Ed Measurement On Eyeglasses. The ed is 2x the longest radius and. ed = effective diameter which may be helpful in helping the optician lay out the ideal lens focal position and in determining the size. the ed measurement is twice the distance of the farthest point from the geometric center. you can measure the longest diameter but it is not the effective diameter (ed) that your lab requests. box measurement definitions and additional verbiage to help with following formulas. this course will take the eye care professional (ecp) through the correct steps to measure and adjust a frame prior to. the ed measurement is twice the distance of the farthest point from the geometric center as shown below: A = width of the lens b = height of the lens. The green line above now indicates the ed for this frame. The green line now indicates the ed. Using this example, the green line measures 27mm. As mentioned above, we just need to multiply 27mm by 2 which gives us the correct ed of 54mm. the ed defines the minimum diameter lens that will fit a frame when the geometric center of the lens is exactly.
