Tutorial
How to change your sunglass lenses?
- Prepare your glasses: Wash your hands and place the glasses on a clean, soft surface to avoid scratches.
- Loosen the frame screw: Use a precision screwdriver to carefully loosen the screw holding the lens. Keep it in a safe place so it doesn't get lost.
- Remove the old lenses: Once the screw is loosened, gently slide the lens out, avoiding excessive force to prevent damaging the frame.
- Align the new lenses: Make sure the new lenses match the curvature and shape of the frame.
- Insert the new lenses: Carefully insert the lens into the frame and replace the screw, tightening it gently to ensure a secure fit without overtightening.
- Verify and clean: Ensure the lenses are properly fitted and clean the surface with a microfiber cloth.
It's that easy! Enjoy your refreshed glasses with new lenses.
