“You are a creature of the night! Though this doesn't allow you to spend Perk Points on perks you don't have the Intelligence or Perception to unlock, you do receive the impressive enhancements that a higher INT and PER allow you. For example, you have a greater distance to spot enemies and V.A.T.S. enhancements for Perception and the increase in XP that an Intelligence boost gives you.”— Fallout 4 Vault Dweller's Survival Guide description

The night vision will always be active when sneaking indoors, regardless of the time of day. This is generally helpful but may get too bright in well lit rooms.
The night vision bonus may remain active while standing / during daylight hours (6:00 A.M and 6:00 P.M.). This causes the sides of the screen to be blurred when standing, and can cause things to be WAY too bright during daylight hours/indoors. Fixes (works on console too):
- Fix 1: While standing, go into the Pip-Boy, then into the skill tree, then back back out (sometimes just going into the Pip-Boy and backing out works).
- Fix 2: While Standing, go to any container and enter the 'transfer' screen, then back out.
- Force Bug to Happen: The bug may be manually activated by crouching, waiting for night vision to activate, then going into the Pip-Boy, backing out, and standing up.[verified]
