Change of prescription: new glasses are no good, why?

[pleighg]

I wear progressive glasses and have no problem with them at all. I wanted to buy some prescription sunglasses with the current prescription but was told I need a new exam. The O.D. gave me this RX:

old: (my current)
Right: -0.25 sph, +0.50 cyl, 095 axis
Left:   -1.50 sph, = 2.75 cyl, 087 axis

New
Right: +0.50 sph, -0.50 cyl, 013 axis
Left:   +1.50 sph, -3.00 cyl, 175 axis

I purchase a very expensive pair of sunglasses (maui jim) to get superior optics, but when I got the sunglasses and tried them they did not feel comfortable. Too much adjusting my eyes, feeling like my feet were not on the ground, etc.

The Maui Jim glasses are small but have a bit of a wrap (8 base). I have been told various things from various opticians, either that it is the fault of the curved lens or that my RX changed and should not have.

Any idea? The glasses were checked and were done correctly. Is it the fault of the RX or the fault of the curved lens? Thank you!

The old prescription is written in plus cylinder (for the astigmatism); I am assuming that the sign before the 2.75 is +.  The new prescription is written in minus cylinder.  The prescriptions are almost the same, except for the astigmatism axis of the right eye.  If you add the first 2 numbers together, change the sign of the middle number (astigmatism), and change the axis by 90 degrees, the 2 prescriptions are almost the same.  It may be the curvature that is bothering you.  If you cannot adapt with time, you may want to have them change the frame.
