What Happens If Your PD Is Off on Your Glasses? Exploring the Consequences in 2023
Having an incorrect pupil distance (PD) measurement can negatively impact your vision when wearing glasses. The PD measurement determines the distance between your pupils, which is important for aligning the lenses properly with your eyes. When the PD is inaccurate, it can lead to blurred or distorted vision, eye strain and fatigue, headaches, dizziness or vertigo, and a limited field of view. Additionally, an inaccurate PD can affect the effectiveness of lens prescriptions in glasses. To ensure optimal vision and comfort, it’s crucial to have an accurate PD measurement taken by a qualified optician or eye care professional.
