How to Change the Temples of Your Ray-Ban Glasses? (Plastic)
- Prepare your glasses: Place your glasses on a clean, stable surface to avoid damage.
- Locate the adjustment mechanism: Identify the connection point between the temple and the frame, usually secured by a screw or a snap mechanism.
- Remove the old temple: If there is a screw, carefully loosen it with a precision screwdriver. If it’s a snap mechanism, gently pull outward to release the temple.
- Insert the new temple: Align the new temple with the hinge or connection point and either tighten the screw or press gently until it clicks into place.
- Check the fit: Open and close the temples to ensure smooth and stable movement.
Done! Your Ray-Ban glasses are as good as new. ️
