Bringin’ sexy back! The second part in our look at the nominal lens formula, a way of looking at and thinking about the basics of lens design. The formula allows us to determine the approximate power of a lens (DL) by understanding the relationship between the lens front base curve (D1) and the curve or curves placed on the back of it (D2). This week we solve for D2 when we have DL and D1. Watch it. You know you want to. | Laramy-K OpticianWorks
