F2 = F1/ (1-xF1) F2 (what you are solving for) is the converted diopter power corrected for vertex distance. We can use this formula to solve for F2 whether it is from spectacle RX to contact lens RX, or vise versa. F1 is the original lens power in diopters, whether it is the contact lens RX or spectacle RX. Be sure to include the appropriate.

The corresponding number in that row is the power of the contact lens you'll need. Let's say the spherical power of the eyeglass prescription is -8.00 D. If you look up 8.00 on a standard vertex chart, you'll see that the corresponding minus power is -7.25D. This patient needs a contact lens power of -7.25D.

The following formula is used to calculate a contact lens vertex correction. Fc = F / (1-xF) F c = F /(1 − xF) Where Fx is the power corrected vertex distance. F is the original lens power. x is the change in vertex distance in meters. To calculate the contact lens vertex, divide the original lens power by the result of 1 minus the change in.
