How to unlock the Clear Headed achievement in Thief - Definitive Guide
Or if you just turn on "No Focus" in the custom difficulty screen when you're starting a new game. This setting literally disables focus so that it cannot be used, so you'll get this achievement if you can just finish the game with this setting on.
If you are playing without this setting enabled and accidentally use focus, you should be able to reload your checkpoint as long as it's before your focus use. That's according to reports, I cannot personally verify that.

Focus ability (activated via ), grants you the ability to survey your surroundings for thieving opportunities. While in focus and briefly after deactivating focus, objects that you can interact will glow in blue, such as rope arrow-able beams and loot you can pilfer, and so forth. Therefore, focus mode serves as a fundamental ability in progressing through this game as it shows you possible routes that you can take when completing a level.
However, for the purpose of this trophy, you will not be able to use the focus ability at all until the final chapter to unlock it. That said, it is recommended you do this on your Master Custom second playthrough of the game, as one of the handicaps we suggest is having the "No focus" into play. This will also remove the possibility of you activating focus by accident, forcing you to replay the game once again for the trophy.
