These lenses are made for the Ray-Ban 3684CH model in size 58. With metal frames, the lens shape, bevel and curve must match the rim precisely, so checking the model code is essential before ordering.
The lens shape is irregular and the lens curve is Base 6. This helps preserve the original fit and appearance of the RB3684CH. If you are unsure whether your frame is RB3684 or RB3684CH, check the code printed inside the temple.
Look inside the temple arms of your sunglasses. You should find the model reference 3684CH and the size 58. That size is the lens calibre and determines whether the replacement lenses will fit correctly.
If the markings are faded, send us a clear photo of the frame and temple codes. Our optical team works with Ray-Ban replacement lenses every day and can help you confirm the correct model before purchase.
These original Ray-Ban lenses are made of glass, as specified for this replacement. All available lens options for this product are polarized, helping reduce glare from roads, water, bright surfaces and reflective environments.
They also provide UV400 protection, blocking 100% of UVA and UVB rays. This is one of the key reasons to choose genuine lenses rather than generic alternatives: you keep the optical safety and visual quality expected from an original Ray-Ban product.
Your RB3684CH metal frame may still be in excellent condition even if the lenses are scratched. Replacing just the lenses is a smart choice: you spend less, reduce waste and keep the frame that already fits you well.
