How to Identify Your Eyeglass Frame Model Number
Finding the correct model number for your eyeglasses is essential when ordering replacement parts. This guide will help you locate model numbers, color codes, and size information for all major eyewear brands.

- Size measurements - Lens width, bridge width, and temple length
- Brand name - Manufacturer identification

What If I Can't Find My Model Number?
If the markings on your frames have worn off or are illegible:
- Check the original case - Model numbers are often printed on the case or cleaning cloth
- Look at the receipt - Purchase receipts usually include the full model number
- Measure your frames - Use a ruler to measure lens width, bridge, and temple length
- Take a photo - Send us clear photos of your frames and we can help identify the model
- Contact us - Our team can help identify your frames based on photos and measurements
Why Model Numbers Matter
Knowing your exact model number ensures you order the correct replacement parts:
- Nose pads - Different models use different sizes and attachment styles
- Temples - Must match your frame's hinge type and color
- Lenses - Must fit your specific frame shape and size
- Screws - Vary by frame construction and material
