Additionally, in some cases, the manufacturer may apply an impact absorbing primer coating in order to allow for thinner centers. Although vision through the center of a lens will be relatively sharp no matter what the form, vision through the periphery of a lens will vary greatly as a function of lens form. And, since the sum of the front surface power and back surface power is equal to the total focal power of the lens, we finally arrive at one simple equation for the maximum thickness of both plus and minus lenses:.
