In the intricate world of vision, each individual possesses a dominant eye that takes the lead in processing visual information. This dominance, often referred to as ocular dominance, plays a crucial role in activities that require depth perception, aiming, and focusing on specific objects. In this article, we will explore the concept of the dominant eye, its determination, and the impact it has on daily tasks and visual experiences. Ocular dominance refers to the preference of one eye over the other in receiving visual stimuli. The dominant eye takes the lead in transmitting signals to the brain, playing a central role in creating a unified and three-dimensional perception of the visual world. Understanding which eye is dominant is essential for optimizing visual performance and coordination [1,2].


Several methods can be employed to determine ocular dominance, and one of the most straightforward is the Miles test. Here’s a simple way to perform the Miles test. Extend your arms and create a small opening by overlapping your hands to form a triangle, with both thumbs and index fingers touching. Choose a distant object, such as a doorknob or a picture on the wall, and center it within the triangle created by your hands. Close one eye at a time while keeping the object within the triangle. The dominant eye is the one that keeps the object centered while the non-dominant eye is closed. Another method, known as the Porta test, involves extending your arm, creating a small opening by forming a circle with your thumb and index finger, and focusing on a distant object with both eyes open. Closing one eye at a time will reveal the dominant eye by noting which eye keeps the object centered. Ocular dominance plays a significant role in activities that require aiming, such as shooting sports or archery. Understanding the dominant eye helps individuals align their sights more accurately, enhancing precision in these activities. In sports like baseball or golf, where hand-eye coordination is crucial, knowing the dominant eye aids in positioning and aligning the body correctly. This knowledge contributes to improved performance and accuracy in various sports. Ocular dominance influences depth perception, affecting the ability to judge distances accurately. Individuals often rely on their dominant eye for tasks that require depth perception, such as driving or catching a moving object. While reading and writing are typically influenced by both eyes, understanding ocular dominance can be beneficial in determining the optimal reading distance and angle for an individual. It can also provide insights into potential issues such as eye strain during extended periods of reading. Identifying the dominant eye can contribute to overall visual comfort [3,4].


For example, when using optical devices like microscopes or binoculars, aligning the dominant eye with the device’s eyepiece can reduce eye strain and enhance the viewing experience. Understanding ocular dominance is crucial when prescribing eyeglasses or contact lenses. The prescription may be adjusted based on the dominant eye to optimize visual acuity and comfort. In cases where individuals opt for refractive surgeries like lasik, knowledge of the dominant eye helps surgeons tailor the procedure to address specific visual needs more effectively.
