Before changing lenses
When replacing lenses, first fold the temples on both sides and follow the steps below.
The lock parts will not open if the temples are not folded (including when installed), so please handle with care.
When removing the lens
-
Hook your finger on the convex part of the lock part. -
Rotate the lock part outward to release the lock. -
Hold the outer lens edge and slide it in the direction of the arrow to remove the lens.
When attaching the lens
-
Insert the convex part on the nose side of the lens into the groove of the frame, and push in the convex part on the outside of the lens until there is no gap. -
Rerote the lock part inward while hold the frame and lens. -
Press the lock part with your finger until you hear a "click" sound to secure the lens.
