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 your Ray-Ban RB3681 frame still fits perfectly but the lenses are scratched, worn or damaged, replacing only the lenses is the smart way to refresh your sunglasses without buying a new pair. These original Ray-Ban RB3681 lenses keep the look, protection and fit of the model, with free shipping on qualifying orders and savings compared with new sunglasses.
At ReplacementLenses.net we work every day with original Ray-Ban lenses. We are an official EssilorLuxottica distributor, with our own optical workshop in Granada and qualified opticians checking every lens.
These Ray-Ban replacement lenses are made for the Ray-Ban RB3681 in size 50. They are not universal lenses for any round or Phantos-style Ray-Ban frame; the shape, diameter, Base 6 curve and metal-rim fit are specific to this model.
We recommend fitting them only to an original Ray-Ban frame. Replica frames can have small differences in the rim that prevent the lens from seating correctly.
Look inside the temple arm of your sunglasses. You should find the model reference RB3681 and the lens size 50 printed or engraved on the frame.
Ray-Ban frame codes usually show the model first, then frame colour information and measurements. For this purchase, the key checks are RB3681 and 50. On a metal frame, choosing the wrong size can leave the lens loose or under pressure.
These Ray-Ban RB3681 lenses are made from polycarbonate, a lightweight material suited to everyday sunglasses. The Base 6 curve follows the optical geometry of the model and helps preserve the original wearing experience.
They provide UV400 protection, blocking 100% of UVA and UVB rays. If you are looking for polarised lenses, choose only a lens option explicitly marked as polarised; the options listed here are not described as polarised.
The metal RB3681 frame is durable and often remains in excellent condition long after the lenses have been scratched. Replacing only the lenses lets you keep the premium frame you already like, reduce waste and bring your sunglasses back to life at a fraction of the cost.
Because these are original Ray-Ban lenses, they include the Ray-Ban logo. This is one of the key differences between genuine lenses and generic compatible alternatives.
