prescription autofold eyeglasses: auto-fold has a precision crafted spring mechanism, small size and almost unnoticeable, hidden in the end piece. this unique device allows the temple to be twisted smoothly in the downward direction. the frame will automatically collapse into the flat case when the id is closed. this mechanism eliminates the hassle of folding and unfolding in a traditional mechanical reader while retraining the small size for convenience.
