I do not think that the first prescription
-6.62 -2.95 × 180
-7.13 -3.22 × 180
is compensated twice but can not say that I am 100% sure.
This is how I see this.
Most of the time you input the Drs. RX also known as uncompensated Rx and frame pano and frame panto and a compendated Rx is calculated. When the lab grind the lenses they expect to read in the lensmeter the compensated Rx.
In this case we go in the other way.
I have a frame with two lenses that I measure to get the compensated Rx and have a frame from where I get pano and panto. This is the information of the glasses the patient is wearing.
With this information (like reverse ingeneering) I calculated a uncompensated Rx. And use it as input to calculate a new pare of glasses.
If this is true, the prescription
OD -6.50 -2.75 x 180
OI -7.00 -3.00 x 180
Is the compensated one.
But might be wrong and this is why I posted it to hear other opinions.
And why I will do two jobs on the lab. One with each prescription.
