Topic on Talk:Sight
Could well be outdated information. The game itself should be considered the primary source of information, if you find something in-game that conflicts with the wiki, the wiki is wrong.
The little "i" button will have a lot of information. You can also look through the XML files supplied with the game. If you have a good text editor like notepad++, sublime or VS Code, you can use Find in Files to search through all references to Sight. If you can read English, you'll be able to make sense of what you find.
Certain values are hardcoded in C#, you'll need a decompiler to read those. That's a bit more difficult. Check the modding tutorials for links and information on how to use them.
