How to Choose Eyeglasses
We include the size measurements on the product details pages for each frame. If you have current eyeglasses already, nearly every pair of prescription glasses has sizing numbers written on the inside of the arms or on the bridge or on the back of the bridge.
The measurement is generally written like this: 53-17-142. The first measurement is lens width, the second is the bridge width, and the third is the temple length.

How to Measure PD?
What is PD
Your pupillary distance (PD) is the distance in millimeters between the centers of your pupils. In order for our glasses to perform at their best,we use this measurement to align the optical center of the lens with the center of your eye. Unfortunately, many opticians don’t include your PD in the prescription. However, you can ask your optician for it directly during your eye exam. Then you will be able to get lenses at any store you choose.
Average PD is about 62mm and most people fall within the 54 to 74 range. Sometimes your eye doctor will write your pupil distance for each eye (for example 34/35, called a monocular pupil distance). Or, the eye doctor may write the pupillary distance measurement as 69/65. This means that your pupil distance for distance vision (or DPD) is 69, and for near vision (or NPD, for reading eyeglasses) is 65.
How to Measure PD
While an optometrist’s PD value is always recommended,your Pupillary Distance (PD) is something you can measure by yourself or with the help of a friend. If you chose to measure your own PD, please do so in millimeters.
To measure your Pupillary Distance (PD):
- Place a millimeter ruler on the bridge of your nose.
- Line up the starting point (0 mm) with your left (or right) pupil (the black dots in the middle of your eyes). This measurement is only accurate if you are looking straight ahead.
- Looking straight into the mirror, hold the ruler (keeping it steady and parallel to the floor) and mark the location on the ruler of the other eye’s pupil. Or if someone else is reading the ruler they must be at the same height as you and be sure to hold the ruler steady and parallel to the floor.
- Measure the distance in millimeters between the two marks. This is your PD
- Repeat the process two or three times for accuracy.
- Record your results.
Do not try to measure anything on your current glasses, as there is no way to measure your PD from them. Please do not guess or assume your PD.
