Reinsert lenses back into the frame.

To reinsert your lenses, place one hand at the top of the frame where you are inserting the lens.

Place the lens into the groove of the frame, holding it down with your thumb.

Press the lens along the edge of the frame, and the lens will pop back into the frame.

If the lens is difficult to insert, warm up the frame a little bit to make it more malleable. The lens should pop back in without too much pressure.
