How to measure an eyeglasses frame?

To measure glasses frames, follow these steps:

What is PD?

PD stands for Pupillary Distance, which is the distance between the centers of your pupils. This measurement is crucial for ensuring proper alignment of the lenses with your eyes. 

To measure PD, you can use a ruler or a specialized PD ruler. 

Quick takeaways of PD measurement:

1.Stand in front of a mirror and hold the ruler against your forehead, aligning it with your eyes.

2.Close your right eye and align the ruler's zero mark with the center of your left pupil.

3.Look straight ahead and close your left eye while opening your right eye.

4.Read the measurement on the ruler aligned with the center of your right pupil. This number is your PD.

Eyeglasses frame measurement

1.Frame Width: Measure the width of the entire eyeglass frame, from the outer edge of one temple arm to the outer edge of the other arm. Use a ruler or a tape measure to get an accurate measurement.

2.Lens Height: Measure the vertical height of the lens, including any part of the frame that holds the lens. Measure from the top to the bottom of the lens, excluding the frame arms.

3.Lens Width: Measure the horizontal width of each lens separately. Measure from the outer edge of one side of the lens to the outer edge of the other side.

4.Bridge Width: The bridge width is the distance between the two lenses where they rest on your nose. Measure the smallest part of the bridge, which is typically located between the lenses.

5.Temple Length: Measure the length of the temple arms, which are the parts that extend from the frame to the back of your ears. Measure from the frame's hinge to the end of the temple arm.

It's worth noting that these measurements can vary slightly between different eyeglass frame styles and brands. 

If you're unsure about any specific measurements or need precise measurements for ordering prescription glasses, it's recommended to consult with an optician or eyewear professional who can assist you in getting accurate measurements.
