square prescription glasses

square prescription glasses

Square glasses have been steadily riding the wave of popularity over the past decade, and at this point, it’s safe to assume that they’re here to stay. In fact, with a quick look around, it becomes pretty clear that square frame glasses are trending more now than they ever have. You’ll find big square glasses, smaller frames, and just about any type of square frame in between. If you’re looking for trendy glasses frames, squares are a universally flattering choice that you can find in a broad range of colors, sizes, and patterns. You can even find prescription sunglasses with square frames! Of course, like with all frame shapes, square eyeglass frames do work better with some face shapes than they do with others, which we touch on below. Read on to learn more.

Check size on your frame

Most frames have size displayed on the inside of the frame arm

Or use a ruler

Use a ruler to measure your existing frame as shown below. Frame sizes are measured in millimeters, so you need to use a ruler that is marked in centimeters and millimeters. If you don't have millimeter ruler, you can click here to print it, or take measurements in inches. Note that measurements in inches need to be taken with the precision of 1/16 (one half of 1/8 if your ruler does not have more precise markings)

Measure your PD

In some cases your vision correction doctor may forget to give you your PD (pupillary distance). The best option will be to ask your doctor to measure it. It is part of your prescription and an eye doctor needs to provide it.

If this is not possible, you may use the methods listed below.

The easiest way:
1) Wear any glasses with clear lenses.
2) Use a mirror or ask a friend or family member to mark your pupil location on the clear lenses using a dry erase marker. They must stand in front of you and be at the same height as yours. If you use a mirror make sure you stand 3ft from the mirror and your general stare is directed to the center of the glasses.
3) Using a ruler with a millimeter range, measure the distance between the two dots and that’s your PD

If you don’t have in your possession glasses with clear lenses, you may measure your PD using this method:
1) Obtain a ruler with millimeter values
2) Place the ruler horizontally on your nose bridge, zero slightly below your right eye;
3) Ask a friend or use your mirror to see the distance on the roller. The distance measured is your PD.

Although we don’t recommend this option, if you are unable to use the methods above, you may use the general PD for: Women 62 and Men 64.
