In an inscription such as RB3682 ··· 51□·· ···, each part has a purpose:
The RB3682 has a metal frame. This pair of original lenses keeps the geometry, beveling and fit designed for the model; you just need to confirm the exact reference and lens size.
We work with original replacement parts and help you confirm the model and lens size to reduce mistakes before we prepare your order.

The metal frame uses a rim closed with a screw. Work on a protected surface and avoid forcing the lens or bending the frame front.
If the lenses in your Ray-Ban RB3682 are scratched, chipped or simply tired, you do not need to replace the whole pair of sunglasses. These original Ray-Ban RB3682 replacement lenses restore clarity and the original look of your frame for much less than buying new sunglasses, with free shipping on qualifying orders.
At ReplacementLenses.net, every order is handled by qualified opticians in our own workshop in Granada. We work with MEI Easy Fit Trend technology, verify lenses with a lensmeter and operate as an official EssilorLuxottica distributor.
These replacement lenses are made for the Ray-Ban RB3682 in size 51. They match the original irregular lens shape and Base 6 curvature of this specific frame.
Do not use them for other Ray-Ban models just because they look similar. With original lenses, even a small difference in shape, size or curve can prevent a safe and accurate fit.
Check the inside of the temple arm of your sunglasses. You should find the model reference RB3682 and the lens size 51 printed there. The size number refers to the lens width and must match the replacement lens you order.
If your frame reads RB3682 51, this is the correct replacement. If you see a different model or size, verify it before ordering.
Choose by the colour code whenever possible. Screen colour may vary, but the Ray-Ban code identifies the exact available lens option.
The product attributes indicate glass lenses, while the individual colour options are listed as plastic in the colour catalogue. The lenses provide UV400 protection, blocking 100% of UVA and UVB rays.
Available lens options include gradient finishes, dark blue and photochromic gradient variants. No polarized option is listed in the product attributes, so only select polarization if a variant is explicitly marked as polarized.
The metal frame of a Ray-Ban RB3682 often remains in good condition long after the lenses have become scratched. Replacing only the lenses is a smarter and more sustainable choice: you save money, reduce waste and keep the frame that already fits your face well.
Compared with buying a complete new pair, original replacement lenses can make your sunglasses look and feel renewed at a fraction of the cost.
As original Ray-Ban lenses, these replacements include the Ray-Ban logo. We source through official EssilorLuxottica channels, so you receive authentic lenses rather than generic copies.
Since 2018 we have repaired more than 600,000 glasses, processed over 400,000 orders and shipped to more than 50 countries. Our opticians check every lens with professional optical equipment before dispatch.
