Lens (Civ6)

Lenses are tools you can use to change your view of the world. Each lens will overlay important information that will help you make strategic decisions throughout the game. There are currently 11 different lenses in the game, 10 of which can be activated manually from the Lenses button above the mini-map, while the other one is activated automatically when you choose to place a or wonder from a city's Production menu.
== Automatic ==
The only automatic lens in the game right now is the District and Wonder placement lens. It is activated whenever you choose to place a or wonder from a city's Production menu. The lens will display the current territory of that city, valid spots for the desired or wonder that the city currently owns, and valid spots within the 3-hex workable range of the city that it doesn't yet own.
== Manual ==
In order to activate a manual lens, you need to turn them on from the Lenses button above the mini-map. There are currently 10 different manual lenses, only one of which can be activated at a time.
=== Appeal ===
The Appeal lens differentiates tiles based on their Appeal. The default hotkey for the Appeal lens is 3.
The color code means the following:
* Dark green tiles are Breathtaking, with an Appeal of 4 or higher.
* Light green tiles are Charming, with an Appeal of 2 or 3.
* Gray tiles are Average, with an Appeal of -1, 0, or 1.
* Orange tiles are Uninviting, with an Appeal of -3 or -2.
* Red tiles are Disgusting, with an Appeal of -4 or lower.
This lens is especially helpful when playing as a civilization or a leader who relies on high-Appeal tiles, such as the Mapuche, Teddy Roosevelt (Bull Moose), or Australia. It can also be used to great effect when checking how many tiles can benefit from Earth Goddess when picking a pantheon, or when choosing a suitable location for a National Park or a Seaside Resort.
=== Continent ===
The Continent lens shows the geographic extent of each continent. When turned on, each land tile will be color coded based on the continent it belongs to. The default hotkey for the Continent lens is 2.
This lens is useful when playing as a leader whose abilities make use of continents and their borders, and since continents are no longer synonymous with landmasses in Civilization VI, this lens becomes indispensable in those cases. These leaders are Teddy Roosevelt, Victoria, Philip II, and Dido. Each continent has also a unique set of luxury resources.
=== Government ===
The Government lens shows the distribution of governments across the map. When turned on, every tile that is owned by a major civilization will be color coded based on their current form of government. The default hotkey for the Government lens is 5.
This is not a very useful lens, since there is very little gameplay and few abilities that relate to the current forms government of two empires. Leaders with the hidden Ideologue agenda will like you a bit more if you have the same government but normally this is not much of your concern. Civilizations with different governments will receive a -25% penalty to towards one another, but it is rather unheard of to switch government forms just to avoid this penalty, since it is impossible to have the same government as everybody else in the game.
=== Political ===
The Political lens differentiates tiles based on their ownership. Each non-neutral tile will be colored based on the primary color of the jersey each civilization is using in that game. City-state tiles will be always in black and Free City tiles in dark gray. The default hotkey for the Political lens is 6.
This is not a very useful lens, since the the drawn borders on the map.
=== Religion ===
The Religion lens allows you to visualize the religious battleground of the game. The default hotkey for the Religion lens is 1.
Here you will see each city with its territory colored in the color of its majority religion; the territory of those without a majority religion remains blank. This is especially useful for theological combat, as is described elsewhere. Additionally, you will see colored circles emanating from each city that represent its Religious Pressure, and colored arrows pointing towards it from all nearby sources of Religious Pressure. The thicker the arrows, the stronger the pressure. Thus you can grasp at a glance what pressure is exercised where, and what you need to do to convert a particular city.
Under each city's name there is a special Religion tab, where all current religions are present which have converted Citizens. Clicking on the tab expands it and you can see more specific information: how many Citizens follow each religion.
Of course, you can also see additional information about Religion from the City Details tab.
=== Settler ===
The Settler lens highlights valid tiles for settling. Its additional function is to show the bonus for each tile, as well as Loyalty effects from nearby civilizations in Rise and Fall and potential disaster dangers in Gathering Storm. The default hotkey for the Settler lens is 4.
The color code means the following:
* Red tiles cannot be settled; either they are too close to other cities or their terrain doesn't allow settling.
* Dark green tiles have access to Fresh Water and will receive +3 if settled.
* Light green tiles are coastal and will receive +1 if settled.
* Gray tiles do not receive any bonus.
Furthermore, little icons on tiles mean the following:
* The negative Loyalty pressure from other civilizations is shown with number icons. Note that the actual negative loyalty pressure from citizens upon settling will appear to be slightly less as the pressure is partially counteracted by the city's Population upon founding, and in the Settler lens bonus Loyalty from happiness and other factors is not taken into account.
* Coastal tiles that may be flooded as the sea level rises are marked by a wave icon. There are 3 levels of coastal lowland tiles, which are also shown. (The tiles that belong to the first level which may be flooded by the first sea level rise are without numbers.)
* Floodplains tiles and tiles that are susceptible to volcanic eruptions are marked with their corresponding icons.
=== Tourism ===
The Tourism lens highlights which tiles in your empire are currently generating and how many tourists they have each attracted. If you hover above a tile that is generating , it will also show you the lifetime accumulation of of that tile. The default hotkey for the Tourism lens is 7.
The Tourism lens is the most useful when you have to decide where to assign the Governor with the Curator title (Reyna in Rise and Fall and Pingala in Gathering Storm) or just want an overview look of all the activities in your empire. 
=== Empire ===
The Empire lens shows your city borders, district locations with adjacency bonuses, and Wonders. You can also see inside other empires' territory, as long as you have direct vision over them, but you cannot see the adjacency bonus their s have. The default hotkey for the Empire lens is 9.
The Empire lens is the most useful when you are playing as a civilization or leader that relies on gaining high adjacency bonus on s by placing them next to one another, such as Germany (Hansa), Japan (all s), Mali (Suguba), or any focused civilization that wants to pull of a multiple-city Dam-Aqueduct-Industrial Zone formation.
=== Loyalty ===
The Loyalty lens helps you visualize all Loyalty pressure straight on the map. You will see arrows around each city which is experiencing Loyalty pressure, coming from the direction of the cities exerting the pressure. Each arrow's color matches the color of the civilization the city belongs to, and the thickness of the arrows represents the strength of the pressure coming from the relevant city - the thicker the arrow, the stronger the pressure. The default hotkey for the Loyalty lens is 8.
Additionally, under each city banner you will see a tab displaying the current Loyalty score: a bar in this tab will be filled with either green (which stands for "Loyal") or red ("Independence"). If the Loyalty score of the city is lower than 100 you will see both colors and you should start paying attention! Click on the tab to bring out a detailed breakdown of the different groups of factors affecting Loyalty - this will make it clear what influences the city negatively, causing its Loyalty to drop. Additionally, if a city is losing Loyalty, you will see a big red fist - the symbol of independence - flashing under it.
Of course, in the City Details tab you may see even more detailed information about current factors affecting Loyalty.
=== Power ===
The Power lens shows the distribution of in your empire. It differentiates between cities that are generating and the reach of their network, cities that are ed by another city, cities within range that don't require any , and cities that require but don't have any. The default hotkey for the Power lens is 0.
The Power lens gains most of its utility from the Industrial Era onwards, when you want to minimize the number of Power Plants you have to build to provide the most cities with .
== Search bar ==
The Search bar is a special type of lens used to highlight features of interest to the player. Only features present on a discovered tile (i.e., a tile not covered by the fog of war, but not necessarily in a unit's field of vision) will be highlighted. It was added in the Antarctic Late Summer Update as a Quality of Life change.
It is especially useful when you are searching for s or strategic resources that you just recent unlocked. This is the only way you can find s and strategic resources hidden under s. It can be also useful to check if any civilization is building (or already has built) a wonder or to look for unimproved tiles.
There are a couple of way to limit your search results. For example, if you just type "Coal" to the search bar to see if you own any in your territory, it is not the most useful that you will end up seeing all sources of belonging to your neighbors or sources half across the map that you cannot reach. You can limit these results by typing in the civilization you are playing (to limit the results down to sources of in your territory only) or the continent that you are interested in searching, such as "Japan Coal" or "Antarctica Coal".
You can also use the second input field to filter the results. For example, if you want to find Campuses that do not have a University, you can type "Campus" in the Search Terms and "University" in the Search Filter. You can easily find unimproved resources in a similar way.
== More Lenses mod ==
