Shooting with both eyes open is a technique many strive for, offering a wider field of view and improved depth perception. However, for some, this seemingly simple act results in frustrating double vision, also known as diplopia. This can significantly hinder shooting accuracy and overall performance. Let's explore the reasons behind this issue and discuss practical strategies to overcome it.
Why Double Vision Occurs When Shooting With Both Eyes Open
Double vision when shooting with both eyes open arises from a lack of proper eye dominance and/or focusing mechanisms. Our brains are naturally wired to prioritize one eye's image, suppressing the input from the other to avoid seeing two separate images. When this suppression mechanism doesn't function correctly, or when both eyes are trying to focus on different points, double vision results. This can stem from several factors:
1. Lack of Established Eye Dominance:
Most people have a dominant eye—the eye their brain primarily relies on for visual tasks. If your eye dominance isn't clearly established, both eyes might compete for attention, leading to blurred or doubled vision.
2. Focusing Issues:
Proper focus is crucial. If one eye focuses on the target while the other focuses on a closer or further object (like the front sight or the background), you’ll experience double vision. This is common when trying to align the front sight, rear sight, and target simultaneously.
3. Eye Strain and Fatigue:
Prolonged shooting sessions can lead to eye strain and fatigue, making it harder for your eyes and brain to coordinate effectively. This can exacerbate double vision issues.
4. Underlying Eye Conditions:
In some cases, underlying eye conditions like strabismus (misaligned eyes), eye muscle imbalances, or refractive errors (nearsightedness, farsightedness, astigmatism) can contribute to double vision, even when not shooting.
Overcoming Double Vision While Shooting
Fortunately, various techniques and exercises can help you overcome double vision and shoot effectively with both eyes open:
1. Identify Your Dominant Eye:
Determining your dominant eye is the first step. Several simple tests can help you identify which eye is dominant. Once you know your dominant eye, you can focus on training your brain to prioritize that eye's image during shooting.
2. Focus Training Exercises:
Practicing focusing on different distances and objects can help improve your eye coordination and reduce double vision. Start with simple exercises like focusing on a distant object, then shifting your focus to a closer one, and gradually increase the difficulty.
3. Proper Shooting Technique:
Ensuring proper shooting technique is vital. Focus on proper sight alignment, ensuring both your front and rear sights are clearly in focus, and avoid unnecessary eye movements. A consistent and relaxed stance will also help reduce strain.
4. Patching Exercises:
While counterintuitive, temporarily patching your non-dominant eye during practice sessions can help strengthen your dominant eye's focus and improve your brain's ability to suppress the image from the other eye. Gradually reduce the patching time as your vision improves.
5. Professional Eye Examination:
If double vision persists despite trying these techniques, consult an ophthalmologist or optometrist. They can rule out any underlying eye conditions that may be contributing to the problem and recommend appropriate corrective measures.
Conclusion: Shooting With Both Eyes Open – A Skill Worth Developing
Shooting with both eyes open offers significant advantages, but overcoming double vision requires patience and practice. By understanding the underlying causes and employing the strategies outlined above, you can significantly improve your shooting accuracy and overall performance. Remember to prioritize proper technique, consistent practice, and seek professional advice if necessary. With dedication, you can master shooting with both eyes open and unlock a new level of precision.
