Original Ray-Ban RB3689 replacement lenses
Bring your Ray-Ban RB3689 sunglasses back to clear, sharp vision without buying a new frame. These original Ray-Ban replacement lenses help you save money, keep the metal frame that already fits you and enjoy free shipping on qualifying orders.
Model compatibility
These lenses are made for the Ray-Ban RB3689 model. For a correct fit, your frame reference must be RB3689 and the lens size must match one of the available sizes: 55, 58 or 62.
Do not fit them into other Ray-Ban models or replica frames. With metal eyewear, even a small size difference can prevent the rim from closing properly or create stress on the glass lens.
How to identify your model and size
Check the inside of the temple arm. You should find the model code RB3689 followed by the lens size, such as 55, 58 or 62, together with the bridge and temple measurements.
The lens size is the eye size in millimetres, measured across the widest horizontal point of the lens. If you are unsure, do not force the frame; confirm the engraving before ordering.

Material, protection and lens options
According to the technical attributes for this RB3689 spare part, the lenses are made of glass. This material is valued for optical clarity and scratch resistance, while UV400 protection blocks 100% of UVA and UVB rays.
Some lens options are specifically marked as polarized, such as 48 – Black polarized and O9 – Polar green AR blue. If you want polarization, choose only a colour option where polarized is clearly stated.
Why replace only the lenses
If your Ray-Ban RB3689 metal frame is still in good condition, replacing the lenses is the smart choice. You restore comfort, appearance and sun protection at a fraction of the cost of a complete new pair.
It is also a more sustainable repair: you keep using a high-quality frame that is already adjusted to your face instead of discarding it because the lenses are scratched or damaged.

Frequently asked questions
Are these lenses compatible with other Ray-Ban models?
They are intended for the Ray-Ban RB3689 only. Similar-looking metal frames may have different lens shape, size or curve, so we recommend matching the exact model code.
How do I know whether I need size 55, 58 or 62?
Look at the engraving inside the temple arm of your RB3689. The eye size printed there must match the size you select when ordering.
Can I fit size 58 lenses into a size 55 frame?
No. Forcing a wrong size into a metal RB3689 frame can bend the rim, damage the screw area or crack the glass lens.
Are these original Ray-Ban lenses?
Yes. This is an original Ray-Ban spare part, supplied through our official EssilorLuxottica distributor channel.
Are the lenses glass or plastic?
The lens material for this product is glass. That gives the RB3689 replacement lenses excellent optical clarity and strong scratch resistance.
Can I choose polarized lenses?
Yes, but only by selecting an option that is explicitly marked as polarized, such as 48 – Black polarized or O9 – Polar green AR blue. Other colours should not be treated as polarized.
Can I install them at home?
The RB3689 is a metal frame, so the lens is replaced by carefully opening and closing the rim screw. If you feel resistance or lack the right experience, have an optician fit them.
Example for guidance only. The position and order of the codes may vary depending on the frame.
