Why is Pupillary Distance (PD) Important for Prescription Glasses? Pupillary Distance (PD) is crucial for prescription glasses because it ensures that lenses are positioned correctly in relation to the eyes. Proper alignment enhances visual comfort and clarity. When lenses are centered over the pupils, they help reduce eye strain and improve the effectiveness of the prescription.According to the American Optometric Association (AOA), pupillary distance is defined as the distance between the centers of the pupils of the eyes. Accurate PD measurements are essential for achieving optimal vision through corrective lenses. The importance of PD stems primarily from how our eyes perceive images. When lenses are not aligned with the pupils, it can cause visual distortions. Misalignment may lead to symptoms such as headaches, double vision, or general discomfort. Proper PD support helps maintain the optical center of each lens directly in front of the pupil, ensuring that light is directed correctly through the lenses.Technical terms relate to how glasses work to correct vision. “Optical center” refers to the central point of each lens where light passes through with minimal distortion. If the optical centers do not align with the pupils, the wearer might experience blurriness or visual fatigue.The mechanism behind PD’s significance involves how light interacts with the lenses. Light enters the lens and is refracted, or bent, to focus on the retina at the back of the eye. If PD is inaccurate, it affects how the light is focused. This can result in images that are not clear or well-defined, leading to eye strain and discomfort.Certain factors contribute to inaccurate PD. ‎Take accurate Pupillary Distance (PD) measurements using your iPhone's TrueDepth Camera system.
