Morphology
The meaning is directly derivable from 'cross' (intersecting lines) + 'hair' (a very thin filament), i.e. very thin intersecting lines used for aiming. The metaphorical use of 'hair' to mean a fine line is common and the compound follows a transparent descriptive composition that a B1 learner who knows both words can readily interpret.
Etymology
Cross hair comes from old sights that used very thin hairs or lines that cross each other to make a small mark to aim at. That's why a cross hair is the fine lines in a scope or microscope used to 'aim' or 'measure' exactly.
