Frequently Asked Questions

What is the easiest way to find your dominant eye?

The easiest way is the Miles Test: form a triangle with your hands, focus on a distant object through it, and bring your hands to your face. The eye that keeps the object centered is dominant. Alternatively, use the Porta Test by pointing your finger at an object and seeing which eye stays aligned when closed.

Why is knowing your dominant eye important for shooting?

Your firearm naturally aligns with your dominant eye. Knowing which eye is dominant ensures proper sight alignment and helps prevent inaccuracies caused by trying to compensate for the non-dominant eye, which may have weaker vision.

Can eye dominance change?

Yes, eye dominance isn't always fixed. Factors like lighting conditions, the distance to the target, and even the tactile feedback from holding a firearm can influence which eye the brain favors for aiming.

What are the benefits of shooting with both eyes open?

Shooting with both eyes open significantly improves situational awareness and peripheral vision. It requires training your brain to prioritize the visual input from your dominant eye while still incorporating information from the non-dominant eye.
