Flipper lenses

It is often convenient to offer a patient a small adjustment in the spherical power of a prescription. For example, is it any clearer with -0.25DS, is it any worse with +0,25DS.

This can be achieved by simply selecting the Sph value and changing the power using the mouse wheel. However, the Flipper offers a rather more convenient solution.

To change the spherical power in one eye, simply select the lens power from the rack. This power will then be added to the current prescription. For example, to offer a +/-0.25 lens, simply click on the +0.25 then -0.25 lens in the rack. To remove the additional lens, select None.

To present the same powered lens to both eyes simultaneously (binocular flipper), select the Monoc/Binoc button on either of the flipper racks.
