What is eye dominance and how does it affect aiming?

• A. Eye dominance has no impact on aiming.
• B. You should rely on peripheral vision only.
• C. The dominant eye usually guides aiming; align sights with your dominant eye for accuracy.
• D. You should close your dominant eye when aiming.

Answer: (C)

Eye dominance is the tendency to rely on one eye more than the other for precise vision. When you aim, the line of sight from your dominant eye becomes the reference you use to align the sights with the target. Because that eye provides the strongest, most stable signal, keeping the front sight aligned with your dominant eye gives you a consistent and accurate point of aim. You can keep both eyes open to preserve depth perception, but closing the dominant eye removes that anchoring and typically makes aiming less accurate. If you’re not sure which eye is dominant, you can test it with a simple sighting activity, but the key idea is to use the dominant eye as the reference for alignment. So, align the sights with your dominant eye for better accuracy.
