Changing the lenses
The lenses of the sports sunglasses can be replaced within seconds thanks to the specially developed
magnetic holding system.
Loosen the lens:
To change the lenses, hold the SUNUP frame with one hand while pulling the lens downwards with the
other hand, releasing it from the magnetic locking system.
Inserting the lens:
Hold the interchangeable lens in one hand while holding the frame with the other hand. Now insert the
upper edge of the interchangeable lens into the lens guide under the frame. The lens will automatically
lock into place on the magnetic locking system once it is in the correct position.
