Before changing lenses
Firstly, fold the temples on both sides when replacing lenses. Then follow the steps below.
The lock parts will not open if the temples are not folded (including when installed), so please handle them with care.
When removing the lens
-
Open the side cover next to the lens outward on both sides. -
Move the nose part of the frame inward on both sides and remove it from the lens. -
Remove the lens from both of the edge of the frame, then from top of the nose part.
When attaching the lens
-
Insert the center of the lens into the upper nose frame. -
Insert the lens edge into both sides of the frame and move the nose part inward a bit to incert the lens accurately. -
Close the side covers inward on both sides until you listen "click" sound.
