is Eyeglass Frame line item deduction supposed to include cost for both the Rx lenses AND the frames?

Hi, Is the "Eyeglass Frames" deduction item supposed to include the cost for BOTH the prescription eyeglass lenses AND the frames together?    Or are you supposed to only list the cost of the frames there separately and list the cost of the prescription eyeglass lenses on the separate line item called "Prescriptions"?
