously results in an even brighter "cyanotype" vision. Nuka-Cola Quartz can also be applied in combination with the two, but this alters the effect to an excessive degree.
