Identifying your sunglasses is the most important step to ensure your new lenses fit perfectly. We'll show you where to look on your frame to make sure you get the right lenses for your sunglasses.

How to Identify Sunglasses

Brand Name

Start by looking for a logo or name printed on the frames to identify which brand of sunglasses you have. This brand name may be on the outer or inner arm of the frame.

Frame Name

Find the frame name by looking for a logo or name printed on the inside temple of the frames.

Pay special attention to qualifiers like an "S" or an "XL" that indicate frame or lens size. These special frame sizes usually have their own, unique lenses, which aren’t interchangeable with other size variations of the same frame.

Some frames had multiple editions made over the years. If you search your frame name and see a year listed after it, like Oakley Straight Jacket (2007), click the "Check Compatibility" button on the product page. You can use the images in the fit guide to identify which generation your frames are.

Frame Number

If you don't see a frame name on your sunglasses, there may be a SKU number to identify your frames. A SKU usually looks something like this:

  • Oakley frame SKU example: OO9102
  • Ray-Ban frame SKU example: RB2132
  • Maui Jim frame SKU example: MJ103

You can search these SKU numbers on our site to find the right lenses for your frame.

Lens Size

Some Ray-Ban frames have multiple sizes. The size is usually a number found after the SKU before the square ▢ symbol indicating the millimeter width of the lens.

RB 2132 New Wayfarer 901 52 18 3N indicates a Lens Size of 52mm

Example: Ray-Ban New Wayfarer RB2132 52mm sunglasses

Lens Width

One of the best things about Revant is breathing new life into older frames. Unfortunately that sometimes means identifying numbers such as lens width have worn off. While the printed number is the most accurate way to know the mm size, you can also get the lens size by measuring the widest horizontal measurement in millimeters of the lens. To ensure an accurate measurement, remove the lenses and measure across, straight across, not angled. If you measure the lens when they are inside the frame, you will get an incorrect measurement.

Check Compatibility

We provide a Check Compatibility button on our lens product pages for commonly confused frame styles with additional resources to help you double check you're getting the right lenses.
