How to change the glasses
Take the glass off
1. Wear gloves
2. Hold the glass itself on the side or on the edge and bend the frame upwards.
The frame should come off the glass a little bit.
3. Same on the other side
4. Choose a side and lift the frame further up. Grab the glass as in step 2 or 3. You can also grab underneath the frame and lift it from there, as soon as the gap is big enough.
5. Lift the frame all the way up and it should come off.
Inserting the glass
1. Start by putting one edge of the glass into the edge of the frame
2. If done, your glass should be in a kind of sideway angle like on the photo.
3. For the second side, bend the frame a little with your left hand and put the edge into the edge again.
4. Now press the frame into the glass with both hands until you hear two clicks!
5. Adjust the frame so it is straight.
You will surely get the right twist soon, as we have already changed the glass for you once it shouldn't be too hard - and it gets easier from time to time.
