Lens material, protection and available finishes
The general technical attribute for this replacement indicates polycarbonate lenses, a lightweight and impact-resistant material for sun use. The listed colour options also include the CRYSTAL designation, so the material naming may vary by selected colour code. Always choose the correct colour code for the lens appearance and performance you want. All listed options are polarized, helping reduce glare from roads, water and reflective surfaces. Colour 78 also includes a blue-grey gradient finish, giving the RB3478 a more contemporary look while keeping a sun lens configuration.Authenticity and Ray-Ban logo
As original Ray-Ban replacement lenses, they include the Ray-Ban logo on the appropriate lens and the distinctive RB etching on the other lens. Polarized versions may carry the Ray-Ban P marking associated with polarized Ray-Ban lenses.Why replace only the lenses
If your RB3478 frame is still comfortable and in good condition, replacing the lenses is a smart way to restore your sunglasses. It helps keep the original fit, refresh the look and avoid replacing a frame you already like.Frequently asked questions

How to install Ray-Ban RB3478 replacement lenses
Before fitting the lenses, confirm that your sunglasses are Ray-Ban RB3478 and that the size marked inside the temple is 60 mm. This model is typically fitted through a metal rim with a small retaining screw, so work carefully and avoid twisting the frame.
- Place the opened sunglasses on a soft cloth.
- Use a suitable precision screwdriver for the rim screw.
- Loosen the screw only enough to release the old lens.
- Remove the lens gently without bending the bridge or the rim.
- Insert the new lens in the correct orientation and make sure it sits fully in the groove.
- Tighten the screw carefully without over-tightening.
If the lens does not sit evenly, do not force it. A wrong size or a distorted frame may prevent proper fitting. When in doubt, take the sunglasses to an optical professional to avoid damaging the metal frame or the new lenses.
