How it works?
To clean the lens is as easy as 3 steps to take. It can either be done on your hand or in wearing the sunglasses
Step 1 Push the lens up from the bottom edge while holding the frame still as indicated by the demo.
Step 2 Lower the lens back down by pushing on the grooves from the top edge of lens. Repeat up and down few times for better result if required.
Step 3 After cleaning the lens, press the lens down to align edge with frame so can engage together stably.
