There is no way in H____ that anyone can wear a pair of spectacles with a 16 diopter difference in powers. The image size with any type forward lens would be far too different, the depth preception would be non-existant and the Ring Scotoma's in the +8.00 lenses would present a new set of problems. You might manage to have sucess with this in contact lenses, but even then you would probably have to reduce the + in the +8.00 to achieve image symetry at the cost of some distance acuity.
This is why in the days of non-pseudophakic cataract surgery, one had to frost the lens on the eye with the poorest acuity until both eyes had been operated on.
Trying to do this in a PAL would be beyond the futality of spiting into a strong wind.
