Sight is a property of units, structures, and certain summoner spells, items, and abilities in League of Legends that represents a team possessing vision of a target area. Inversely, the area of the map in which a team does not have sight over is known as the Fog of War, a common hallmark of the RTS genre which is represented visually as a dark shroud over the terrain.
Possessing sight is necessary to observe most information about any non-allied units in the game. Such information can include, among many other things, the unit's current location, direction, health, mana, possessed buffs and purchased items, making the acquisition and denial of sight one of the most crucially important skills to learn in high levels of play.
Sight Ranges
All units in the game will grant vision up to a specific radius:
- 1350:
champions, pets, super minions, and turrets - 1200: melee, caster, and siege minions
- 900: Totem Wards, Stealth Wards, Control Wards, Zombie Wards, and Effigies
- 500: Farsight Wards
- 450: Ghost Poros
- Disabled wards do not grant vision.
- Items and abilities do not always grant sight and those that do often have differing applications of the mechanic to one another.
Blocking sight
There are two obstacles that exist towards regular sight - impassable terrain (which is always opaque to vision granted by units, structures and most items and abilities) and 
Brush (which is opaque towards vision when viewed from the outside inwards and not the reverse). Such barriers will also block vision of any areas that are directly behind them from the sight-granting unit. Units that can directly observe an area around these obstacles are commonly described as having line of sight towards that area.
Sight can be removed in three ways - the withdrawal of any sight-granting units, abilities or items from the vicinity, the expiration of a sight-granting debuff or spell, or directly with the 
nearsight debuff (which currently only exists with 
Graves' 
Smoke Screen, 
Nocturne's 
Paranoia, and Quinn's 
Blinding Assault). Be noted, however, that despite looking like such, 
Rek'Sai's 
Burrow does not necessarily nearsight her, as she conserves allied vision.
Forms of sight
True sight
A unit 
revealing a 
stealthed trap. A pink eye symbol above a unit indicates they have true sight vision.
This is a unique form of sight that is able to see units concealed in 
stealth, who are usually undetectable when under standard sight (such as 
wards and standard sight debuffs). All sources of true sight currently in the game also provide standard sight - otherwise, true sight follows the same rules as standard sight. True sight cannot bypass sight blocked by nearsight. All 
turrets and some abilities and items and a few others possess a form of true sight, mostly by revealing debuffs.
Obscured vision
A silhouette of a unit observed behind a wall, indicating a form of 
obscured vision.
This is a form of detection that does not innately reveal units nor make them targetable in any sort of way. Instead, the unit's position is merely distinguished by their movement and actions or silhouette, revealing their position in the process. The unit is still not visible however, thus being unable to selected for 
unit-targeted attacks. Obscured vision exists in many effects, the most common ones being in Rek'Sai's Burrow and 
Oracle Lens. It is unaffected by nearsight.
Unobstructed vision
A unit with 
unobstructed vision being able to see enemies behind walls.
This is a type of sight that permeates through terrain. It allows the unit to be able to see beyond their sight radius if otherwise obstructed by terrain, although they won't be able to see into brush unless they had sight of the inside. 
Aurelion Sol's 
Comet of Legend, 
Kayn's 
Shadow Step, 
Talon's 
Assassin's Path, and 
Zoe's 
Portal Jump are the only abilities that benefit from unobstructed vision.
A unit with unobstructed vision becoming unable to see out of terrain while nearsighted.
Nearsight prevents unobstructed vision entirely; units lose the ability to see behind walls for the duration and if they would be inside terrain, their sight is completely restricted until they move out to open space.
The objects listed below are abilities and items that can temporarily grant sight of an area or enemy, as well as which of those abilities and items grant true sight.

Standard Sight
Area-reveal
By default, when attacking an enemy (including wards) from their team's Fog of War, it will reveal a 450-radius area centered on top of the attacker for 4.5 seconds when their attack completes.
