How to Identify Your Sunglasses Model, Size, & Brand Info (Oakley, Ray-Ban, & More)Updated 2 hours ago

Finding the correct replacement lenses starts with identifying the details printed on the inside temple arm (stem) of your sunglasses. Frame sizes consist of three measurements in millimeters (mm): Eye Size (Lens Width), Bridge Size, and Temple Length.

Knowing your Frame Name, Model Number, and Eye Size ensures a perfect lens fit every time.

Understanding the Numbers on Your Frame Temple

1. Frame Model / Name (Essential ⭐)

• Displays the specific design name or model number assigned by the manufacturer.

• Can appear as a name (e.g., Justin, Holbrook), a series of numbers, or a combination of letters and numbers.

2. Eye Size / Lens Width (Essential ⭐)

• The horizontal width of a single lens in millimeters (mm), typically ranging from 40mm to 70mm.

• Finding It: Located immediately before a small square icon ▢ (or before the brand logo separator).

• Fit Tip: Eye size is the most critical number for ordering replacement lenses! If your frames list an eye size that differs by just a few tenths of a millimeter from our listing, it will still fit smoothly.

3. Bridge Size (Ignore for Lenses)

• The distance between the two lenses across the nose, ranging from 14mm to 24mm.

• Located immediately after the small square icon ▢. (Not needed for ordering replacement lenses).

4. Temple Length (Ignore for Lenses)

• The 3-digit length of the arm from hinge to tip, usually ranging from 130mm to 160mm. (Not needed for ordering replacement lenses).

5. Color Code & Lens Category (Optional)

• Color Code: A sequence of numbers or letters following the model number. (Not needed for ordering lenses).

• Lens Category (Tint & Polarization): Displays a number (0–4) and a letter (P for Polarized, N for Non-Polarized). Example: 3P = Category 3 Polarized lens.

  • Category 0–1: Clear to light tint (night or weak sunlight).

  • Category 2: Medium tint (general daily wear).

  • Category 3: Dark tint (bright sunlight, water, sports). Most Fuse lenses fall here.
    

Safety Glasses Marking Notice (Z87 / ANSI)

If your frames display Z87 on the temple arm (common on Wiley X and safety frames), they meet ANSI safety standards.

Important Note on Safety Ratings: Replacing the original factory lenses in safety frames voids the original frame safety certification. While all Fuse Lenses surpass ANSI Z87.1 impact resistance standards, we cannot apply official safety stamps to replacement lenses because ANSI requires testing while the lens is factory-assembled in the specific frame.

Brand-Specific Identification Guides

🕶️ How to Identify Oakley Sunglasses

Oakley uses names and unique model number formats stamped on the inside temple arm. Always check the model code, as classic Oakley styles evolve over time!

• Older Oakley Models (Format: NN-NNN):

  • Example: 03-365 | 59 ▢ 12

  • How to read: 03-365 is the model number. 59 is the eye size (separated from the 12 bridge size by an Oakley "O" logo instead of a square).
    

• Newer Oakley Models (Format: OO or OX + 4 Digits):

  • Example: OO9295-01 | 59 ▢ 12

  • How to read: The numbers start with OO (letters O-O, not zeros). OO9295 is the model number (e.g., Flak 2.0). The -01 after the dash is the frame color code.

  • Prescription (Rx) frames start with OX (e.g., OX1066-03).

• 

🕶️ How to Identify Ray-Ban Sunglasses

Ray-Ban prints model details on the inside left temple arm. For metal frames (like Aviators), look closely or use a magnifier near the bridge or arm hinge!

• Ray-Ban Model Format (RB + 4 Digits):

  • Example: RB4165 Justin 622/T3 54 ▢ 16 145 3P

  • How to read:

    • Model Number & Name: RB4165 (Justin)

    • Color Code: 622/T3 (ignore for lenses)

    • Eye Size (Lens Width): 54 (located on the left of the ▢ square — Essential for ordering!)

    • Bridge Size / Temple Length: 16 / 145 (ignore for lenses)

    • Lens Filter: 3P (Category 3 Polarized)

Frequently Asked Questions

• What is the most important number I need to find my replacement lenses?

  • You need the Brand Name, Model Name/Number, and the Eye Size (the 2-digit number before the square ▢ icon).

• My eye size differs by 0.5mm from what is listed on Fuse Lenses. Will it fit?

  • Yes! Manufacturers occasionally round lens dimensions on frame stems. A variance of a fraction of a millimeter will still fit cleanly.

• Does changing my Wiley X or safety lenses void the ANSI rating?

  • Yes. Installing replacement lenses voids the official frame rating because ANSI requires testing the full assembly together at the factory.
