How to find your sunglass model?

Find Your Model Number

look on your inside arms for your model and size information to get correct sunglass replacement lenses

When using our search to locate your model, putting in less information is generally better than more. We store lens information by model, usually the four numbers or name of your frame will do. We don't keep a record of all the subsequent numbers that manufacturers use.

For example a Ray Ban frame will have RB#### on the left arm. Simply type the #### numbers in our lens search engine and it will usually display a few models along with their photos.

Double checking the lens width measurement is very important. You’ll find this on the inside of the arm (usually written before a small square) or simply measure your sunglasses as instructed below to make sure you get the right lenses for your frames.

Many brands such as Persol, Prada, and Ray Ban Sunglasses commonly use the same model number but make several different sizes. For example, the Ray Ban Aviator Large Metal sunglasses all have the model number of RB3025LM. However, they come in 3 sizes - 55mm, 58mm and 62mm wide.


Manually Measure Your Lens Size

lenses are measured at maximum width in millimeters as the crow flies parallel to ground

You should measure a lens at its widest point - as the crow flies. However, with only two to three millimeters difference it can be hard. Most sunglasses have writing on the arms or under the nose bridge providing this information. If you have your original packaging you could also find it there. We strongly recommend checking your frames to avoid disappointment by getting the wrong size lens.

The Industry Standard (and The Sunglass Fix) measure lenses at the maximum width as the crow flies. Not along the curve of the lenses. It’s worth noting that lenses are almost always measured in millimeters (mm).

The maximum width in Millimeters (convert inches by making into decimal and multiplying by 25.4) Example: 2 and 3/8's of an inch becomes 2,875 inches * 25.4 = 60mm As the crow flies, not along the curve of the lens.
