How to Find The Model and Size To Get Correct Replacement Lenses for Your Sunglasses

When searching on our site putting in less is better than more. We store replacement lens information at the model level which is usually the four numbers or name of your frame. We do not store all the subsequent number as those refer to all the frame and lens combinations the manufacturers use.
Therefore, if you have a Ray Ban frame look for the RB#### number of the arm. Just type the #### numbers in the search engine and it will probably only display a few models along with their photos. 
Ensuring the lens width measurement is always very important. So find the two numbers usually preceding a small square or measure your sunglasses as instructed below to ensure you get the right lenses for your frames.

Many brands such as Persols, Pradas, and Ray Ban Sunglassses 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.

So how to you determine which is the the size and model of your current frames? You can measure them at their widest point as the crow flies. However, with two to three millimeters difference it can be hard.

Most sunglasses have a writing on the arms or under the nose bridge that should provide the required information. Additionally, the information may be on your original packaging. However, it's always best to check your frames we have seen many major department stores pack the sunglasses in the wrong boxes.
