The Traditional Dominant Eye Test is Failing You as an Instructor

Ego Center Visual Error

An ego-centric visual error, also known as an egocentric visual localization error, is a type of perceptual illusion where a person’s sense of their own position relative to visual targets in space is consistently and incorrectly shifted. This can lead to a distorted perception of where objects are in relation to oneself.

The concept of “ego center” in shooting, particularly as it relates to accuracy, is a fascinating and often misunderstood topic that goes beyond the simple “dominant eye” test. While the dominant eye is a critical factor, understanding the ego center can unlock a higher level of shooting performance, especially in dynamic situations.

What is the Ego Center?

In the context of human vision, the “ego center” is the perceived origin of visual direction. Think of it as the central point from which all visual lines of sight radiate. In normal binocular (two-eyed) vision, the ego center is located on the median plane of the head, typically at the bridge of the nose, roughly halfway between your two eyes.

When you’re looking at an object, your brain processes the input from both eyes and synthesizes a single, unified image. The ego center is the brain’s internal reference point for where “straight ahead” is.

The Problem – Ego Center at the Bridge of the Nose or at the Inside of the Eye at the Nose

For many shooters, the ego center being at the bridge of the nose works perfectly fine when they are stationary and taking a very deliberate shot, such as in slow-fire target practice.

However, the problem arises in dynamic shooting or when shooting with both eyes open. If the ego center remains at the bridge of the nose, the shooter’s brain will try to align the firearm with this central point, not with the dominant eye.

Here’s why that’s an issue

• Misalignment: The sights of the gun are aligned with your dominant eye, not the center of your face. If your brain is telling you to aim from the center of your nose, your shots will naturally be misaligned to the side of your dominant eye. For a right-handed shooter with a dominant right eye, this could mean shots consistently impacting slightly to the left.
• Instinctive Shooting: In fast, instinctive shooting (e.g., in a self-defense situation or dynamic competition), the shooter may not have time to consciously align the sights with their dominant eye. They will instinctively point the firearm where their ego center tells them to, which will be off-target.

This is particularly noticeable in situations where the shooter is tracking a moving target, like in shotgun sports (trap, skeet, sporting clays). If the ego center is in the middle of the face, the muzzle of the gun will have a tendency to want to line up between the ego center (bridge of the nose) and the target, leading to a consistent miss.

The Solution: Shifting the Ego Center to the Dominant Eye

Top-tier shooters, especially in sports like shotgunning or combat pistol shooting, strive to “stabilize” their ego center to their dominant eye. This is not something you can consciously do by simply thinking about it; it’s a learned skill that involves training your brain to change its default visual reference point.

By training the ego center to be at the dominant eye, the shooter achieves a critical advantage:

• Natural Alignment: When the ego center is aligned with the dominant eye, the natural, “instinctive” pointing of the firearm will be perfectly aligned with the sight picture. The gun becomes a natural extension of the eye, not the face.
• Faster Target Acquisition: The shooter no longer has to make a conscious mental correction to align the sights with their dominant eye. The brain is already using the correct visual axis. This leads to faster, more accurate shots, especially on moving targets.
• Overcoming Cross-Dominance: For shooters who are cross-dominant (e.g., right-handed with a dominant left eye), training the ego center to the dominant eye is the key to unlocking their full potential. Without this correction, they are constantly fighting their own brain’s instinctive alignment. However, it’s crucial to approach this carefully and avoid attempting to force a switch in eye dominance itself. Research by Larry Yatch of Sealed Mindset and Mike Ox highlights significant risks in trying to override natural eye dominance. Their studies, involving observations from competitions, use-of-force scenarios, and force-on-force training, show that apparent successes in switching dominance often fail under high stress. The brain tends to revert to its natural dominant eye, as the image from the dominant eye is processed at least 14ms faster than from the non-dominant one. Forcing a dominance change can create perceptual distortions in time, distance, and direction, sometimes leading to vocal stuttering (e.g., hesitations in speech) or physical stuttering (e.g., motor hesitations or inaccuracies). Additionally, Mike Ox has noted that the U.S. Air Force (USAF) has conducted extensive work in recent years on switching eye dominance for pilots using helmets with embedded displays. Despite their efforts to force adaptation, there is a notable neurological cost to the pilots, including increased cognitive load and potential long-term strain. Instead of pushing for dominance switches, instructors should focus on adaptive techniques that work with the shooter’s natural dominance, such as adjusting stance, grip, or using occlusion methods temporarily during training to build ego center alignment without attempting permanent neurological rewiring.

How to Train for this Shift

The shift in ego center is typically not a conscious effort but a result of consistent, purposeful training. Here are some of the concepts involved in this training:

• Sustained Focus on the Target: This is a core principle in many shooting disciplines. By keeping your visual focus locked on the target, you allow your brain to process the sights in your peripheral vision. This helps the brain learn to prioritize the visual input from your dominant eye, which is the one that is correctly aligned with the sights.
• Visual Drills: Some instructors use specific visual drills to help “lock in” the dominant eye. This can involve exercises that force the shooter to be more aware of their non-dominant eye’s visual input and suppress it, or to deliberately focus on the target in a way that forces the brain to use the dominant eye as the primary point of reference. Importantly, these drills should emphasize working with natural dominance rather than against it, drawing on insights from experts like Larry Yatch and Mike Ox to avoid the pitfalls of forced switching.
• Repetition and Consistency: Ultimately, like any other motor skill, training the ego center is about building new neural pathways. By consistently practicing proper form and technique, with a focus on target acquisition through the dominant eye, the brain will gradually shift its internal ego center to that eye, making accurate, instinctive shooting a reality.

The concept of the ego center is a high-level one in the world of shooting, often discussed by elite coaches and trainers. While most shooters can get by just fine with a basic understanding of eye dominance, understanding and training to shift your ego center can be the key to breaking through a performance plateau and achieving a level of shooting accuracy and speed you didn’t think was possible.

The journey to mastering the ego center in shooting is a testament to the power of targeted training and neural adaptation, offering shooters a pathway to unlock their full potential. For those eager to dive deeper into this transformative approach, much credit is due to Mike Ox, a renowned firearms instructor and author who has extensively explored and taught these concepts through his work, as well as Larry Yatch of Sealed Mindset for their collaborative research on the limitations and risks of eye dominance switching. Their insights, drawn from years of experience, practical observations, and writings—including resources available at visiontraining.com—provide invaluable guidance for instructors and shooters alike looking to refine their skills and overcome perceptual barriers while respecting neurological realities.
