Tutorial
How to replace your sunglass lenses?
- Place the frame on a clean, soft surface.
- Gently press the old lens from the back outwards until it pops out. Never force it.
- Align the new lens with the frame groove, starting from the nose-bridge side.
- Press the outer edge gently until it clicks into place.
- Verify the lens sits evenly and clean with a microfiber cloth.
Prescription lenses: We recommend visiting an optician for professional installation.
