The invention relates to an electro-optic lens having a integrate element, specifically, a spectacle lens having electric excitations on an outer perimeter. The invention comprises: an electric excitations spaced from each other on the out perimeter, wherein each excitation element has two surfaces, and includes electric excitation material to adjust lens focal length between the surfaces. The electric excitation element does not adjust lens focal length in case of no electricity, and the lens has at least two different optical enlargement ratio and mediating transition of optical enlargement ratio therebetween in case that electricity is applied. |
