Ray-Ban 3379 Replacement Lenses

Original Ray-Ban RB3379 replacement lenses for sunglasses

Restore your sunglasses with original Ray-Ban replacement lenses made for the Ray-Ban RB3379 model. These lenses are designed to preserve the original fit, look and optical performance of your frame, making them a smart choice when the frame is still in good condition but the lenses are scratched, damaged or worn. If you are looking for original Ray-Ban lenses, this RB3379 lens replacement offers genuine Ray-Ban styling with polarized lens options for everyday sun use.

Compatibility with the model

These lenses are intended for the Ray-Ban RB3379 frame in size 64 mm. Before ordering, check the reference printed or engraved inside the temple of your sunglasses. It should show RB3379 together with the lens size, bridge and temple length. A close visual match is not enough: the model code and size must match for a correct fit. They are made for original Ray-Ban frames. Replica frames or look-alike sunglasses may have small differences in groove shape, screw position or lens outline, and those differences can prevent proper installation. They should not be used on other Ray-Ban models with a similar pillow shape.

Lens material, protection and available finishes

The general lens material is listed as polycarbonate, while the colour variants specify their own material: code 57 is a mineral glass lens and code 58 is a plastic/organic lens. For this reason, the material should be checked by colour code when choosing your replacement lenses. Both available options are polarized lenses. Polarization helps reduce reflected glare from roads, water and other shiny surfaces, which can make vision more comfortable while driving or spending time outdoors. Brown polarized lenses offer a warmer view and good contrast, while green polarized lenses provide a more neutral colour perception with a classic Ray-Ban look.

Ray-Ban authenticity and logo

As original Ray-Ban lenses, they include the Ray-Ban logo and the typical brand detailing. Depending on the lens side and version, original Ray-Ban lenses may also feature the discreet RB engraving. Polarized options commonly display the Ray-Ban P marking.

Why replace only the lenses

Replacing only the lenses lets you keep a comfortable frame, extend the life of your sunglasses and regain clear vision without buying a complete new pair. It is especially useful when the frame is structurally sound but the lenses have scratches, marks or reduced visual clarity.
