Simulation

Using the lens meter simulation, determine the
Add Power of the right lens of this pair of bifocals.

The right lens of this pair of flat-top bifocals is positioned at the optical center, with the back
side of the lens facing you. You can also see the same lens as it would appear when positioned at
the center of the bifocal segment. To see one view
or the other, use the control arrow. You can determine the optical power in either view.

When you have determined the Add Power of the lens, determine whether the lens meets optical standards for Add Power.
