what happens if your pd is off on your glasses
How does having an incorrect pupil distance (PD) affect your vision with glasses?
Having an incorrect pupil distance (PD) measurement can have a significant impact on your vision when wearing glasses. The PD measurement determines the distance between your pupils, which is crucial for ensuring that the optical centers of the lenses align properly with your eyes. When the PD is inaccurate, it can lead to various visual problems and discomfort.
One common issue that arises from an incorrect PD is blurred or distorted vision. If the lenses are not aligned correctly with your pupils, they may not be providing optimal clarity. This can result in objects appearing blurry or out of focus, making it difficult to see clearly. Additionally, an inaccurate PD can cause eye strain and fatigue as your eyes work harder to compensate for the misalignment.
Consequences of wearing glasses with an inaccurate PD:
- Blurred or distorted vision
- Eyestrain and fatigue
- Headaches
- Dizziness or vertigo
