Original Ray-Ban RB3686 Replacement Lenses

Original Ray-Ban RB3686 replacement lenses

If your Ray-Ban RB3686 frame is still in good condition but the lenses are scratched, replacing only the lenses is the smart way to get your sunglasses back without buying a new pair. These original Ray-Ban lenses for RB3686 keep the authentic fit, UV400 protection and optical feel, with free shipping and savings of up to 60% compared with new sunglasses.

Model compatibility

These Ray-Ban replacement lenses are made for the Ray-Ban RB3686 model in size 57. Always check the reference printed inside the temple, because similar Ray-Ban models may look close but use a different lens shape or size.

As original Ray-Ban lenses, they are designed for the exact geometry of the genuine RB3686 frame. If your frame is a replica, fit cannot be guaranteed because the inner groove and lens curve may differ.

How to identify your model and size

Look inside the temple for a code such as RB3686 57□19. RB3686 is the model number, while 57 is the lens size, meaning the width of each lens in millimetres. It is not the total width of the sunglasses.

Before ordering, make sure your frame shows RB3686 and size 57. If you are unsure, send us clear photos of the inside temple and the front of the frame.

Material, protection and lens options

These RB3686 lenses are made of glass, with a Base 6 curve and UV400 protection, blocking 100% of UVA and UVB rays. Depending on the selected colour, you can choose classic, gradient, polarised and polar mirror lens options.

Polarised lens options reduce disturbing glare when driving or near reflective surfaces. Original Ray-Ban polarised lenses carry the Ray-Ban P logo.

Why replace only the lenses

The metal frame of the RB3686 is built to last. Replacing the lenses is more economical, more sustainable and lets you keep the frame that already fits your face comfortably.

Frequently asked questions

Do these lenses fit every Ray-Ban RB3686?

They fit Ray-Ban RB3686 frames in size 57. Please check the temple code before ordering to avoid confusion with similar models.

How do I know if my sunglasses are really RB3686?

The model number is printed inside the temple. If it shows another code, do not assume compatibility based only on appearance.

Are these original Ray-Ban lenses?

Yes. They are original Ray-Ban lenses supplied through the official EssilorLuxottica channel and include the Ray-Ban logo.

Are polarised options available?

Yes. The available polarised options are K8 – polar dark grey, P1 – polar dark green and 4L – polar mirror blue, all in glass.

Can I replace only one lens?

For the RB3686, replacing both lenses keeps colour, filtration and visual balance symmetrical. A new lens next to a used one may show a visible tone difference.

Can I install them at home?

The RB3686 is a metal frame, so the rim screw is normally loosened before fitting the lens. If you are not used to this type of frame, we recommend professional installation.
