Of course, simply divide the NV-ADD or ADD in half. For example,

ADD: +2.50/2 = +1.25
Now +1.25 is your new NV-ADD.

Leave one half as reading additional and add the other half of NV-ADD in SPH value. For example,

SPH: -1.00 and NV -ADD =+2.50
Now, Near NV-ADD = -1.00 +1.25 = +0.25

Now, you have got your computer glasses Rx as SPH = +0.25 and ADD = +1.25.
