Vision

"I can see! I CAN FIGHT!" -- King Arthur Liebowitz, Fairly Oddparents, "Knighty Knight"https://youtu.be/VFZcy6ls_DUVision is a sense. As the GURPS profile is human-standard, ordinary human vision (the visible light spectrum, average clarity) is a free (0 point) ability. Rolls using this sense are called vision rolls, and are a subtype of sense roll. Characters with poor vision will likely want glasses or contacts (or robust goggles!). Realistically, some humans may even have Acute Vision 1 or 2—ask a fighter pilot about it! 
== Uses ==
Vision can be used to determine if someone is cheating at a table gameBasic Set, p.197 or to tell if someone is following you.Basic Set, p.291 It's certainly the best sense for avoiding sharp debris in ruined areas, or caltrops left behind by dastardly villains.Low-Tech, p.123
Vision rolls often rely on the mark 1 eyeballunaided eyesight, but can be enhanced with all manner of optics and sensors, from telescopes to microscopes to Near Miss Indicators.TL9, Ultra-Tech, p.199 
== Other Notes ==
Digging creatures tend to have poor vision, while climbing and flying creatures, who rely on long-range senses, often have better vision.GURPS Space, p.164
== Limitations ==
=== Darkness ===
An extremely common penalty, one that's even a common phobia of many species.
=== Camouflage and Invisibility ===
Naturally, chameleon effects and camouflage are specifically good against vision, and detecting things that are well-hidden sometimes means needing another type of vision, or a really good sense of smell. Invisibility is a legendary boon for heroes, or a terrible danger from monsters.
=== Line of Sight and Cover ===
"Mr. Bradshaw, would you stand up please?" [Mr. Bradshaw stands up] [comical gunshot noise] -- "How Not To Be Seen" sketch, Monty PythonAny opaque object can block line of sight from normal vision (of course).
