Eye distance is the distance between a person’s two eyes, and normal eye distance is related to age, gender and other factors. Male, female and children eye distance are different, eye distance is calculated in millimeters, female eye distance is usually more 56-64mm, male eye distance is usually more 60-70mm, and children eye distance is usually around 55mm. Under normal circumstances, either too long or too short eye spacing, will make our face value looks greatly reduced, affecting the beauty of the face. Usually the eye spacing is wider for a girlish look and narrower for a more mature look, but either too wide or too narrow is not aesthetically pleasing. Whether a wide or narrow eye spacing looks good is related to the proportions of the patient’s face. It is recommended that patients with obvious abnormalities in eye spacing should seek medical attention to evaluate their condition and follow the doctor’s instructions.
